Explain how the Law of Conservation of Mass is demonstrated In photosynthesis and cellular Respiration chemical equations. (Less than a paragraph please)
Explanation:
According to the law of conservation of mass, In a chemical reaction, mass is neither created nor destroyed. In other words, the total mass for the reactants needs to equal the total mass of the products. In photosynthesis the reactants are 6 carbon dioxide, 6 water and sunlight. The mass of these reactants adds to equal the mass of the products, which are 1 glucose and 6 oxygen. Cellular respiration on the other hand uses glucose and oxygen gas to produce water, carbon dioxide, and a usable form of energy known as ATP.Cellular respiration is the opposite of photosynthesis, such that the products of photosynthesis are the reactants of cellular respiration. Cellular respiration also obeys the law of conservation of mass.The Law of Conservation of Mass is demonstrated in photosynthesis and cellular respiration as no matter is created or destroyed during these processes, maintaining a consistent atomic mass throughout.
Explanation:In photosynthesis and cellular respiration, the Law of Conservation of Mass is upheld as no matter is created or destroyed, maintaining consistent atomic mass throughout these chemical reactions. For photosynthesis, for example, six carbon dioxide molecules combine with six water molecules to produce one glucose molecule and six oxygen molecules. Similarly, in cellular respiration, glucose is broken down into carbon dioxide and water, returning these molecules to the environment. Thus, the number of atoms of each element in the reactants equals the number of atoms in the products, supporting the Law of Conservation of Mass.

How many milliliters of a solution of 8.8M CaBr2 are needed to prepare 175 mL of a 2.2M solution?
The product of molarity and volume of any substance at a fixed temperature is constant. Therefore comparing two portions of different molarity, we can say that, M₁V₁=M₂V₂
M represents the molarity, V represents volume of the solution.
M₁ in the question is 8.8M
M₂ is 2.2M
V₁=?
V₂= 175
therefore,
8.8ₓV₁= 2.2ₓ175ml
V₁=(2.2ₓ175ml)/8.8
=43.75 ml
You need 43.75 mL of an 8.8M CaBr2 solution to prepare 175 mL of a 2.2M solution. This is achieved using the molarity formula, M1V1 = M2V2, which helps us to relate the initial and final concentrations and volumes of the solution.
Explanation:To solve this problem, we need to use the concept of molarity (M), which is a measure of the concentration of a solute in a solution. The formula for molarity is M1V1 = M2V2, where M1 is the initial molarity, V1 is the initial volume, M2 is the final molarity, and V2 is the final volume.
In this case, we want to find V1, so we rearrange the formula to: V1 = (M2V2) / M1
Substituting the given values, we get: V1 = (2.2M * 175 mL) / 8.8M = 43.75 mL.
Therefore, you would need 43.75 milliliters of an 8.8M CaBr2 solution to prepare 175 mL of a 2.2M solution.

Empirical formula of n3h9
Empirical formula is nh3
The question seems to involve a composition error, resembling a compound formation reaction. The correct empirical formula for N3H9 after simplification would be NH3, which is the formula for ammonia. The empirical formula represents the simplest ratio of elements in a compound.
Explanation:The question refers to finding the empirical formula of a compound with an initial composition of N3H9. The empirical formula represents the simplest whole-number ratio of atoms in a compound. However, the given composition does not match any common or simple empirical formula, and seems like a simplification error occurred.
We can compare the process to another compound, naphthalene, where a 1.25:1 ratio of moles of carbon to hydrogen leads to an empirical formula of C5H4 once the subscripts are multiplied by 4 to achieve whole numbers. For the compound ammonia (NH3), the balanced equation N2 (g) + 3H2 (g) → 2NH3 shows the correct stoichiometry of nitrogen to hydrogen.
If the composition N3H9 were correct, dividing the subscripts by the greatest common divisor, which is 3, would yield NH3, the formula for ammonia. Thus, the empirical formula for this case would be NH3, and the equation representing the combination process would be: N2 + 3H2 → 2NH3. The empirical formula mass for NH3 would be the sum of the atomic masses of nitrogen and hydrogen.

