He because nitrogen and ozone is a molecule but helium is atom
frez [133]3 years ago

<u>Ans: Thus, O3 and He are not the formulas for diatomic. Only N2 is a diatomic</u>

A monatomic system consists of only a single element

A diatomic system consists of two elements

A polyatomic systems consists of more that two elements

1) N2: nitrogen molecule is composed of 2 N atoms. Hence it is a diatomic

2) O3: ozone is composed on 3 O atoms. Hence it is a triatomic (polyatomic)

3) He: Helium is  simply a monatomic

This gas can be formed if a hydrogen bomb is detonated.
Levart [38]

Answer:

Helium.

Explanation:

Hydrogen in the bomb is used in the process of detonation. A stream of tritium, an isotope of hydrogen is released and this fissionable material is very unstable thus it turns during the detonation to helium 3. This triggers a series of reactions that produce large amounts of heat to the surrounding environment causing destruction.

The equilibrium constant for the formation of ammonia from nitrogen and hydrogen is 1.6 × 102. what is the form of the equilibri
Nimfa-mama [501]

Answer: The expression for equilibrium constant is \frac{[NH_3]^2}{[H_2]^3[N_2]}

Explanation: Equilibrium constant is the expression which relates the concentration of products and reactants preset at equilibrium at constant temperature. It is represented as k_c

For a general reaction:

aA+bB\rightleftharpoons cC+dD

The equilibrium constant is written as:

k_c=\frac{[C]^c[D]^d}{[A]^a[B]^b}

Chemical reaction for the formation of ammonia is:

N_2+3H_3\rightleftharpoons 2NH_3

k_c=1.6\times 10^2

Expression for k_c is:

k_c=\frac{[NH_3]^2}{[H_2]^3[N_2]}

1.6\times 10^2=\frac{[NH_3]^2}{[H_2]^3[N_2]}
