A self-contained living thing

Given the decomposition reaction:2SI3(g)->2SO2(g) + O2(g)According to Le Châtelier’s principle, what will happen when the vol

kvasek [131]

To analyze the equilibrium and how it shifts aaccording to Le Châtelier’s principle, we have to see how the system reacts to the change.

The change is an increase in the volume of the container. Since all the compounds on equilibrium are in gaseous state, their volume is the same as its container, so an increase in the volume of the container increase the volume of the compounds.

The reactant is SI₃, but we have 2 of them for each reaction.

The products are 2 molecules of SO₂ and one molecule of O₂.

In total for each reaction, we have 2 molecules in the reactant part and 3 molecules in the product part.

Since they are all in gaseous form, this means that the products occupy more space than the reactants, that is, an increase in the volume will favor the products, because this increase will left more space for them to occupy.

Thinking in preassure, an increase in the volume will decrease pressure, because, by the Boyle's Law, they are inversely proportional (assuming ideal gas). Since there are more molecules per reaction on the products side, this will favor the products, since more molecules make more pressure and now it has been decreased.

Thus:

Increase in volume -> decrease in pressure -> favors the products.

This matches alternative B.

Write the acid-base reaction between the weak base ammonia NH3 and the strong acid hydrochloric acid HCL.

Fantom [35]

Answer:

HCl + NH₃ → NH₄⁺ + Cl⁻

Explanation:

When a strong acid as HCl reacts with a weak base as NH₃ a salt that comes from the conjugate acid, NH₄⁺, and the ion of the acid, Cl⁻, is produced as follows:

<em>This is the acid- base reaction</em>

The base captures the proton of the acid (proton aceptor) and the acid give the proton (Proton donor)

Automotive antifreeze consists of ethylene glycol, CH2(OH)CH2(OH), a nonvolatile nonelectrolyte. Calculate the boiling point and

spayn [35]

Answer:

Freezing point of solution = - 10.3°C

Boiling point of solution = 102.8°C

Explanation:

This is about colligative properties:

Freezing point depression → ΔT = Kf . m

ΔT = Freezing point of pure solvent - Freezing point of solution

Boiling point elevation → ΔT = Kb . m

ΔT = Boiling point of solution - Boiling point of pure solvent

Let's determine m which means molality (moles of solute in 1 kg of solvent)

Solute: Ethylene glycol → Mass = 25 g

Moles = Mass / Molar mass → 25 g / 60g/mol = 0.416 moles

Solvent: Water

25 % means, 25 g of solute in 100 g of solution

Therefore, the mass of water is 75 g (100 -25) . (Solution = Solute + Solvent)

We convert the mass from g to kg → 75 g . 1kg /1000g = 0.075 kg

Molality (mol/kg) = 0.416 m / 0.075kg = 5.55 m

We replace data in the formulas:

<u>Freezing point depression</u>:0° - Freezing point of solution= 1.86°C/m. 5.55 m

Freezing point of solution = - (1.86°C/m . 5.55m) = - 10.3°C

<u>Boiling point elevation</u>:Boiling point of solution - 100°C = 0.51°C /m . 5.55 m

Boiling point of solution = 0.51°C /m . 5.55 m + 100°C = 102.8°C

What might happen if the earth exceeds its carrying capacity

Yakvenalex [24]

If the earth was to exceed its weight the of people the population would then decrease because the environment couldnt sustain that many people the carbon would overwhelm oxygen......but its simply just a matter of natural resources (like food) more than anything else.