Photographing the location where the bomb exploded Collecting residue samples from the scene Assessing whether the explosion was a result of a criminal All of the above are equally as challenging.
Answer:
Collecting residue samples.
Explanation:
All the other given options are equally important on the exploration of a bomb aftermath.
The most important task is the collection of residue samples since it needs highly skilled personel to collect accurate samples for later on analysis.
Identification of meaningful collection areas is a technical skill that requires the most experienced team memebers.
Answer: Collecting residue samples from the scene.
Explanation:
Collection of the residues after the explosion will be the most important task that is required to be done immediately this is because of the fact that the explosive residues at the site of the crater may consists of residues which may contain both volatile and non-volatile substances which are likely to be blown away soon after explosion. Thus if not collected in proper time the type of explosive used for explosion will remain undetected.

Scientists study an ecosystem devastated by drought and observe the interactions of organisms in relation to food, light, water and mates. Which hypothesis statement relates to the investigation?
a If the drought continues to increase, then competition will decrease.
b If available resources decrease, then competition will increase.
c If available resources remain constant, then competition will decrease.
d If available resources increase, then competition will increase.
The correct answer is - b. If available resources decrease, then competition will increase.
All living organisms in an ecosystem are specialized in accordance to the living conditions and the food sources available. If a given ecosystem experiences prolonged drought, than the resources will decrease. With a decrease in resources, the living organisms will find themselves in a situation of scarcity. That will lead to a much increased competition, with both organisms of different species, and members of the same species. That will most likely lead to a situation where only the fittest will survive, while the weaker members of the species will probably die in that period of prolonged drought as they will not be able to get the resources they need to survive.
Answer:
B because animals would fight over food and water more to survive
Explanation:
• Define and describe in detail (and in your own words) ultrasound and infrasound
• Describe how ultrasound and infrasound are used in specific industrial applications and provide detailed examples.
Answer:
Human ears can hear sound waves that vibrate in the range from about 20 times a second (a deep rumbling noise) to about 20,000 times a second (a high-pitched whistling). (Children can generally hear higher-pitched sounds than their parents, because our ability to hear high frequencies gets worse as we get older.) Speaking more scientifically, we could say that the sounds we can perceive have a frequency ranging from 20–20,000 hertz (Hz). A hertz is a measurement of how often something vibrates and 1 Hz is equal to one vibration each second. The human voice makes sounds ranging from a few hundred hertz to a few thousand hertz.
Suppose you could somehow hit a drum-skin so often that it vibrated more than 20,000 times per second. You might be able to see the skin vibrating (just), but you certainly couldn't hear it. No matter how hard you hit the drum, you wouldn't hear a sound. The drum would still be transmitting sound waves, but your ears wouldn't be able to recognize them. Bats, dogs, dolphins, and moths might well hear them, however. Sounds this like, with frequencies beyond the range of human hearing, are examples of ultrasound.
Infrasonics, vibrational or stress waves in elastic media, having a frequency below those of sound waves that can be detected by the human ear—i.e., below 20 hertz. The range of frequencies extends down to geologic vibrations that complete one cycle in 100 seconds or longer.
How many kilojoules of heat are required to melt a 10-g popsicle is 0°C ? Assume the particle has the same molar mass and heat of fusion as water.
3.4 kJ
Explanation;Taking the mass of water as 10.0 g
Moles of water = Mass /molar mass
Moles of water in 10.0 g;
= 10g H2O x 1mol/18g
=0.56mol
But, 1 mole of water = 6.01 kJ
Hence;
6.01kJ/1mol H2O= x kJ/.56mol,
x = 3.4kJ
Final answer:
The heat required to melt a 10-gram popsicle at 0°C is approximately 3.34 kJ, calculated using the molar heat of fusion for water and the molar mass of water.
Explanation:
To calculate the number of kilojoules of heat required to melt a 10-gram popsicle at 0°C, we will use the heat of fusion of water. The heat of fusion is the amount of energy needed to change 1 mole of a substance from the solid phase to the liquid phase without changing its temperature.
First, we must find the number of moles in 10 grams of water. The molar mass of water (H₂O) is approximately 18.015 g/mol, therefore:
Moles of water = mass (g) / molar mass (g/mol) = 10 g / 18.015 g/mol = 0.555 moles (approximately)
Next, we use the molar heat of fusion for water, which is 6.01 kJ/mol. The energy (Q) required to melt the ice in kilojoules is:
Q = moles × heat of fusion = 0.555 moles × 6.01 kJ/mol = 3.33555 kJ
Therefore, the heat required to melt a 10-gram popsicle at 0°C is approximately 3.34 kJ.
What is the percent concentration of a sodium fluoride solution made be dissolving 65.4 grams of sodium fluoride in 125.1 grams of water?
Answer:
34.33 %.
Explanation:
To calculate the mass percent or weight percent of a solution, you must divide the mass of the solute by the mass of the solution (both the solute and the solvent together) and then multiply by 100 to change it into percent.W% = [(W of solute NaF)/(W of solution)] x 100.
W of solute NaF = 65.4 g.
W of solution = W of solute NaF + W of water = 65.4 g + 125.1 g = 190.5 g.
∴ W% = [(W of solute NaF)/(W of solution)] x 100 = [(65.4 g)/(190.5 g)] x 100 = 34.33 %.
The percent concentration of the sodium fluoride solution is approximately [tex]\( 34.32 \% \)[/tex].
To find the percent concentration of the sodium fluoride solution, we first need to calculate the total mass of the solution, which is the sum of the mass of sodium fluoride [tex](\( \text{NaF} \))[/tex] and the mass of water [tex](\( \text{H}_2\text{O} \))[/tex].
Total mass of the solution [tex]\( = \text{mass of NaF} + \text{mass of water} \)[/tex]
Given:
Mass of sodium fluoride [tex](\( \text{NaF} \)) \( = 65.4 \) grams[/tex]
Mass of water [tex]\( = 125.1 \) grams[/tex]
[tex]Total mass of the solution \( = 65.4 \, \text{g} + 125.1 \, \text{g} = 190.5 \, \text{g} \)[/tex]
Next, to find the percent concentration of sodium fluoride in the solution, we'll use the following formula:
[tex]\[ \text{Percent concentration} = \frac{\text{Mass of solute}}{\text{Mass of solution}} \times 100 \][/tex]
where:
Mass of solute is the mass of sodium fluoride
Mass of solution is the total mass of the solution
Substituting the given values:
[tex]\[ \text{Percent concentration} = \frac{65.4 \, \text{g}}{190.5 \, \text{g}} \times 100 \][/tex]
[tex]\[ \text{Percent concentration} = \frac{65.4}{190.5} \times 100 \][/tex]
[tex]\[ \text{Percent concentration} = 0.3432 \times 100 \][/tex]
[tex]\[ \text{Percent concentration} \approx 34.32 \% \][/tex]

