A student adds solid kcl to water in a flask. The flask is sealed with a stopper and thoroughly shaken until no more solid kcl dissolves. Some solid kcl is still visible in the flask. The solution in the flask is

saturated

Explanation:

Saturated solution is defined as the solution in which no more solute particles can be dissolved in the solvent.

Supersaturated solution is defined as the solution in which more amount of solute particles is present than the solvent particles.

Unsaturated solution is defined as the solution in which more solute particles can be dissolved in the solvent.

As no more solid KCl dissolves and some solid KCl is still visible in the flask, the solution is termed as saturated

there is none because earth is stationary and flat.

the answer is barium and copper bromide
