Answer:
whats the question??? I am familiar with brainpop but if u tell me the question ill give u the asnwer
Explanation:
Answer:
D) cooling of the reaction mixture
Explanation:
Increase in temperature speedens the rate of a chemical reaction
Answer:
5 g
Explanation:
From the question, we have,
Molarity of FeIII solution= 0.245 M
Volume of solution = 125 ml
From
number of moles= concentration × volume
We have;
Number of moles= 0.245 M × 125/1000
Number of moles = 0.031 moles
Molar mass of Fe III = 162.5g/moles
Mass of iron III = number of moles× molar mass = 0.031 × 162.5= 5 g
n
Answer:
Option (E) is correct
Explanation:
Solubility equilibrium of is given as follows-
Hence, if solubility of is S (M) then-
and
Where species under third bracket represent equilibrium concentrations
So, solubility product of ,
Here,
So,
So,
Hence option (E) is correct
