Answer:
A. The rate of the backward reaction increases.
Explanation:
The stress caused by increasing the H2O concentration would shift the system to the left, producing more reactants to counter the stress of added H2O. This means the rate of the backward reaction would increase.
Answer is: synthesis.
Chemical reaction: Ba + F₂ → BaF₂.
Synthesis is type of reaction where two or more compounds (in this reaction barium and fluorine) react to form one product (in this reaction BaF₂).
BaF₂ - barium fluoride, salt, <span>white cubic crystals, soluble in methanol and ethanol.</span>
