how would you measure density of a rock
Use the D = M/V equation, in which Density can be found by dividing Mass/Volume.
To solve, first find a rectangular prism tub that is filled to a certain level. Next, place the rock inside to find the amount of displacement (or how high the water level goes up.) In this way, you can find the volume of the rock.
Next, solve for the Mass. This can be found by dividing the total weight from the gravitational pull. This would give you the mass.
Finally, to find Density, divide the Mass found with the Volume. This would give you your final answer

If a cube is split in half, the surface area of the pieces will be ___ that of the cube.
A. greater than
B. less than
C. the same as
D. none of these
If we are talking about BOTH the pieces surface areas the answer would be A. Greater than. This is because a split cube has an extra side on each piece that the original cube didn't have.
I hope that helps!!
If a cube is split in half, the surface area of the pieces will be greater than that of the cube.
If a cube is split in half, the surface area of the pieces will be greater than that of the cube. This is because when you cut the cube, you are adding two more faces (the cut faces), which increases the total surface area. Let's explore an example using a cube of side length 2 units:
Original cube surface area = 6 faces imes (2 units imes 2 units) = 24 square units.
When split, each half has 5 faces of 4 square units (original cube's faces) and 1 new face of 4 square units (from the cut), totaling 6 faces.
So, each half has a surface area of 6 faces imes 4 square units = 24 square units.
For both halves combined: 24 square units + 24 square units = 48 square units.
Comparing the original cube's surface area (24 square units) with the combined surface area of the two halves (48 square units), we can conclude that the surface area is increased after cutting the cube.
They lymphatic system’s function is to --------.
A) Transport fluid
B) Breathe
C) Digest food
D) Remove waste.
The correct answer is option A, that is, transport fluid.
The lymphatic system refers to a network of organs and tissues, which helps in getting rid of the body wastes, toxins, and other undesired elements. However, the main activity of the lymphatic system is to transport lymph, that is, a fluid comprising infection-fighting white blood cells, all through the body.
The lymphatic system mainly comprises of lymphatic vessels that are identical to the circulatory system's capillaries and veins. The vessels are associated with lymph nodes, where the filtration of lymph is done. The adenoids, tonsils, thymus, and spleen are all the components of the lymphatic system.
Give the electron configuration for the chloride ion. (please show the process!) =)
Answer:- [tex]1s^22s^22p^63s^23p^6[/tex]
Explanations:- Atomic number of chlrone(Cl) is 17 it means it has 17 electrons. It's electron configuration is: [tex]1s^22s^22p^63s^23p^5[/tex] .
Chloride ion is formed when Cl accepts one electron:
[tex]Cl+e^-\rightarrow Cl^-[/tex]
So, electrons for the chloride ion = 17+1 = 18
If we look at the electron configuration of Cl then 3p is still vacant as there are 5 electrons in it and it could have maximum 6 electrons. So, this 18th electron goes to 3p and the electron configuration of chloride ion becomes:
[tex]1s^22s^22p^63s^23p^6[/tex] .

Assuming no energy is transferred to or from the surroundings, calculate the final temperature, Tf, of the water after all the ice melts. heat capacity of h20(s) is 37.7j/kmol. heat capacity of h20(l) is 75.3j/kmol. enthalpy of fusion of h20 is 6.01j/kmol.
Answer:
10.3 °C
Step-by-step explanation:
This is an isolated system so
heat gained by ice + heat lost by water = 0
Heat to warm ice + heat to melt ice + heat to warm melt + heat lost by water = 0
q₁ + q₂ + q₃ + q₄ = 0
n₁C₁ΔT₁ + n₁ΔH_fus + n₁C₃ΔT₃ + n₄C₃ΔT₄ = 0
Step 1: Calculate q₁
n₁ = 40.0 g × 1/18.02
n₁ = 2.220 mol
C₁ = 37.7 J·K⁻¹mol⁻¹
ΔT₁ = T_f – T_i
ΔT₁ = 0.0 – (-15)
ΔT₁ = 15 °C = 15 K
q₁ = 2.220 × 37.7 × 15
q₁ = 1255 J
q₁ = 1.255 kJ
===============
Step 2. Calculate q₂
ΔH_fus = 6.01 kJ·mol⁻¹
q₂ = 2.220 × 6.01
q₂ = 13.34 kJ
===============
Step 3: Calculate q₃
C₃ = 75.3 J·K⁻¹mol⁻¹
ΔT₃ = T_f – T_i = x – 0 °C
ΔT₃ = x °C = x K
q₃ = 2.220 × 75.3 × x
q₃ = 167x J
q₃ = 0.167x kJ
===============
Step 4. Calculate q₄
n₄ = 265 × 1/18.02
n₄ = 14.71 mol
ΔT₄ = T_f – T_i = x – 25.0 °C
q₄ = 14.71 × 75.3 × (x – 25.0)
q₄ = 1107 × (x – 25.0)
q₄ = 1107x – 27 680 J
q₄ = 1.107x – 27.68 kJ
===============
Step 5. Solve for x
1.255 + 13.34 + 0.167x + 1.107x - 27.68 = 0
1.274x - 13.08 = 0
1.274x = 13.08
x = 13.08/1.274
x = 10.3 °C
The final temperature is -10.3 °C.

