Answer:
the answer is that Mass and kinetic energy have a positive relationship, which means that as mass increases, kinetic energy increases, if all other factors are held constant.

Sike i dont know. Sorry man, but i dont know what that means - are you on crack? do you need therapy because I am a great therapist. Hmu if you'd like.
Answer:
Based on the difference in solubility one can perform the process of purification of the benzoic acid contaminated with sodium chloride. The benzoic acid does not get soluble in cold water, while the sodium chloride is soluble in cold water.
Thus, for separation, the supplementation of cold water can be done into the mixture in the experiment of purifying benzoic acid from sodium chloride. In the process, the mixture is placed on the ice bath and is stirred well, in the end, the solution is filtered. The filtrate contains sodium chloride and on the filter paper pure benzoic acid is collected.
BaSO₄(s) ⇄ Ba²⁺(aq) + SO₄²⁻(aq)
Ksp=[Ba²⁺][SO₄²⁻]
[Ba²⁺]=[SO₄²⁻]
Ksp=[Ba²⁺]²
Ksp=(1.76*10⁻³)² =3.0976×10⁻⁶ ≈3.1×10⁻⁶
Answer:
The work done is 123.5 J
Explanation:
Given that:-
Temperature = 260 K
The expression for the work done is:
Where,
n is the number of moles = 52.0 mmol =
W is the amount of work done by the gas
R is Gas constant having value = 8.314 J / K mol
T is the temperature
V₁ is the initial volume = 300 cm³
V₂ is the final volume = 100 cm³
Applying in the equation as:
The work done is 123.5 J
