To arrange the sublevels in order of increasing energy, we add the principal shell and the maximum number of electrons of the specific sublevel. s has 2 electrons, p has 6 electrons, d has 10 electrons, and f and 14 electrons. in this case, a) 3 + 10 = 13b) 2 + 2 = 4c) 4 + 2 = 6d) 3 + 6 = 9 
The order hence is 2s, 4s, 3p, and 3d

irinina [24]

Answer:

a)

C(s)+O_{2}(g) \rightarrow CO_{2}(g)

S(s)+O_{2}(g) \rightarrow SO_{2}(g)

b)

Sulphurdioxide

c)

SO_{2}(g) + H_{2}O(l) \rightarrow H_{2}SO_{3}(l)

SO_{2}(g) + \frac{1}{2}O_{2} \rightarrow SO_{3}(g)

d)  

Incomplete combustion produce harmful gases.

Explanation:

a)

Carbon reacts with atmospheric oxygen to form carbondioxide as well as sulphur dioxide.

The chemical equations are as follows.

C(s)+O_{2}(g) \rightarrow CO_{2}(g)

S(s)+O_{2}(g) \rightarrow SO_{2}(g)

b)

Sulfur dioxide is very harmful to the environment to cause acid rains.

This harmful gas mix with rain water to form  sulphuric acid.

c)

The balanced chemical equation for the reaction that produces harmful environmental effects is as follows.

SO_{2}(g) + H_{2}O(l) \rightarrow H_{2}SO_{3}(l)

SO_{2}(g) + \frac{1}{2}O_{2} \rightarrow SO_{3}(g)

SO_{3}(g) +H_{2}O(l) \rightarrow H_{2}SO_{4}(l)

d)

In the absence of proper amount of oxygen required for combustion, incomplete combustion will take place which will result in formation of more carbondioxide an other harmful gases.
