Magnesium plus chlorine equals to magnesium chloride
Answer:
The answer to your question is: [H+] = 10⁻¹²
Explanation:
Remember that pH = -log [H+], then, in this exercise we need to calculate the pH of the substances and compare the results, the one which the higher value will be the strongest base.
a) [H+] = 10^-9 pH = -log[10⁻⁹] = 8
b) [H+] = 10^-11 pH = -log[10⁻¹¹] = 10
c) [H+] = 10^-10 pH = -log[10⁻¹⁰] = 9
d) [H+] = 10^-12 pH = -log[10⁻¹²] = 11 This is the strongest base
Answer:
Rate = k [OCl] [I]
Explanation:
OCI+r → or +CI
Experiment [OCI] M I(-M) Rate (M/s)2
1 3.48 x 10-3 5.05 x 10-3 1.34 x 10-3
2 3.48 x 10-3 1.01 x 10-2 2.68 x 10-3
3 6.97 x 10-3 5.05 x 10-3 2.68 x 10-3
4 6.97 x 10-3 1.01 x 10-2 5.36 x 10-3
The table above able shows how the rate of the reaction is affected by changes in concentrations of the reactants.
In experiments 1 and 3, the conc of iodine is constant, however the rate is doubled and so is the conc of OCl. This means that the reaction is in first order with OCl.
In experiments 3 and 4, the conc of OCl is constant, however the rate is doubled and so is the conc of lodine. This means that the reaction is in first order with I.
The rate law is given as;
Rate = k [OCl] [I]
