Answer:
Explanation:
The given equation is not correctly balanced. However the number of each type of atoms on right side are,
Mg = one magnesium atom
S = two sulfur atom
Cu = two cuppor atoms
Cl = two chlorine atoms
Chemical equation.
MgS + CuCl₂ → CuS + MgCl₂
Balance chemical equation:
2MgS(aq) + 2CuCl₂(aq) → 2CuS(s) + 2MgCl₂(aq)
In case of balance chemical equation number of each type of atoms on right side are,
Mg = two magnesium atom
S = two sulfur atom
Cu = two cuppor atoms
Cl = four chlorine atoms (because two chlorine atom form one chlorine molecule)