You are creating a line graph with data from an experiment tracking the growth of a tree over the last year. It is most important that you label the independent variable on the
A.) x-axis.
B.) y-axis.
C.) title of the graph.
D.) line you are graphing.
Answer:
A) The independent variable should be labeled on the X-axis.
Explanation:
• Dependent variables: properties that the researcher or observer can not directly control. These properties usually change as an effect of the change in other property.
• Independent variables: properties whose value can be picked or determined by the researcher to see if they are the cause of a change in the dependent variable.
If you are tracking the growth of a tree over the last year, you would like to know the influence of time on the growth of the tree. You probably have selected some values of time to measure the growth of the tree, it could be every fifteen days, every month or every quarter. As you can influence or pick the value of the time, it is your independent variable, and you can analyze the influence of the chance of time on the tree growth, which is your dependent variable.
Finally, we can say that the time should be labeled on the x-axis, since it is the independent variable.
In a line graph, the independent variable is labeled on the x-axis. This is the variable you control or change in the experiment. Proper labeling of a graph helps clarify the data representation.
Explanation:When you are creating a line graph to track the growth of a tree over the last year, the most important thing is to label the independent variable on the x-axis.
The independent variable is the one that you have control over in your experiment or the one that you choose to change to see if it has an effect on another variable. In this case, the independent variable is time, which you would represent on the x-axis of the graph. The dependent variable, or the one you measure to see if it changes when the independent variable changes, would be the growth of the tree, and this would be represented on the y-axis.
Properly labeling your graph, including both axes and the title, helps you and others understand what the data is showing more clearly.

