Answer B I believe
Not sure if it’s correct but Lina positive it is
The Balance Chemical equation is as follow,
2 Mg (s) + O₂(g) → 2 MgO(s)<span> + 72.3 kJ
According to this equation,
2 Moles of MgO formation involved = 72.3 kJ of Heat
So,
5 Moles of MgO formation will involve = X kJ of Heat
Solving for X,
X = (5 Moles </span>× 72.3 kJ) ÷ 2 Moles
X = 180.75 kJ of Heat
Hello!
The substance that is acting as the Br<span>ønsted-Lowry Acid is H</span>₂O
This is the chemical reaction:
H₂O + NH₃ → NH₄⁺ + OH⁻
In the Brønsted-Lowry Acid Concept, an Acid is a substance which donates a proton, and a Base is a substance which accepts protons. To know which compounds are acids and which are bases in this theory, we need to look at the proton movements. H₂O (The Acid) is donating a proton to NH₃ (The base), to produce NH₄⁺ (An acid) and OH⁻ (A base). Water is not commonly seen as an acid, but in this reaction, it is a Brønsted-Lowry Acid.
Have a nice day!
