Answer:

The amount of moles of CO₂ is 0.026 moles

Explanation:

An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

The equation known as the ideal gas equation explains the relationship between the four variables P (Pressure), V (Volume), T (Temperature) and n (Amount of substance). The ideal gas law is expressed mathematically as:

P*V = n*R*T

where P represents the pressure of the gas, V its volume, n the number of moles of gas (which must remain constant), R the constant of the gases and T the temperature of the gas.

In this case:

Replacing:

855 mmHg*0.475 L=n*62.36367 [tex]\frac{mmHg*L}{mol*K}[/tex] *251 °K

Solving:

[tex]n=\frac{855 mmHg*0.475 L}{62.36367 \frac{mmHg*L}{mol*K} *251 K}[/tex]

n= 0.026 moles

Answer:

1. molar mass of h2co3: 62.03 g

2. total molar mass for hydrogen atoms: 2.02 g

3. total molar mass for carbon atoms: 12.01 g

4. total molar mass for oxygen atoms: 48.00 g

5. hydrogen percent composition: 3.3%

6. oxygen percent composition: 77.4%

Explanation:

1. 1.01+1.01+12.01+16.00+16.00+16.00= 62.03

2. 1.01×2= 2.02

3. 12.01×1= 12.01

4. 16.00×3= 48.00

5. (2.02/62.03)×100= 3.3%

6. (48.00/62.03)×100= 77.4%

The molar mass of H2CO3 is 62.03 g/mol. The hydrogen percent composition in H2CO3 is 3.25% and the oxygen percent composition is 77.36%.

The molar mass of H2CO3 can be calculated by adding the molar masses of hydrogen (H), carbon (C), and oxygen (O) in the compound. The molar mass of hydrogen is 1.008 g/mol, the molar mass of carbon is 12.01 g/mol, and the molar mass of oxygen is 16.00 g/mol. Therefore, the molar mass of H2CO3 is: (2 x 1.008) + 12.01 + (3 x 16.00) = 62.03 g/mol.

The total molar mass for hydrogen atoms in H2CO3 is 2 x 1.008 = 2.016 g/mol.

The total molar mass for carbon atoms in H2CO3 is 12.01 g/mol.

The total molar mass for oxygen atoms in H2CO3 is 3 x 16.00 = 48.00 g/mol.

The hydrogen percent composition in H2CO3 can be calculated by dividing the molar mass of hydrogen by the molar mass of H2CO3 and multiplying by 100. Therefore, the hydrogen percent composition in H2CO3 is: (2.016 / 62.03) x 100 = 3.25%.

The oxygen percent composition in H2CO3 can be calculated by dividing the molar mass of oxygen by the molar mass of H2CO3 and multiplying by 100. Therefore, the oxygen percent composition in H2CO3 is: (48.00 / 62.03) x 100 = 77.36%.

Answer:

2.8M

Explanation:

The following data were obtained from the question:

Volume of stock solution (V1) = 40mL

Molarity of the stock solution (M1) = 7M

Volume of diluted solution (V2) = 100mL

Molarity of diluted solution (M2) =?

Using the dilution formula, we can easily find the molarity of the diluted solution as follow:

M1V1 = M2V2

7 x 40 = M2 x 100

Divide both side by 100

M2 = (7 x 40)/100

M2 = 2.8M

Therefore, the molarity of the diluted solution is 2.8M

Answer:

A. H2 is the limiting reactant.

B. The greatest mole of NH3 produced is 4.6 moles

C. The excess reactant is N2 and the leftover mole is 2.4 moles

Explanation:

The balanced equation for the reaction is given below:

N2 + 3H2 —> 2NH3

To obtain the greatest amount of NH3 that can be formed from the reaction of 4.7 mol of N2 and 6.9 mol of H2, we must first determine the limiting reactant.

A. Determination of the limiting reactant.

This is illustrated below:

From the balanced equation above,

1 mole of N2 reacted with 3 moles of H2.

Therefore, 4.7 moles of N2 will react with = 4.7 x 3 = 14.1 moles of H2.

We can see from the calculations made above, that it will take a higher amount i.e 14.1 moles of H2 than 6.9 moles given to react with 4.7 moles of N2.

Therefore, H2 is the limiting reactant and N2 is the excess reactant.

B. Determination of the greatest amount of NH3 from the reaction.

The limiting reactant is always used to obtain the maximum yield of any reaction as all of it is used in the reaction. The limiting reactant for the above reaction is H2 and the greatest amount of NH3 is obtained as follow:

From the balanced equation above,

3 moles of H2 reacted to produce 2 moles of NH3.

Therefore, 6.9 moles of H2 will react to produce = (6.9 x 2)/3 = 4.6 moles of NH3.

The greatest amount of NH3 produced is 4.6 moles

C. Determination of the moles of excess reactant that is leftover after the reaction.

This is illustrated below:

From the balanced equation above,

1 mole of N2 reacted with 3 moles of H2.

Therefore, Xmol of N2 will react with 6.9 moles of H2 i.e

Xmol of N2 = 6.9/3

Xmol of N2 = 2.3 moles

Therefore, 2.3 moles N2 reacted

The leftover mole of N2 is obtained as follow:

Mole of N2 given = 4.7 moles

Mole of N2 that react = 2.3 moles

Leftover mole of N2 =.?

