<h3>Answer:</h3>

H₂O

<h3>Explanation:</h3>

The additional product that balances the reaction is water (H₂O).

  • Therefore, the complete balanced equation for the reaction is;

H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + H₂O(l)

  • Balancing a chemical equation ensures that the law of conservation of mass is obeyed by the reaction.
  • The reaction is an example of a neutralization reaction where an acid, H₂SO₄, reacts with a base, NaOH to form a salt and water.
  • In this case the salt formed is sodium sulfate (Na₂SO₄)

If 3.0 liters of oxygen gas react with excess carbon monoxide at STP, how many liters of carbon dioxide can be produced under th
mr_godi [17]

Answer:

The volume of CO2 produced is 6.0 L (option D)

Explanation:

Step 1: Data given

Volume of oxygen = 3.0 L

Carbon monoxide = CO = in excess

Step 2: The balanced equation

2 CO (g) + O2 (g) → 2 CO2 (g)

Step 3: Calculate moles of O2

1 mol of gas at STP = 22.4 L

3.0 L = 0.134 moles

Step 3: Calculate moles of CO2

For 2 moles CO we need 1 mol of O2 to produce 2 moles of CO2

For 0.134 moles O2 we'll have 2*0.134 = 0.268 moles CO2

Step 4: Calculate volume of CO2

1 mol = 22.4 L

0.268 mol = 22.4 * 0.268 = 6.0 L

The volume of CO2 produced is 6.0 L
