<u>Answer:</u>

Option(A)

The container contains 12 grams of water and no ice

<u>Explanation:</u>

When the student kept the ice in the container, the ice starts to melt as the air temperature around the ice is warmer than the temperature of the ice itself.

The solid particles in the ice absorbs the heat from the air, allowing the particles in the ice to move freely. Hence, melting takes place and the student finds water and no ice in the container.

Shkiper50 [21]

Answer:

1. Percentage composition of: Na = 42%; P = 19.0%; O = 39%

2. Simplest formula of compound is PbO₂

3. (i) 2Cu(NO₃) ---> 2CuO + 2NO₂ + 3O₂

(ii) 2C₂H₆ + 7O₂ ---> 4CO₂ + 6H₂O

(iii) Mg₃N₂ + 6H₂O ---> 3Mg(OH)₂ + 2NH₃

4. 48 g of MG will react with 2 moles of Cl₂

5. 0.288 g of SO2 will be  produced from the combustion of 0.331 g P₄S₃ in excess O₂

6. 12.8 g of nitric oxide can be produced from the reaction of 8.00 g NH₃ with 17.0 g O₂

From the following enthalpy changes,
AfilCa [17]

Answer:

∆H = -763kJ

Explanation:

Using Hess's law we can determine the ΔH of a reaction from the sum of similar reactions. Using the reactions:

<em>(1) </em>2PCl3(l) → 2P(s) + 3Cl2(g) ∆H = -640 kJ

<em>(2) </em>2P(s) + 5Cl2(g) → 2PCl5(s) ∆H = -886 kJ

The sum of (1)/2 + (2)/2 gives:

(1) / 2 = PCl3(l) → P(s) + 3/2Cl2(g) ∆H = -640 kJ/2 = -320kJ

(2) / 2 = P(s) + 5/2Cl2(g) → PCl5(s) ∆H = -886 kJ/2 = -443kJ

PCl3(l) + Cl2(g) → PCl5(s) ∆H = -320kJ - 443kJ =

<h3>∆H = -763kJ </h3>
