Balanced equation:
Pb(SO₄)₂ + 2 Zn → 2 ZnSO₄ + Pb
From the equation we found that 2 moles of Zn form 2 moles of ZnSO₄ 
so 0.582 mole of Zn will produce 0.582 ZnSO₄
Molar mass of ZnSO₄ = 161.47 g/mole
Mass of ZnSO₄ formed = 161.47 x 0.582 = 94.0 grams

The combustion of propane (C3H8) produces CO₂ and H₂O:
fomenos

Answer:

4.4 moles of water

Explanation:

Propane is C3H8. Is the chemical equation, you wrote C2H8 which is wrong. Type everything properly and give a check before finally posting the question.

The chemical equation that is given, is not properly balanced. The BALANCED equation would be

C3H8 + 5O2 → 3CO2 + 4H2O

From this balanced chemical equation, we see that 5 moles of oxygen produce 4 moles of water.

5 moles of Oxygen → 4 moles of water

1mole of oxygen → \frac{4}{5} moles of water

5.5 moles of oxygen → (\frac{4}{5} × 5.5) moles of water = 4.4 moles of water

∴ The reaction of 5.5 mol of O2 will produce <u>4.4</u> mol of H2O. [Answer:]

Aqueous sulfuric acid reacts with solid sodium hydroxide to produce aqueous sodium sulfate and liquid water. If 1.92 g of sodium
Oksana_A [137]

Answer:

The % yield is 27.0 %

Explanation:

<u>Step 1: </u>Data given

Mass of sulfuric acid = 4.9 grams

Mass of sodium hydroxide = 7.8 grams

Mass of sodium sulfate produced = 1.92 grams

Molar mass H2SO4 = 98.08 g/mol

Molar mass NaOH = 40 g/mol

Molar mass Na2SO4 = 142.04 g/mol

<u>Step 2: </u>The balanced equation

H2SO4 + 2NaOH → Na2SO4 + 2H2O

<u>Step 3</u>: Calculate moles H2SO4

Moles H2SO4 = Mass H2SO4 / Molar mass H2SO4

Moles H2SO4 = 4.9 grams / 98.08 g/mol =

Moles H2SO4 = 0.05 moles

<u>Step 4:</u> Calculate moles NaOH

Moles NaOH = 7.8 grams / 40 g/mol

Moles NaOH = 0.195 moles

<u>Step 5</u>: Calculate limiting reactant

For 1 mole H2SO4 consumed ,we need 2 moles NaOH to produce 1 mole Na2SO4 and 2 moles H2O

H2SO4 is the limiting reactant. It will completely be consumed (0.05 moles).

NaOH is in excess. There will react 2*0.05 = 0.1 moles

There will remain 0.195 -0.1 = 0.095 moles NaOH

<u>Step 6:</u> Calculate moles Na2SO4

For 1 mole H2SO4 consumed ,we need 2 moles NaOH to produce 1 mole Na2SO4

For 0.05 moles H2SO4, we have 0.05 moles Na2SO4

<u>Step 7:</u> Calculate mass of Na2SO4

Mass Na2SO4 = Moles Na2SO4 * Molar mass Na2SO4

Mass = 0.05 moles * 142.04 g/mol = 7.102

This is the theoretical yield

<u>Step 8:</u> Calculate the percent yield of Na2SO4

% yield = (actual yield / theoretical yield) * 100%

% yield = (1.92 /  7.102) *100% = 27.0 %

The % yield is 27.0 %
