Answer: Antoine Lavoisier.
He classified the elements into four groups: elastic fluids, nonmetals, metals and earths. Some of the called elementes were not really elements (light and heat). Others were compounds, e.g. hydrochloric acid.
The statement was false as it mentioned, the profit-maximizing rule leaves room for cases where it is both possible and reasonable for a firm to operate at a loss over the long run
What is profit-maximizing rule ?
According to the Profit Maximization Rule, if a corporation want to maximise its profits, it must select the level of output where Marginal Cost (MC) equals Marginal Revenue (MR) and the Marginal Cost curve is increasing. To put it another way, it must generate at a level where MC = MR.
The profit maximization rule formula is as follows:
MC = MR
The marginal cost is the cost increase caused by manufacturing one extra unit of an item.
The difference in total revenue as a result of altering the rate of sales by one unit is referred to as marginal revenue. The slope of Total Revenue is also known as Marginal Revenue.
Total Revenue - Total Costs = Profit
Profit maximisation happens when there is a considerable gap or disparity between total revenue and total cost.
so the given statement the profit-maximizing rule leaves room for cases where it is both possible and reasonable for a firm to operate at a loss over the long run. was a false statement.

Answer:
9.7 x 10⁻⁴
Explanation:
HA ⇄ H⁺ + A⁻
C(eq) 0.0174 10⁻²·³⁹ 10⁻²·³⁹
=0.0041M =0.0041M
Ka = [H⁺][A⁻]/[HA] = (0.0014)²/(0.0174) = 9.7 x 10⁻⁴
A substitution is a mutation that exchanges one base for another. This can include a change in a single chemical letter. ex. changing a to g or in your case g to a. I believe the correct answer should be B.
