Answer
Explanation:
Step1: Balance first equation
$Ca + 2H_2O\rightarrow Ca(OH)_2 + H_2$
Step2: Balance second equation
$CaCO_3\rightarrow CaO + CO_2$ (already balanced, coefficients are 1, 1, 1)
Step3: Balance third equation
$2Mg+O_2\rightarrow 2MgO$
Step4: Balance fourth equation
$CuSO_4+Zn\rightarrow ZnSO_4 + Cu$ (already balanced, coefficients are 1, 1, 1, 1)
Step5: Balance fifth equation
$CaCl_2+Na_2CO_3\rightarrow CaCO_3 + 2NaCl$
Answer:
- $1Ca + 2H_2O\rightarrow 1Ca(OH)_2 + 1H_2$
- $1CaCO_3\rightarrow 1CaO + 1CO_2$
- $2Mg + 1O_2\rightarrow 2MgO$
- $1CuSO_4+1Zn\rightarrow 1ZnSO_4 + 1Cu$
- $1CaCl_2+1Na_2CO_3\rightarrow 1CaCO_3 + 2NaCl$