which of the following elements has the highest first ionization energy? strontium calcium magnesium or beryllium
Beryllium.
ExplanationAll four elements are found in the second column to the left of a periodic table. They are group 2 elements.
The 1st ionization energy generally decrease down each group.
Elements in each group have the same number of electrons in the outermost occupied electron shell. Electrons in the inner shell shield those in the outer shell from attractions from the nucleus, known as the shielding effect. The number of protons in each atom increase by more than 8 in each period. However, due to this effect, electrons in the outermost shell experience a far weaker force pulling them towards the center of the atom. For atoms of the four group 2 elements, electrons in the outermost layer would behave as if there's only two protons inside their nucleus. As a result, their end up with rather similar ionization energies.
Despite the same effective charge on each electron, the mean radius of the electrons increase down the group. Beryllium is in the second period; its electrons occupy only two electron shells in the ground state. On the contrary, strontium is in the fifth period; its electrons occupy up to five electrons shells in its ground state. The strength of electrostatic attraction decreases as the two charges move apart. As a result, outermost electrons in beryllium are way more attached to the nucleus than those in strontium.
FYI, the 1st ionization energy of the four elements are shown below:
Be: 899.50 kJ/molMg: 737.750 kJ/molCa: 589.830 kJ/molSr: 549.470 kJ/molThe element with the highest first ionization energy among the choices is; Beryllium, Be
The ionization energy of an element is the energy required to remove one of the electrons in its outermost shell.
The first ionization energy of elements is inversely proportional to the atomic radii of elements.
This is so because a lesser atomic radius corresponds to greater electrostatic attraction between the electron and the nucleus of the atom.
We must also state that the atomic radius of elements in the periodic table increases down a group and decreases across a period.
In essence, the smaller the atom of an element, the larger is its first ionization energy.
Strontium --Period 6, group 1Calcium --Period 4, group 2Magnesium --Period 3, group 2Beryllium -- period 2, group 2The element with the highest first ionization energy is the smallest element and is therefore Beryllium, Be.

1) What is the mole ratio of D to A in the generic chemical reaction? (2 points) Page 390 helps with understanding mole ratios. Be sure you’re only looking at the ratio of D to A. You can ignore B & C. 2A+ B C + 3D
Answer:- The mole ratio of D to A is 3:2.
Explanations:- Mole ratio for a chemical equation is the ratio of the coefficients of the molecules. Coefficients are the numbers used to balance the chemical equations.
For the given generic chemical equation, the coefficient of molecule A is 2 and the coefficient of D is 3. It means 2 molecules of A react with 3 molecules of D. So, the mole ratio of A to D is 2:3.
Since, we are asked about the mole ratio of D to A so we will write the coefficient of D first and hence the mole ratio of D to A is 3:2.

