Answer:
The fourth option is correct K2 = (1/K1)2
Explanation:
Step 1: Data given
(1) NO(g) + ½O2(g) ⇆ NO2(g)
(2) 2NO2(g) ⇆ 2NO(g) + O2(g)
Step 2: Calculate K1
K1 = [NO2] / [NO][O2]^0.5
Step 3: Calculate K2
K2 = [NO]²[O2]/[NO2]²
Step 4: When we square the first equation
K1² = [NO2]² / [NO]²[O2]
Step 5: Calculate the reverse reaction
1/K1² = [NO]²[O2] / [NO2]² = K2
So K2 = 1/K1² = 1²/K1²
The fourth option is correct K2 = (1/K1)2

<u>Answer:</u> The chemical formula for aluminium nitrite is 
<u>Explanation:</u>
The given compound is formed by the combination of aluminium and nitrite ions. This is an ionic compound.
Aluminium is the 13th element of periodic table having electronic configuration of ![[Ne]3s^23p^1](https://tex.z-dn.net/?f=%5BNe%5D3s%5E23p%5E1)
.
To form 
ion, this element will loose 3 electrons.
Nitrite ion is a polyatomic ion having chemical formula of 
By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
So, the chemical formula for aluminium nitrite is
Answer:
Water, Ethonal, Ammonia, Sulfur Dioxide, and hydrogen sulfide.
