Answer 1

The question is in complete, complete question is :

Balance each of the following chemical equations. (Use the lowest possible coefficients for all reactions.

a)$CsO_2(s)+H_2O(l)\rightarrow CsOH+O_2(g)+H_2O_2(aq)$

b)$Fe_2O_3(s)+HCl(aq)\rightarrow FeCL_3(aq)+H_2O(l)$

c)$H_2S(g)+O_2(g)\rightarrow SO_2(g)+H_2O(g)$

d)$POCl_3(l)+H_2O(l)\rightarrow H_3PO_4(aq)+HCl(g)$

e)$CaO(s)+C(g)\rightarrow CaC_2(s)+CO_2(g)$

Answer:

Explanation:

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.  

This also means that total mass on the reactant side must be equal to the total mass on the product side or total number of all atoms of each elements on reactant sides are equal to the total number of all atoms of each element on product side

a)$CsO_2(s)+H_2O(l)\rightarrow CsOH+O_2(g)+H_2O_2(aq)$

$2CsO_2(s)+2H_2O(l)\rightarrow 2CsOH+O_2(g)+H_2O_2(aq)$

b)$Fe_2O_3(s)+HCl(aq)\rightarrow FeCl_3(aq)+H_2O(l)$

$Fe_2O_3(s)+6HCl(aq)\rightarrow 2FeCl_3(aq)+3H_2O(l)$

c)$H_2S(g)+O_2(g)\rightarrow SO_2(g)+H_2O(g)$

$2H_2S(g)+3O_2(g)\rightarrow 2SO_2(g)+2H_2O(g)$

d)$POCl_3(l)+H_2O(l)\rightarrow H_3PO_4(aq)+HCl(g)$

$POCl_3(l)+3H_2O(l)\rightarrow H_3PO_4(aq)+3HCl(g)$

e)$CaO(s)+C(g)\rightarrow CaC_2(s)+CO_2(g)$

$2CaO(s)+5C(g)\rightarrow 2CaC_2(s)+CO_2(g)$