How many molecules of isopently acetate C7H1402 are released (1x10^ -6g) in a typical bee sting
The number of molecules of isopently acetate is 4.63 x 10¹⁵ molecules
calculation
Step 1: find the moles of isopently acetate( C₇H₁₄O₂)
moles = mass÷ molar mass
From periodic table the molar mass of C₇H₁₄O₂
= (12 x7 ) + (1 x14) +(16 x2) =130 g/mol
moles = 1 x10⁻⁶ g÷ 130 g/mol = 7 x 10⁻⁹ moles
step 2 ; use the Avogadro's law constant to calculate the number of molecules
That is according to Avogadro's law 1 mole = 6.02 x 10²³ molecules
7 x 10⁻⁹ moles = ? molecules
by cross multiplication
= { (7 x 10⁻⁹ moles x 6.02 x10²³ molecules) / 1 mole} = 4.63 x 10¹⁵ molecules
To determine the number of molecules of isoamyl acetate in a 1x10⁻⁶g bee sting, calculate the molar mass, convert mass to moles, and multiply by Avogadro's number to find approximately 4.625x10¹⁵ molecules.
To determine how many molecules of isoamyl acetate (isopentyl acetate) C₇H₁₄O₂ are released in 1x10⁻⁶g during a typical bee sting, we first need to calculate the molar mass of C₇H₁₄O₂. The molar mass is given by the sum of the atomic masses of all the atoms in one molecule of the substance. This is calculated as:
7 carbons (C) times 12.01 g/mol = 84.07 g/mol
14 hydrogens (H) times 1.008 g/mol = 14.112 g/mol
2 oxygens (O) times 16.00 g/mol = 32.00 g/mol
Adding these together gives a molar mass of 130.182 g/mol for isoamyl acetate.
Next, we use the following formula to convert the mass of the substance to moles:
moles = mass (g) / molar mass (g/mol)
= 1x10⁻⁶g / 130.182 g/mol
moles = 7.68x10⁻⁹ moles of C₇H₁₄O₂.
Finally, to find the number of molecules, we multiply the moles of the substance by Avogadro's number (6.022x10²³ molecules/mol):
number of molecules = 7.68x10⁻⁹ moles x 6.022x10²³ molecules/mol
number of molecules = 4.625x10¹⁵ molecules of C₇H₁₄O₂.
The number of molecules of isoamyl acetate released in 1x10⁻⁶g during a typical bee sting is approximately 4.625x10¹⁵.

Molar Mass information: Iron = 55.8 g/mol, Oxygen= 15.9 g/mol
The grams of Fe₂O₃ that are formed is 47.68 g
calculation
Step 1: write the equation for reaction
4 Fe +3O₂ → 2 Fe₂O₃
Step 2: find the moles of Fe
moles = mass÷ molar mass

Step 4 : find the mass of Fe₂O₃
mass = mass x molar mass
The molar mass of Fe₂O₃ = (55.8 x 2 +(15.9 x3) = 159.3 g/mol

Differentiate crystalline and amorphous solid
Crystalline solids have a highly ordered, regular structure and distinct melting points. Amorphous solids have randomly arranged particles and melt over a range of temperatures. They're both used extensively in technology.
Explanation:The primary difference between crystalline and amorphous solids lies in their internal atomic structure. Crystalline solids have their atoms, ions, or molecules arranged in a regular, repeating pattern, forming a lattice. They also have distinct melting temperatures due to the identical attractions their particles experience. Examples of crystalline solids include ionic solids, metallic solids, covalent network solids, and molecular solids.
On the other hand, amorphous solids do not have a well-ordered internal structure. Their particles are arranged randomly, and they soften and melt over a range of temperatures due to the range of interactions their particles experience. Examples of amorphous solids include glasses and certain plastics.
Both types of solids are used extensively in technology, like the silicon crystals in computer chips (a crystalline solid) or the glass in a smartphone screen (an amorphous solid).

Correct question is: How many milliliters of C₅H₈ can be made from 366 mL C₅H₁₂ ?
density of C₅H₁₂ = 0.620 g/mL
density of C₅H₈ = 0.681 g/mL
density of H₂ = 0.0899g/L
if a and b are inversely proportional and the value of a becomes 3 times as big what happens to b
Answer: 3 times lesser
a and b are inversely proportional,
a ∝ (1/b)
or a = k/b where k =constant ,
if a is 3 times increased what happens to b ?
b is 3 times less.
