Answer:
Supersaturated solution.
Explanation:
Hello!
In this case, according to the types of solution in terms of the relative amounts of solute and solvent, we can define a point called solubility at which the amount of solute is no longer dissolved in the solvent; thus, a value of solute/solvent less than the solubility is related to unsaturated solutions, equal to the solubility is related to the saturated solutions and more than the solubility to supersaturated solutions.
Thus, since solubility is temperature-dependent, at 30 °C the solubility of sodium chloride is 36.09 g per 100 mL of water; which means that, since the solution has 50 g of sodium chloride, more than 36.09 g, we infer this is a supersaturated solution.

Explanation:
The valency of sodium is 1 because it loses it's one valence electron to gain its octet state (state of having 8 electrons in shell) during the chemical reaction.

The correct option is C.
When glucose is stirred into water to form a solution, then glucose is the SOLUTE and water is the SOLVENT. A solute refers to a substance that is dissolved in a solvent. For instance, salt is the solute that is dissolved in salt solution. A solvent on the other hand refers to the liquid into which the solute was dissolved. For instance, in the case of salt solution, water is the solvent, because it is used to dissolve the salt.
Answer:
1:1.

Hello!
In this case, since magnesium, in the form that is able to react with sulfur, has an oxidation state of 2+ and sulfur 2-, because they need to be different in order to form a suitable compound; due to that equality in their oxidation states, we expect they react in a 1:1 mole ratio, according to the following example:
