Question

Choose the correct coefficients to balance the following equation: __CaCO3 + __HC; Produces __CaCl2 + __CO2 + __H2O

Answer 1

Answer:

CaCO3 + 2HCl = CaCl2 + CO2 + H2O

Explanation:

CaCO3 + HCl = CaCl2 + CO2 + H2O

Error in equation should be HCl on left hand side not HC

Left Side

Ca = 1

C = 1

O = 3

H = 1

Cl = 1

Right Side

Ca = 1

C = 1

O = 3

H = 2

Cl = 2

So we'll try and balance the Chlorine

CaCO3 + 2HCl = CaCl2 + CO2 + H2O

Left Side

Ca = 1

C = 1

O = 3

H = 2

Cl = 2

Right Side

Ca = 1

C = 1

O = 3

H = 2

Cl = 2

Yay it worked
