40 g / 56 g X 100%
40g/56g x 100%
= 71.43 % - APEX
40 g / 56 g X 100%
CaO ; 1 atom of Calcium (Ca) 1 atom of oxygen (O)
calcium + oxygen --> calcium oxide Ca + O --> CaO
ca+o2=cao
Ca + O = CaO.
40 g / 56 g X 100%
40 g / 56 g X 100%
CaO ; 1 atom of Calcium (Ca) 1 atom of oxygen (O)
40 g / 56 g X 100%
The percent composition by element of Ca(C2H3O2)2 is calcium 25.339%, hydrogen 3.824%, carbon 30.375%, and oxygen 40.462%.
calcium + oxygen --> calcium oxide Ca + O --> CaO
Ca = calcium , O = oxygen and written together like CaO it stands for calcium oxide.
ca+o2=cao
Ca + O = CaO.
how do you write a balanced chemical formula for this question CaO + H2O ---> Ca(OH)2
Ca+O=CaO
CaO+B2O3______Ca (BO2)2
