Explanation:
a) K(s) + I2(s) --> KI(s)
The balanced equation is;
2K(s) + I2(s) --> 2KI(s)
b) Mg(s) + Br2(l) --> MgBr2(s)
The balanced equation is;
Mg(s) + Br2(l) --> MgBr2(s)
c) KBr(aq) + AgNO3(aq) --> KNO3(aq) + AgBr(s)
The balanced equation is;
KBr(aq) + AgNO3(aq) --> KNO3(aq) + AgBr(s)
d) KClO3(s) --> KCl(s) + O2(g)
The balanced equation is;
2KClO3(s) --> 2KCl(s) + 3O2(g)
e) C2H6(g) + O2(g) --> CO2(g) + H2O(l)
The balanced equation is;
2C2H6(g) + 7O2(g) --> 4CO2(g) + 6H2O(l)
f) Al(s) + O2(g) --> Al2O3(s)
The balanced equation is;
4Al(s) + 3O2(g) --> 2Al2O3(s)
g) P4(s) + H2(g) --> PH3(g)
The balanced equation is;
P4(s) + 6H2(g) --> 4PH3(g)
