10. Which would make the best aquifer?

Chemistry
1 answer:
Levart [38]3 years ago
6 0

c. sandstone in the zone of saturation

Explanation:

The best aquifer of all is a sandstone in the zone of saturation. An aquifer is a porous and permeable formation where groundwater can accumulate.

  • To be a good aquifer, a rock or soil must be porous and permeable.
  • Porosity is the amount of void spaces present in a rock.
  • Permeability is the inter-connectivity of the pore spaces.

The zone of saturation is the zone below the water table where water is always present underground.

  • Sandstones have high porosity and permeability.
  • They are good aquifers when found at the zone of saturation.

OOH! I know photosynthesis and I have been doing it in school. So the Glucose and oxygen combine to help make the photosynthesis AND it is so important to not forget about Carbon Dioxide and all the features for that because a plant needs carbon dioxide while we need oxygen and plants give out oxygen so that humans can have it and we breathe out carbon dioxide so that plants can have it. We pretty much just help each other out. I plants weren't there than humans wouldn't be there. Hope this helps!

Diazomethane has the following composition by mass: 28.57% C, 4.80% H, and 66.64% N. The molar mass of diazomethane is 42.04 g/m
Alex777 [14]

Answer:

CH2N2

Explanation:

To find the molecular formula, we must first find the empirical formula as follows:

28.57% C - 28.57g of Carbon

4.80% H - 4.80g of Hydrogen

66.64% N - 66.64g of Nitrogen

Next, we convert this mass values to mole by dividing by their respective atomic mass.

C = 28.57/12 = 2.38mol

H = 4.80/1 = 4.80mol

N = 66.64/14 = 4.76mol

Next, we divide each mole value by the smallest mole value (2.38mol)

C = 2.38mol ÷ 2.38 = 1

H = 4.80mol ÷ 2.38 = 2.01

N = 4.76mol ÷ 2.38 = 2

The empirical ratio of C, H and N is therefore 1:2:2. Hence, the empirical formula is CH2N2

To calculate the molecular formula;

(CH2N2)n = 42.04 g/mol

{12 + 1(2) + 14(2)}n = 42.04

{12 + 2 + 28}n = 42.04

{42}n = 42.04

n = 42.04/42

n = 1.00009

Since n = 1, molecular formula is CH2N2

Which statement about the temperatures of phase changes and electrostatic forces holding the molecules is correct?(1 point)
lubasha [3.4K]

The temperature at which phase changes occur is highly dependent on the electrostatic forces between the molecules in the substance.

The forces that hold molecules together are called intermolecular forces. These intermolecular forces affect the temperature at which phase changes occur. The  statement about phase changes and electrostatic forces that is correct is that; "the temperatures at which a substance changes phases indicate the relative strength of the forces between molecules in the substance."

There are three states of matter, solid liquid and gas. The order of intermolecular forces in all the states of matter are not the same. The order of strongest collective electrostatic forces to weakest collective electrostatic forces is; solid, liquid, gas.

When water boils, the forces between water molecules break, and the bonds between the atoms in water are unchanged.

When a sample of calcium carbonate is cooled, the forces strengthen, and the molecule structure becomes more rigid.

If the boiling point of acetone is lower than the boiling point of ethanol, then, the intermolecular forces in ethanol are stronger than the intermolecular forces in acetone.