____ dating uses the properties of atoms in rocks and other objects to find their ages. a. Comparative c. Approximate b. Absolute d. Relative Please select the best answer from the choices provided A B C D
Answer:
b. Absolute
Explanation:
Absolute dating is a method used by scientists to determine the age of objects by evaluating the properties of its atoms, it is also called chronological and calendar dating, since absolute refers to a certainity that the scientists can not warantee when it comes to how long has an object has bein on a certain place.
Absolute dating uses the decay properties of isotopes in rocks to find their exact ages. It depends on radiometric methods and half-lives of isotopes, unlike relative dating, which only arranges rocks in age order. Option b is correct.
The correct answer to the question is Absolute dating,' which utilizes the properties of atoms within rocks and other objects to accurately determine their ages. Absolute dating methods are based on radiometric dating, which involves measuring the rate of decay of unstable isotopes, such as uranium or argon, to estimate the precise age of rocks and fossils.
Radiometric dating relies on the concept of a half-life, which is defined as the time required for half of a sample of a radioactive isotope to decay into its daughter isotope. Using the known half-lives of various isotopes, scientists can calculate the age of a rock or fossil with precision. Unlike relative dating, which only provides a sequence or comparison of ages, absolute dating assigns a specific numerical age.
For instance, while relative dating can tell us that one layer of rock is older than another, absolute dating can establish that a rock is 150 million years old. This method is paramount in geology for constructing accurate timelines of Earth's history.

in your own words...How might scientist use geologic time to compare the age of two fossils? Describe the difference between biotic and abiotic parts of an ecosystem.
Answer:
Scientists observe the layers for evidence of similar rock types and fossil formations to determine the age of landforms. If they find the same fossil in two different locations, scientists may conclude that those fossils are most likely from the same time period.
Explanation:
Final answer:
Scientists use geologic time involving relative and absolute dating techniques to compare the age of fossils. Biotic components of an ecosystem are the living parts, while abiotic parts are non-living. The geologic time scale and geological principles help in understanding Earth's history and the development of life.
Explanation:
Scientists compare the age of two fossils by using geologic time, which involves both relative dating and absolute dating techniques. Relative dating places fossils and rocks in chronological order without determining their exact age. Scientists use index fossils and the principle of superposition to determine a relative age. Absolute dating, on the other hand, provides an approximate numerical age using radiometric techniques, such as measuring the decay of radioactive isotopes. However, the term "carbon dating" is somewhat of a misnomer when aging rocks and fossils, as this method is primarily used for dating items that are less than 50,000 years old, and not for older geologic materials.
In any ecosystem, the biotic components refer to the living parts, such as animals, plants, and microbes, while abiotic components include non-living factors like water, rocks, and climate. The interaction between these parts is crucial to the functioning of an ecosystem.

Vacuoles are found in both plant and animal cells, but they are larger in plant cells than in animal cells.
Explanation:The article is correct because although vacuoles are found in both plant and animal cells, they are larger in plant cells than in animal cells.
Plant cells have a large central vacuole that holds a mixture of water, nutrients, and wastes. A plant cell's vacuole can make up 90% of the cell's volume. In animal cells, vacuoles are much smaller.
In addition to containing most of the organelles found in animal cells, plant cells also have a cell wall, a large central vacuole, and plastids. These three features are not found in animal cells.
