40 g / 56 g X 100%
The percent composition of calcium oxide (CaO) is 71.5% calcium (Ca) and 28.5% oxygen (O).
40 g / 56 g X 100%
calcium + oxygen --> calcium oxide Ca + O --> CaO
how do you write a balanced chemical formula for this question CaO + H2O ---> Ca(OH)2
The balanced symbol equation for calcium oxide (CaO) with water (H2O) forming calcium hydroxide (Ca(OH)2) is: CaO + H2O → Ca(OH)2
The percent composition of calcium oxide (CaO) is 71.5% calcium (Ca) and 28.5% oxygen (O).
It would seem that because calcium and oxygen are in equal molar ratio for this compound that it would be 50 percent. But that is incorrect, because they each have differing molar masses. Oxygen has a molar mass of 16.000 and calcium has a molar mass of 40.078. So calcium is 40.078/56.078, which is 71.47 percent.

'CaO' ; 1 x atom of calcium (Ca) 1 x atom of oxygen (O).
The balanced symbol equation for calcium oxide (CaO) with water (H2O) forming calcium hydroxide (Ca(OH)2) is: CaO + H2O → Ca(OH)2
CaO ; 1 atom of Calcium (Ca) 1 atom of oxygen (O)
The percent composition by element of Ca(C2H3O2)2 is calcium 25.339%, hydrogen 3.824%, carbon 30.375%, and oxygen 40.462%.
The balanced equation for the reaction between calcium oxide (CaO) and water (H2O) is: CaO + H2O -> Ca(OH)2. This reaction produces calcium hydroxide (Ca(OH)2) as the product.
