Explanation:
Answer:
A) 
B) 7.5 molar
Explanation:
A) <u>Reduction</u>

<u>Oxidation</u>

Multiplying the oxidation reaction by 5/2 and adding it to the reduction equation:

+

-----------------------------------------------------------------------------------------------------

B) 10 ml = 0.01 L
20 ml = 0.02 L
mol of MnO4− = molarity*volume = 1.5*0.02 = 0.03
1 mol of MnO4− reacts with 5/2 mol of H2O2, then:
mol of H2O2 = 0.03*5/2 = 0.075
molarity = mol/volume = 0.075/0.01 = 7.5 molar
Rate=[a]*([b]^2)*([c]^(1/2)]
rate=[2a]*([b]^2)*([2c]^(1/2)]= 2*(2^(1/2)[a]*([b]^2)*([c]
it increases times 2*(2^(1/2)=2√2
Answer:
29.3 g HClO₄
Explanation:
We have 39.1 grams of 74.9 wt% aqueous perchloric acid solution, that is, there are 74.9 grams of perchloric acid in 100 grams of perchloric acid solution. The mass, in grams, of perchloric acid contained in 39.1 grams of perchloric acid solution is:
39.1 g Solution × (74.9 g HClO₄/100 g Solution) = 29.3 g HClO₄
Too many to know in the world.
