Balance the following equation:
CaCl, + H2O
Ca(OH), + HCl
Answers
Answer:To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.
Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.
Ionic charges are not yet supported and will be ignored.
Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.
Compound states [like (s) (aq) or (g)] are not required.
You can use parenthesis () or brackets [].
Explanation:
Answer:
Cacl + H^2o ---- Ca( oh) + HCl
Balancing equation
atoms in atoms in
reactant side. product side
Ca = 1. ca = 1
cl. - = 1. cl =1
H - = 2. H - 1 + 1 = 2
O - = 1. O = 2
No. of atoms in reactant sode is equal to the no. of atoms in product side
It is already balanced
