Answer:
The correct answer is A) Concentration. See the explanation below, please.
Explanation:
We refer to concentration on the ratio between solute and solvent of a chemical solution. In the case of a more dilute solution, there is a higher proportion of solvent than solute and the opposite occurs in a concentrate.
Answer:
Explanation:
You calculate the energy required to break all the bonds in the reactants.
Then you subtract the energy needed to break all the bonds in the products.
2H₂ + O₂ ⟶ 2H-O-H
Bonds: 2H-H 1O=O 4H-O
D/kJ·mol⁻¹: 436 498 464
