Acid A, assuming the two acids have the same pH. The M stands for molarity which is how concentrated a substance is (basically the higher the molarity the more concentrated the acid is). However, pH refers to how acidic a substance is. If the two acids have different levels of acidity, the answer may be different.
2SO₂+O₂⇒2SO₃ ΔH=-197 kJ
<h3>Further explanation</h3>
Based on the principle of Hess's Law, the change in enthalpy of a reaction will be the same even though it is through several stages or ways
Reaction
2SO₂+O₂⇒2SO₃
Given :
1. S(s)+O₂(g)→SO₂(g) ΔH = -297 kJ
Reverse
SO₂(g) ⇒S(s)+O₂(g ΔH = +297 kJ
(sign change to +) x 2
2SO₂(g) ⇒2S(s)+2O₂(g ΔH = +594 kJ
2.2S(s)+3O2(g)→2SO3(g) ΔH=-791kJ
Add both reactions and remove/subtract the same compound for different sides
1. 2SO₂(g) ⇒2S(s)+2O₂(g) ΔH = +594 kJ
2.2S(s)+3O₂(g)→2SO₃(g) ΔH=-791kJ

2SO₂+O₂⇒2SO₃ ΔH=-197 kJ
Answer:
In 1 mol of anything, you have 6.02×10²³ particles, so 1 mol of F₂ contains 6.02×10²³ molecules.
Although it has a negative charge, it will never accept a

(sulfuric acid) . That is because sulfuric acid is a strong acid and completely disassociates in water.
Therefore, the sulfate ion (

Answer:
Temperature
Explanation:
It's called temperature.
This is because, in any substance an increase in temperature means that the particles on the average will move with greater speeds, or that they have greater kinetic energy while a decrease in temperature means that the particles on the average will move with lesser speeds, or that they have lesser kinetic energy.
