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.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
