The interaction between the atoms is due to number of electrons in the valence shell
Mountains surround mono laks forming a closed hydrological basin--water fows into the lake, but it doesn't flow out. The only way for water to leave Mono Lake is through evaporation. ... Because the lake has no outlet, it is naturally saline.
Answer:
Doing an Endothermic reaction, energy is absorbed from surroundings
Explanation:
Endothermic reactions:
The type of reactions in which energy is absorbed are called endothermic reactions.
In this type of reaction energy needed to break the bond are higher than the energy released during bond formation.
For example:
C + H₂O → CO + H₂
ΔH = +131 kj/mol
it can be written as,
C + H₂O + 131 kj/mol → CO + H₂
we can see that 131 kj/mol energy is taken by the reactants. So energy is absorbed from surrounding.
Exothermic reaction:
The type of reactions in which energy is released are called exothermic reactions.
In this type of reaction energy needed to break the bonds are less than the energy released during the bond formation.
For example:
Chemical equation:
C + O₂ → CO₂
ΔH = -393 Kj/mol
it can be written as,
C + O₂ → CO₂ + 393 Kj/mol
Chemical process is responsible for the smell of vinegar in an old bottle of aspirin is Hydrolysis of ester i.e. Aspirin.
Aspirin reacts with water leading to the formation of Acetic acid which is a Carboxylic acid derivative.
Aspirin on Hydrolysis forms Acetic acid and Salicylic acid.
The reaction shows up as a fizz when aspirin is added in water.
Aspirin is called Acetyl Salicylic acid and it helps to reduce:
- Inflammation
- Pain
- Fever
- Headache
- Arthritis
- Muscle pain
- Tooth pain
Acetic acid or Ethanoic acid is a colorless liquid. It is an important carboxylic acid. It smells like vinegar.
Acetic acid is used for production of following:
- Vinyl Acetate
- Insecticides
- Rubber
- Acetic anhydride
Salicylic acid is a bitter compound which is colorless. It reduces acne and opens up the skin pores.

Answer: 429 grams of 
should be added to 1.3 L of water to prepare 2.0 M solution
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
where,
n = moles of solute = 
= volume of solution in Liters
Now put all the given values in the formula of molarity, we get
Therefore, 429 grams of should be added to 1.3 L of water to prepare 2.0 M solution
