Answer:
The solution becomes more concentrated
Explanation:
As the solvent evaporates, the solute remains intact. This implies that we have more of the solute than the solvent in the solution. So as the evaporation continues, the resulting solution becomes more concentrated as we now have more of the solute than the solvent.
In an endothermic reaction, “delta H” is always positive, since the system is absorbing heat from its surroundings, not releasing into the surroundings like in an exothermic reaction where the delta H is always negative.
So our endothermic reactions would be the first (484kJ) and the last (92kJ).
A observation! Hope this helps you!
1.) Calculate the change in pH when 4.00 ml of 0.100 M HCl(aq) is added to 0.100 mL of a buffer solution that is 0.100 M in NH3 (aq) and 0.1000 M in NH4Cl(aq).
2.) Calculate the change in pH when 4.00 mL of 0.100 M in NaOH(aq) is added to the original buffer solution.
Answer:
yes
Explanation:
new compounds made, a chemical reaction is when a new compound is made.
