Answer: heck the chemistry app itll help you i dont know this answer but the app will tell u!
The order of the steps, from first to last, is as follows based on the information in the question:
1. Salt is broken down into cations and anions.
2. Anion hydration.
3. Cation hydration.
4. Cations and anions that have been dissolved start to settle as a solid salt.
5. The rate of dissolution and recrystallization are equal.
Without hydration of the ions, the cation and anion cannot get separated. The three processes of ion dissociation, cation hydration, and anion hydration must all take place at once.
<h3>Why water is an effective solvent?</h3>
Water is a great solvent that can dissolve a wide variety of compounds due to its polarity and capacity to create hydrogen bonds.

Answer:
2. 181.25 K.
3. 0.04 atm.
Explanation:
2. Determination of the temperature.
Number of mole (n) = 2.1 moles
Pressure (P) = 1.25 atm
Volume (V) = 25 L
Gas constant (R) = 0.0821 atm.L/Kmol
Temperature (T) =?
The temperature can be obtained by using the ideal gas equation as illustrated below:
PV = nRT
1.25 × 25 = 2.1 × 0.0821 × T
31.25 = 0.17241 × T
Divide both side by 0.17241
T = 31.25 / 0.17241
T = 181.25 K
Thus, the temperature is 181.25 K.
3. Determination of the pressure.
Number of mole (n) = 10 moles
Volume (V) = 5000 L
Temperature (T) = –10 °C = –10 °C + 273 = 263 K
Gas constant (R) = 0.0821 atm.L/Kmol
Pressure (P) =?
The pressure can be obtained by using the ideal gas equation as illustrated below:
PV = nRT
P × 5000 = 10 × 0.0821 × 263
P × 5000 = 215.923
Divide both side by 5000
P = 215.923 / 5000
P = 0.04 atm
Thus, the pressure is 0.04 atm

Answer:
The order of the reaction with respect to the gas = 2
Explanation:
Let the original gas pressure be [G₀]
Initial rate of reaction is given as
r = k [G₀]ⁿ
When 10% had reacted, amount of gas left = [0.9G₀], r = 9.71 Pa/s
r = k [0.9G₀]ⁿ = 9.71 (eqn 1)
when 20% had reacted, amount of gas left = [0.8G₀], r = 7.67 Pa/s
r = k [0.8G₀]ⁿ = 7.67 (eqn 2)
Dividing (eqn 1) by (eqn 2)
(9.71/7.67) = [0.9/0.8]ⁿ
1.266 = 1.125ⁿ
1.125ⁿ = 1.266
Take natural logarithms of both sides
n (In 1.125) = In 1.266
n = 0.236/0.118
n = 2.
