Answer 1

A precipitation reaction refers to the formation of an insoluble salt when two solutions containing soluble salts are combined. The insoluble salt that falls out of solution is known as the precipitate, hence the reaction's name. Precipitation reactions can help determine the presence of various ions in solution.

Answer 2

Answer and Explanation:

QUESTION:-

The mass of earth is 6 × 10²²kg and that of the moon is 7.4 × 10²²kg. If the distance between the earth and the moon is 3.84 × 10⁵km, calculate the force exerted by the earth on the moon. G = 6.7 × 10⁻¹¹ N m²kg⁻².
