Answer
a. $C_6H_12O_6+6O_2\Rightarrow 6CO_2+6H_2O$
b. $Fe_2S_3+6HCl\Rightarrow 2FeCl_3+3H_2S$
c. $CS_2+2NH_3\Rightarrow H_2S+NH_4SCN$
Work Step by Step
We follow the following steps to balance a chemical equation:
1. Start by balancing the most complicated molecules.
2. Adjust other smaller atoms/compounds
3. Check that both sides are equal
