PROBLEM 35P

Write a balanced chemical equation for each chemical reaction.

(a) Solid lead(II) sulfide reacts with aqueous hydrochloric acid to form solid lead(II) chloride and dihydrogen sulfide gas.

(b) Gaseous carbon monoxide reacts with hydrogen gas to form gaseous methane (CH4) and liquid water.

(c) Solid iron(III) oxide reacts with hydrogen gas to form solid iron and liquid water.

(d) Gaseous ammonia (NH3) reacts with gaseous oxygen to form gaseous nitrogen monoxide and gaseous water.

Step-by-Step Solution:

Solution 35P

Step 1:

(a)Solid lead(II) sulfide reacts with aqueous hydrochloric acid to form solid lead(II) chloride and dihydrogen sulfide gas.

Pb(s) + HCl (g) PbCl2 (s) + H2S

Now in  both the sides the number of lead atoms are balanced . In order to balance the number of Cl and H atoms we will have to multiply 2 with HCl .

Hence the balance chemical equation will be

Pb(s) + 2HCl (g) PbCl2 (s) + H2S(s)

Step 2:

(b)Gaseous carbon monoxide reacts with hydrogen gas to form gaseous methane (CH4) and liquid water.

CO(g) + H2 CH4 (g) + H2O

The number of H atoms in reactant is 2 where as in product the total number of H-atoms are 6. In order to balance the number of H atoms multiply 3 with H2.

Now the balanced chemical equation will be,

CO(g) + 3H2 (g)CH4 (g) + H2O(l)
