Given the equation Ca + H2O --> Ca(OH)2 + H2 how many grams of calcium will react completely with 10.0 grams of water? *

11.0 g of calcium will react with 10.0 grams of water.

Explanation:

To calculate the moles, we use the equation:

moles of

The balanced chemical equation is:

According to stoichiometry :

2 moles of require = 1 mole of

Thus 0.55 moles of require=  of  

Mass of

Thus 11.0 g of calcium will react with 10.0 grams of water.
