Answer: 1.6L
Explanation:
V1 = 1.50 L,
V2 =?
n1 = 3mol
n2 = 3 + 0.2 = 3.2mol
From PV = nRT
V1 /n1 = V2/n2
1.5/3 = V2 /3.2
V2 = (1.5/3/) x 3.2 = 1.6L
It follows that the reaction is spontaneous at high temperatures Option A.
<h3>What is ΔS ?</h3>
The term ΔS is referred to as the change in the entropy of the system. Now recall that entropy is defined as the degree of disorderliness in a system. If a system is highly disorderly then it means that it has a high entropy. Also, ΔH has to do with the heat change that accompanies a reaction.
We know that both the entropy and the heat change can both either be positive or negative. Now we know that the equation ΔG = ΔH - TΔS can be used to ascertain whether or not a reaction will be spontaneous. If the result is negative, then the reaction will be spontaneous.
As such, when then it follows that the reaction is spontaneous at high temperatures Option A.

10. A
I hope this really helps you out
Answer:
b. Mg & Cl
a. transferred
46
Explanation:
Ionic bonds form between metals and non-metals when electrons are transferred from one specie to another.
- The electrostatic attraction from the resulting ions forms the ionic bonds.
- A metal is electropositive and will readily donate electrons
- A non-metal is electronegative and will accept electrons.
- This creates two oppositely charge ions that attracts by means of ionic bonding.
Since Mg and Cl are the only metal - non-metal pair, and ionic bond will form between them.
2.
In the specie;
₄₇Ag¹⁺
47 is the atomic number of the element Ag.
The atomic number is the number of protons in an atom. For a specie in neutral state, the number of protons and electrons are the same.
- When an atom loses electron, it becomes positively charged.
- Here Ag has lost one electron and then, the number of electrons becomes 46.
- The number of protons is still 47
