when 1.57 molmol o2o2 reacts with h2h2 to form h2oh2o , how many moles of h2 are consumed in the process?

Answer :

Final answer:

For the formation of water from hydrogen and oxygen, 2 moles of hydrogen are needed for every 1 mole of oxygen. Therefore, if 1.57 moles of oxygen are used, 3.14 moles of hydrogen will be consumed.

Explanation:

The balanced equation for the formation of water (H2O) from hydrogen (H2) and oxygen (O2) is:
2H2 + O2 → 2H2O

This equation tells us that 2 moles of hydrogen react with 1 mole of oxygen to form 2 moles of water. Therefore, if 1.57 moles of oxygen are used, this will react with twice as many moles of hydrogen. Calculating 1.57 * 2 gives us 3.14 moles of hydrogen.
