Question

Balance the equations below (if no coefficient is needed, choose "1" from the options)

1.__K(s) +__ Cl2(g) →__KCI(s)

2. __NH3(g)→__N2(g) +__ H2(g)

3. __Ag(NO3) (aq) +__CaCl2(aq) →__AGCL(s) + __Ca(NO3)2(aq)

4. __CH4(g)+__O₂(g) → __CO2(g)+ __H₂0(g)

Answer 1

1. 2K(s) + Cl2(g) → 2KCI(s)

2. 4NH3(g) → 2N2(g) + 6H2(g)

3. 2AgNO3(aq) + CaCl2(aq) → 2AgCl(s) + Ca(NO3)2(aq)

4. CH4(g) + 2O₂(g) → CO2(g) + 2H₂0(g)
