Answer:
The reaction rate k is 0.0012563 (1/hour).
Explanation:
We considered the reactions occurring in the plant as first order, and represented by this equation:
where y is the BOD at time t, L is the initial value of BOD and k is the reaction rate.
If we replaced with the values
y = 2 mg O2/l (1% of the initial value)
L = 200 mg 02/l
t = 8 hr
We can calculate k
The reaction rate k is 0.0012563 1/hour.

sorry if it’s incorrect! good luck
Answer:
Answer is: A. Vinegar and soda.
Neutralization is is reaction in which an acid (in this example vinegar or acetic acid CH₃COOH) and a base (in this example soda or some other base) react quantitatively with each other.
Balanced chemical reaction of vinegar and soda:
CH₃COOH(aq) + Na⁺(aq) → CH₃COONa(aq) + H⁺(aq).
Sodium acetate (CH₃COONa) is a salt.
Answer:In the winter the polar jet moves south and becomes stronger because the North Pole gets colder but the equator stays about the same temperature. This increases the temperature contrast and moves the strengthened polar front jet farther south.