Leftover mole of N2 = (Mole of N2 given) – (Mole of N2 that react)

Leftover mole of N2 = 4.7 – 2.3

Leftover mole of N2 = 2.4 moles

Explanation:

Edge

The hydrogen ion concentration of these two solutions differs from each other by a factor of 10.

The amount of solute that has been dissolved in a specific volume of solvent or solution is measured by the solution's concentration. A solution that contains a significant amount of dissolved solute is said to be concentrated.

You can determine how much solute has been dissolved in the solvent by looking at the concentration of the solution. For instance, the concentration could be stated as 1 teaspoon of salt per 2 cups of water if you add 1 teaspoon to 2 cups of water.

The negative logarithm of the concentration of hydrogen ions in an aqueous solution is used to represent the relationship between the two, which is why the name pH is defined as the power of hydrogen.

Thus, the two solutions differ from each other by a factor of 10.

Answer:

Option D - 10,000 years ago in the Middle East

The primary difference between an amoeba and a plant is that the amoeba is unicellular, meaning it consists of a single cell, whereas a plant is multicellular and has many cells that form tissues and organs. Option B is correct.

The main difference between an amoeba and a plant is how they obtain their nutrients. The choice from the provided question options that correctly identifies the primary difference is: The amoeba contains only one cell.

An amoeba is a type of unicellular organism which means it consists of a single cell, while a plant is multicellular and consists of many cells that are organized into tissues and organs. Amoebas consume their food by engulfing it through a process called endocytosis, using the food as a material source and an energy source.

In contrast, plants produce their own food through a process called photosynthesis, using sunlight to convert carbon dioxide and water into sugars and oxygen. Photosynthesis mainly occurs in the leaves of plants where cells contain chloroplasts, which are specialized organelles for this process.

Answer:

24 moles

Explanation:

Based on the reaction:

Sn + 2HF → SnF₂ + H₂

1 mole of Sn and 2 moles of HF produce 1 mole of both SnF₂ and H₂.

48g of H₂ -molar mass 2.0g/mol- are:

48g × (1mol / 2.0g) = 24 moles of H₂

As 1 mole of SnF₂ is produced with 1 mole of H₂ and moles of H₂ produced were 24moles, moles of SnF₂ are 24 moles, too.

Answer:

protons are positive neutron are neutral and electrons are negative.

Explanation:

Answer:

A proton is a subatomic particle, symbol p or p⁺ , with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are collectively referred to as "nucleons".

a neutron is a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.

a electron is a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.

Cells that contain half of the number of chromosomes present in the parent cell.

Explanation:

Meiosis is a type of cell division necessary for sexual reproduction. Meiosis produces four cells that contain half of the number of chromosomes present in the parent cell.

Final answer:

Meiosis produces four haploid daughter cells with half the number of chromosomes as the parent cell, which, in humans, results in cells with 23 chromosomes.

Explanation:

The process of meiosis results in the production of gametes, which are sex cells like eggs and sperm. During this intricate process of cell division, DNA is copied once, and then the cell divides twice, ultimately producing four daughter cells that each contain half the number of chromosomes as the original parent cell. In humans, for instance, where the parent cell contains 46 chromosomes, meiosis results in daughter cells with only 23 chromosomes.

These cells are termed haploid, compared to the diploid state of the original parent cell, which contains two sets of chromosomes. As a result, the correct answer to the student's question is option (d): Cells that contain half of the number of chromosomes present in the parent cell.

Two ecosystems might have different species of plant this is as a result of the nature of the ecosystem and the ability of plants to thrive in them.

Explanation:

An ecosystem can be defined as a community of organisms living together and interacting with their physical environment. There are different types of ecosystems but they are all categorized under terrestrial and aquatic habitats. They include forests, grasslands, deserts, freshwater and marine.

In the desert ecosystem an example of a plant that grows there is the cactus plant, this is as a result of their ability to conserve water.

In freshwater ecosystem, an example of a plant found there is the waterlily this is due to their unique ability to survive on water surfaces.

These different plant species are affected by different limiting factors in their ecosystems such as temperature, sunlight, nutrients.

B-changes occur gradually

Explanation:

"Changes occur gradually" is the sentence that belongs in the area shown by the X. Primary succession takes place in environments devoid of life, such as freshly created volcanic islands.

Secondary succession happens in places where there was once life, such after a fire. Both situations involve gradual changes as various species colonise the environment. Lichens, which can endure harsh circumstances, first colonise the environment as the first stage of primary succession.

Other species begin to colonise the area as it gets more favourable, which encourages the growth of a more diversified ecosystem. It may take decades or perhaps millennia to finish this procedure.

After a disturbance, such a fire, which wipes out the old ecosystem, secondary succession starts. As The number of species gradually rises as the ecosystem heals and species from the surrounding areas repopulate the region. However, in some instances, competition or other factors may result in a decrease in the number of species.

Therefore, the statement that belongs in the region marked X is "changes occur gradually", as this is true for both primary and secondary successions.

Lenses form images by refracting light, whereas mirrors form images by reflecting it. Lenses bend and converge light rays to a focal point to create an image, in contrast to mirrors which reflect light to form an image.

The statement that best describes the difference between how lenses and mirrors interact with light is that lenses form images by refracting light, whereas mirrors do not. When parallel rays of light pass through a lens, they are refracted, or bent, in such a way that they converge at a focal point, forming an image. In contrast, mirrors form images by reflecting light, using the law of reflection to redirect light rays at specific angles, allowing mirrors to create images as well.
