6 0

The chemical formula of a compound express the atoms by which the molecule is formed and the ratio of the atoms in which they are combined.

The space filling model of a compound describe the electron density in the compound of each atom.

The ball and stick arrangement of a compound describe the way in which the molecules are present in three dimensions.

The structural formula state the number of atoms present in the molecule, the type of element or atom present in the molecule and the way in which they are arranged closely which is the bond.

Thus only the structural formula only will cover all the options as stated.

Calcium chloride is added to the roadways after a snowstorm. Which colligative property is being showcased here?
vlabodo [156]

Answer:

Option (D) freezing point depression

Explanation:

Calcium chloride is added to the roadways after a snowstorm because it reduces the freezing point of the ice. Further more, it has been observed that the calcium chloride also produces enough heat which enhances the melting of the ice as it produces an exothermic reaction.

If 0.500 mol of each of the following solutes is dissolved in 2.0 L of water, which will cause the greatest increase in the boil
serious [3.7K]

Answer is: D. Na2SO4.

b(solution) = 0.500 mol ÷ 2.0 L.

b(solution) = 0.250 mol/L.

b(solution) = 0.250 m; molality of the solutions.

ΔT = Kf · b(solution) · i.

Kf - the freezing point depression constant.

i - Van 't Hoff factor.

Dissociation of sodium sulfate in water: Na₂SO₄(aq) → 2Na⁺(aq) + SO₄²⁻(aq).

Sodium sulfate dissociates on sodium cations and sulfate anion, sodium sulfate has approximately i = 3.

Sodium chloride (NaCl) and potassium iodide (KI) have Van 't Hoff factor approximately i = 2.

Carbon dioxide (CO₂) has covalent bonds (i = 1, do not dissociate on ions).

Because molality and the freezing point depression constant are constant, greatest freezing point lowering is solution with highest Van 't Hoff factor.

If the bag was made from a metal (like sturdy aluminum foil), do you think it would lose its heat faster or slower than the plas
Luden [163]

I think it would lose its heat faster than the plastic bags because of higher conductivity feature.

<h3>What is conduction?</h3>

Conduction is the process in which heat or electricity is transmitted or transferred through the material of a substance without movement of the material.

We know that metals are good conductors so we can conclude that it would lose its heat faster than the plastic bags bof higher conductivity feature.

what was the initial pressure of 14.8 mL of gas at 75.5 C , when it occupied a volume of 16.5 mL at 70.2 C and 101.3 kPa?
OLEGan [10]

Answer:

1038.96 kPa

Explanation:

We’ll use the ideal gas law; P1V1/T1 = P2V2/T2

P1*14.8/75.5 = 101.3*16.5/70.2

P1 = (101.3 * 16.5 * 75.5) / (70.2 *14.8)

P1 = 1038.96
