Answer:
1. 2Ca + N[tex]_{2}[/tex] → 2CaN
2. 4Li + O[tex]_{2}[/tex] → 2Li[tex]_{2}[/tex]O
3. 2KCl + BaF[tex]_2[/tex] → 2KF + BaCl[tex]_2[/tex]
4. CH[tex]_4[/tex] + 2O[tex]_2[/tex] → CO[tex]_2[/tex] + 2H[tex]_2[/tex]O
Be sure to balance the number of atoms on both sides of each equation only by adding coefficients to the compounds!!!! Those without a coefficient are meant to have a coefficient of 1.
