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.

B. The nucleus of an atom contains protons and neutrons.
Answer:
No reaction.
Explanation:
An Arrhenius base (like NaOH) increases the concentration of hydroxide ions present in the solution.
If you add Rb to an aqueous solution of NaOH, you will get an explosion.
However, the Rb does not react with the OH^-. Instead, it reacts rapidly with the water.
2Rb + 2H2O → 2RbOH + H2
So much heat is generated that the hydrogen explodes:
2H2 + O2 → 2H2O
Answer:
169
Explanation:
protons+neutrons=atomic mass
70+99=169
