618.936 joules. Multiplied by 4.182 though, not much difference, but
- Nitrogen as in NH₃.
- Phosphorous as in PH₃.
<h3>Explanation</h3>
Hydrogen is in group 1. It is one electron away from the next noble gas element. It would form one single covalent bond when it bonds to nonmetals.
A nonmetal atom will gain three extra electrons when it bonds to three hydrogen atoms. For the molecule to be stable, that nonmetal atom should be three electrons away from the next noble gas element. Each of the atoms in question should contain 8 - 3 = 5 valence electrons when neutral. Which column on a periodic table contains such elements?
It is B, smoke and air pollution can stress the lungs and cause things like Respiratory distress if not wearing a proper mask. That is why in places with massive amounts of air pollution many people will wear face masks.
If the enthalpy is positive and the entropy is positive, the Gibbs energy will always be positive, and the reaction will never be feasible.
<h3>What is the Gibbs Free Energy?</h3>
The Gibb Free Energy is used to obtain the feasibility of a reaction. If the Gibbs free energy is positive the reaction is not spontaneous. If the value is negative, the reaction is spontaneous while a zero values indicates equilibrium.
From the equation;
ΔG = ΔH - TΔS, it follows that if the enthalpy is positive and the entropy is positive, the Gibbs energy will always be positive, and the reaction will never be feasible.

Answer:
5511 J
Explanation:
Applying,
Q = Cm.................... Equation 1
Where Q = amount of heat required to convert ice, C = Heat of fusion of water, m = mass of ice
From the question,
Given: C = 334 J/g, m = 16.5 g
Substitute these values into equation 2
Q = 334(16.5)
Q = 5511 J
Hence, the amount of heat required is 5511 J
