Answer:
The entropy of a substance can be obtained by measuring the heat required to raise the temperature a given amount, using a reversible process . The standard molar entropy, So, is the entropy of 1 mole of a substance in its standard state, at 1 atm of pressure. (Below are listed tips)
- At absolute zero (0 K), the entropy of a pure, perfect crystal is zero.

Answer: 1.5% w/v
Solution: (60mL)(2%) = (80mL)(x)
X = 1.5%
C
The forward and reverse processes would still be ongoing (the system is not still as in the case of static equilibrium), however, the net effect between the two processes is zero. This is what is referred to as dynamic equilibrium.
A closed system, is one that does not exchange matter or energy between it and the environment.
Explanation:
Take an example of a simplest reversible reaction like the following;
A ⇔ B
To get the dynamic equilibrium constant for the reaction we use the following equation;
Keq = [B]eq / [A]eq
Where eq denotes equilibrium.
An example of a reversible reaction where this applies is;
NH₄Cl (s) ⇔ NH₃ (g) + HCl (g)

Maybe it’s c ??? I’m not too sure sorry
Answer:
1.48381734165x 10²⁵ molecules
Explanation:
1 grams CuNo3 is equal to 0.0011897028836018 mole.
x = 5.5 moles
x = 5.5 x 1/0.0011897028836018 = 5.5/0.0011897028836018
4623.003grams
the molar mass of cuno3 =187.56 = 6.02 x10²³
4623.003g = x
187.56x = 4623.003 x 6.02 x10²³ = 27830.47806 x10²³ = 1.48381734165x 10²⁵
