Answer 2

Answer:

Balance the following equations:

PCl5(s)+H2O(l)→POCl3(l)+HCl(aq)PCl5(s)+H2O(l)→POCl3(l)+HCl(aq)

Cu(s)+HNO3(aq)→Cu(NO3)2(aq)+H2O(l)+NO(g)Cu(s)+HNO3(aq)→Cu(NO3)2(aq)+H2O(l)+NO(g)

H2(g)+I2(s)→HI(s)H2(g)+I2(s)→HI(s)

Fe(s)+O2(g)→Fe2O3(s)Fe(s)+O2(g)→Fe2O3(s)

Na(s)+H2O(l)→NaOH(aq)+H2(g)Na(s)+H2O(l)→NaOH(aq)+H2(g)

(NH4)2Cr2O7(s)→Cr2O3
