Question

balance the following equation:
ag₂s + cucl₂→agcl + cus
when the equation is properly balanced, the correct coefficients are, respectively

Explanation:

Step1: Balance Ag atoms

There are 2 Ag atoms in \(Ag_2S\). In \(AgCl\), to balance Ag, if we put 2 in front of \(AgCl\), we have \(Ag_2S+CuCl_2
ightarrow2AgCl + CuS\)

Step2: Check other atoms

For S: 1 atom on left (\(Ag_2S\)) and 1 atom on right (\(CuS\)). For Cu: 1 atom on left (\(CuCl_2\)) and 1 atom on right (\(CuS\)). For Cl: 2 atoms on left (\(CuCl_2\)) and 2 atoms on right (2\(AgCl\))

Answer:

1, 1, 2, 1
