Answer:
A. It measures the [products] / [reactants].
Explanation:
- The reaction quotient aids in figuring out which direction a reaction is likely to proceed, given either the pressures or the concentrations of the reactants and the products.
- It is calculated from the concentration of the products and reactants at mixing up.
- Reaction quotient (Q) = [products] / [reactants]
So, the right choice answer:
A. It measures the [products] / [reactants].

Explanation:
When a salt is dissolved in water, the solution could be acidic, basic or neutral depending on the nature of acid and base from which the salt was formed.
When a salt is formed from a strong acid and a weak base, the salt solution is acidic.
For instance, NH4Cl is a salt formed from NH3 which is a weak base and HCl which is a strong acid. The salt hydrolyses as follows;
NH4^+(aq) + H2O(l) ------> H3O^+(aq) + NH3(aq)
Hence an acidic solution is formed.
Answer:
Ký hiệu hóa học (xem thêm ký hiệu) cho nước. Mỗi phân tử nước chứa hai nguyên tử hydro (H) liên kết với một nguyên tử oxy (O).
The chemical symbol (see also symbol) for water. Each molecule of water contains two atoms of hydrogen (H) joined to a single atom of oxygen (O).
Woter is composed of oxygen and hydrogen .O2 sticks in one direction and hydrogen in other direction this is why O2 allow to bind with other water molecule.this is called van-der -wall forces .
