Answer:
V₂ = 453.125 mL
Explanation:
Given data:
Initial volume = 25.0 mL
Initial molarity = 1.45 M
Final molarity = 0.0800 M
Final volume = ?
Solution:
Formula:
M₁V₁ = M₂V₂
Now we will put the values in formula.
1.45 M × 25.0 mL = 0.0800 M × V₂
V₂ = 1.45 M × 25.0 mL / 0.0800 M
V₂ = 36.25 M.mL / 0.0800 M
V₂ = 453.125 mL
Answer : The value of is -24.9 kJ/mol
Explanation :
First we have to calculate the value of 'Q'.
The given balanced chemical reaction is,
The expression for reaction quotient will be :
In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.
Now put all the given values in this expression, we get
Now we have to calculate the value of .
The formula used for is:
............(1)
where,
= Gibbs free energy for the reaction = ?
= standard Gibbs free energy = -28.0 kJ/mol
R = gas constant =
T = temperature = 298 K
Q = reaction quotient = 3.375
Now put all the given values in the above formula 1, we get:
Therefore, the value of is -24.9 kJ/mol
Why do they act like humans
False. It is not fractional distillation.
