Answer: Solubility
Explanation:
Solubility is the ability or property of a solute which can be a solid, liquid, or gaseous chemical substance to dissolve in a solvent (solid, liquid or gas) and form a solution. The factors that affect how soluble a substance is depends on the solvent ,temperature and pressure.
Here, Mario trying to dissolve certain substances (solutes) in water (the solvent shows he is trying to find out the solubility of the substances which can be insoluble, sparingly soluble or very soluble.
Answer:
57.1 kilo Joules of heat would be released.
Explanation:
ΔH°=-57.1kJ/mol
Molarity of HCl = 2.00 M
Molarity of NaOH = 1.00 M
According to reaction , 1 M of HCl reacts with 1 M of NaOH. Then 2.00 M of HCl will react with:
of NaOH
But according to question we only have 1.00 M NaOH .So, this means that NaOH is limiting reagent and HCl is an excessive reagent.
Heat evolved will depend upon concentration of NaOH solution :
Heat evolved when 1.00 M of NaOH reacts =

Negative sign means that heat is released during the reaction.
57.1 kilo Joules of heat would be released.
