User: The following chemical equation is not balanced: Fe2O3 + H2SO4 Fe2(SO4)3 + H2O When this chemical equation is correctly balanced, what is the coefficient of the water molecule? A. 1 B. 2 C. 3 D. 4

Weegy: Balanced equation is: Fe2O3 + 3 H2SO4 = Fe2(SO4)3 + 3 H2O
The coefficient of the water molecule is 3.



User: The following chemical equation is not balanced: CO2 + H2 CH4 + H2O When this chemical equation is correctly balanced, what is the coefficient of the water molecule? A. 1 B. 2 C. 3 D. 4

Weegy: The correct equation is CO2 + 4H2 = CH4 + 2H2O so the coefficient of the water molecule is 2
