Question
What are the coefficients that would properly balance this equation?
__Ca + __H2O → __Ca(OH)2 + __H2
- 2, 1, 2, 1
- 1, 2, 1, 1
- 1, 2, 2, 4
- 1, 2, 2, 1
Hint:
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products.
The correct answer is: 1, 2, 1, 1
The coefficients that would properly balance this equation are:
1Ca + 2H2O → 1Ca(OH)2 + 1H2
