Correct Answer: D. hatred

Correct Answer: D. N400.00

Explanation

S.P = N600.00

(100 + 50)% = N600

150% = N600

1% = \(\frac{600}{150}\)

100% = \(\frac{600}{150} \times 100%\)

= N400

Correct Answer: B. Double decomposition

Explanation

The correct method for the preparation of an insoluble salt is B. Double decomposition (also known as a precipitation reaction).

###

• Double decomposition (Precipitation): This method involves mixing solutions of two soluble salts. The ions exchange partners, resulting in the formation of an insoluble salt (which precipitates out as a solid) and a soluble salt.

* *Example:* AgNO_{3(aq)} + NaCl_{(aq)} \rightarrow AgCl_{(s)} \downarrow + NaNO_{3(aq)} (where AgCl is the insoluble salt).

• Methods A, C, and D are typically used for the preparation of soluble salts.
