Calculating the total volume we get:

v(total)= v2 - v1

v(total)= 60.7 ml - 50.0 ml

v(total)= 10.7 ml

Applying the density formula, we get:

d = m/v

d = 30.73 g/ 10.7 ml

d = 2.87 g/ml

Centrifugal force (centripetal acceleration) is used with a centrifuge to rapidly separate the precipitate from the liquid.

What is a centrifuge?

According to particle size and density, medium viscosity, and rotor speed, particles suspended in a liquid are separated using a centrifuge. Gravitational forces within a solution cause particles with densities greater than the solvent to sink and those with densities less than the solvent to float to the top.

Using the centrifugal force to separate particles found in a solution, centrifugation is a mechanical technique for separation. Depending on the size, shape, density, and rotor speed of the particles, different groups are created.

The mass of ammonia is 68.74 grams.

Balanced chemical equation for reaction of ammonia and oxygen:

4NH₃ + 7O₂ → 4NO₂ + 6H₂O

m(NO₂) = 125 g; the mass of nitrogen(IV) oxide

n(NO₂) = m(NO₂) ÷ M(NO₂)

n(NO₂) = 125 g ÷ 46 g/mol

n(NO₂) = 2.72 mol; amount of nitrogen(IV) oxide

From the chemical equation: n(NO₂) : n(NH₃) = 1 : 1

n(NH₃) = 2.72 mol

the percentage yield = 67.2% ÷ 100%

the percentage yield = 0.672

m(NH₃) = n(NH₃) × M(NH₃) ÷ the percentage yield

m(NH₃) = 2.72 mol × 17 g/mol ÷ 0.672

Explanation:

C) increase body's awareness of the stress response

The function of the general adaptation syndrome (GAS) is to:

d) Change the body's response to stress.

The general adaptation syndrome (GAS) is a three-stage model that describes how the body responds to stress. The first stage is the alarm reaction, which is when the body releases hormones such as cortisol and adrenaline in response to a perceived threat. The second stage is the resistance stage, which is when the body tries to adapt to the stressor. The third stage is the exhaustion stage, which is when the body's resources are depleted and it can no longer cope with the stressor.

The function of GAS is to change the body's response to stress so that it can better cope with future stressors. This is done by increasing the production of stress hormones, such as cortisol, and by increasing the body's ability to use glucose for energy.

So the answer is (d) Change the body's response to stress.

Explanation:

Solutions are mixtures that are homogeneous while suspensions are mixtures that are heterogeneous.

A gaseous mixture of O₂ and N₂ that contains 38.8% nitrogen by mass, with the total pressure of 465 mmHg, has a partial pressure of oxygen of 270 mmHg.

The total pressure of an ideal gas mixture is the sum of the partial pressures of the gases in the mixture.

total pressure = 465 mmHg

m(N₂) = 38.8 g; mass of the nitrogen

n(N₂) = m(N₂) ÷ M(N₂)

n(N₂) = 38.8 g ÷ 28 g/mol

n(N₂) = 1.385 mol; amount og nitrogen gas

m(O₂) = 61.2 g; mass of oxygen gas

n(O₂) = m(O₂) ÷ M(O₂)

n(O₂) = 61.2 g ÷ 32 g/mol.

n(O₂) = 1.9125 mol; amount of oxygen gas

Using Dalton's law:

p(O₂) = (1.912 mol / 1.912 mol + 1.385 mol) × 465 mmHg

p(O₂) = 270 mmHg; pressure of the oxygen gas

Ionic compounds dissolve in water because the water molecules hydrate the ions.

Explanation:

To dissolve an ionic compound, the water molecules must be able to stabilize the ions that result from breaking the ionic bond.

They do this by hydrating the ions.

Water is a polar molecule. It has a permanent dipole.

The

O

atom has a partial negative charge, and the

H

atoms have a partial positive charge.

When an ionic compound is added to water, the anion is attracted to partially positive hydrogen atom of water and cation is attracted to partially negative oxygen atom of water.

Ionic compound or electrovalent compound is a type of compound  which is formed between the  two elements when there is an exchange of electrons which takes place between  the atoms resulting in the formation of ions.

When the atom looses an electron it develops a positive charge and forms an ion called the cation while the other atom gains the electron and develops a negative charge  and forms an ion called the anion.

As the two atoms are oppositely charged they attract each other which results in the formation of a bond called the ionic bond.

In the preparatory phase of glycolysis, two molecules of ATP are invested and the hexose chain is cleaved into two triose phosphates. During this, the phosphorylation of glucose and its conversion to glyceraldehyde-3-phosphate take place.  During this phase, the conversion of glyceraldehyde-3-phosphate to pyruvate and the coupled formation of ATP take place. Because Glucose is split to yield two molecules of D-Glyceraldehyde-3-phosphate, each step in the payoff phase occurs twice per molecule of glucose.

The mass of oxygen required to react with calcium to produce 44.8 g of calcium oxide is 12.79 grams.

The reaction between Calcium and Oxygen produces calcium oxide which is represented as

2Ca + O2 = 2CaO

According to the above reaction

1 mole of O2 produces 2 moles of CaO

Or 112 grams of CaO is produced by 32 grams of O2

1 gram of CaO is produced by 32/112 grams of O2

Hence 44.8 g of CaO is produced by 32/112 x 44.8 = 12.79 grams of O2

Therefore, the mass of oxygen required to react with calcium to produce 44.8 g of calcium oxide is 12.79 grams.
