Answer:
0.058M is molarity of the solution
Explanation:
Molarity is defined as the ratio between the moles of solute (In this case, MgSO₄) and the liters of solution.
In the problem:
<em>Moles MgSO₄: 0.32 moles</em>
<em>Liters solution: 5.5L</em>
<em />
Molarity is:
0.32 moles / 5.5L =
0.058M is molarity of the solution
Answer: 1.79 x 10^-5
Explanation: The equilibrium constant of a reaction can be calculated from the quotient of the concentrations of the products over the concentrations of the reactants, with each termed raised to their respective stoichometric coefficients.
For acetic acid, this equilibrium expression is:
![Kc=\frac{[H+] [CH3COO-]}{[CH3COOH]}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5BH%2B%5D%20%5BCH3COO-%5D%7D%7B%5BCH3COOH%5D%7D)
Replacing the equilibrium concentrations given by the exercise into the expression above, the equilibrium constant, Kc will be obtained and it is found to be equal to 1.79 x 10^-5.
Answer:
Climate change that is caused by humans
x 0,025
HCl+KOH--> KCl + H2O
1 1
c=1M
V=25ml=0,025l ( you need the volume to be in l)
c = n/V
n=c*V
n=1*0,025=0,025 m KOH
x=0,025m
c=1 M
V=n/c
V=0,025/1=0,025l=25ml HCl
