Answer:
When chromium chloride, CrCl2, is dissolved in water, the temperature of the water decreases. ... The attractive forces between water molecules and chromium and chloride ions is stronger, because the reaction is endothermic means the energy released in formation is less than the energy required in breaking bond.

The explanation of the how the various concentrations of acid will affect the amount of limestone has been given below.
Effects of acid rain on limestone:-
- When an acid combines with a carbonate, it produces carbon dioxide as a gas and forms a salt that is soluble in the carbonate and acid's water.
- There are several gases in the atmosphere that can dissolve in precipitation such as rain and snow.
- Some may produce acids in rain water, such as carbonic acid, sulfuric acid, and nitric acid.
- Because the concentration is modest, the rain is not highly acidic, but it is acidic enough to react with the carbonates that make up limestone.
Thus we discussed the affects of acid rain on limestones above.

Answer:
1.17 atm
Explanation:
Calculation to determine the total pressure inside the container (in atm)
Using this formula
Total pressure = Partial pressure 1 + Partial pressure 2
Where,
Partial pressure 1=0.53 atm
Partial pressure 2=0.639 atm
Let plug in the formula
Total pressure = 0.53 atm + 0.639 atm
Total pressure = 1.17 atm
Therefore the total pressure inside the container (in atm) is 1.17 atm
The number of electrons in an atom's outermost valence shell governs its bonding behaviour. Elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table. ... Nonmetals tend to attract additional valence electrons to form either ionic or covalent bonds.
