Question

balance the equation Ca +H2O =Ca(OH) + H​

Answer 1

Ca+H2O---->Ca(OH)2+H2

Answer 2

HELLO DEAR FRIEND

Ca + H2O --> Ca(OH) + H

REACTANT SIDE =====

Calcium (Ca) => 1

Hydrogen (H) => 2

Oxygen (O) => 1

PRODUCT SIDE =====

Calcium (Ca) => 1

Hydrogen (H) => 2

Oxygen => 1

SO, HERE WE CAN SEE THAT ACCORDING TO LAW OF CONSERVATION OF MASS NUMBER OF ATOMS OF THE ELEMENTS ARE EQUAL TO THE NUMBER OF ATOMS OF THE RESPECTIVE ELEMENTS ARE EQUAL.

SO, IT IS ALREADY BALANCED.

Ca + H2O => Ca(OH) + H

HOPE IT HELPS
