Balancing Worksheet Practice

BALANCING EQUATIONS WS

Balance the following by adding coefficients.

 

1.   _____N2(g) +  _____H2(g) →  _____NH3(l)

2.   _____KClO3(s)  →  _____KCl(s)   +  _____O2(g)

3.   ____NaCl(s)  +  ____F2(g)  →  ____NaF(s)  +  ____Cl2(g)

4.   _____H2(g)  +  _____O2(g)  →  _____H2O(l)

5.  __AgNO3(aq) + __MgCl2(aq) → __AgCl(s)+ __Mg(NO3)2(aq)

6.  __AlBr3(aq) + __K2SO4(aq) → __KBr(aq) + __Al2(SO4)3(aq)

7.  ____CH4(g) + ____O2(g) → _____CO2(g) + _____H2O(l)
