Question: How many moles of NaOH are produced when 2 moles of Na react with 2 moles of water?

Options:

Correct Answer: 2 moles

Solution:

2Na + 2H2O → 2NaOH. Therefore, 2 moles of Na produce 2 moles of NaOH.

How many moles of NaOH are produced when 2 moles of Na react with 2 moles of water?

How many moles of NaOH are produced when 2 moles of Na react with 2 moles of water?

Step 1: Identify the reactants in the reaction. Here, we have sodium (Na) and water (H2O).
Step 2: Write down the balanced chemical equation for the reaction. The equation is 2Na + 2H2O → 2NaOH.
Step 3: Look at the coefficients in the balanced equation. They tell us the ratio of reactants to products.
Step 4: Notice that for every 2 moles of Na that react, 2 moles of NaOH are produced.
Step 5: Since we start with 2 moles of Na, we can conclude that 2 moles of Na will produce 2 moles of NaOH.
