According to the balanced chemical equation

5 h2c2o4(aq) + 2 mno4-(aq) + 6 h+(aq) → 10 co2(g) + 2 mn2+(aq) + 8 h2o(l)

0.3500 grams of oxalic acid, h2c2o4 will react with ml of 0.100 m potassium permanganate, kmno4 solution.
a) 15.5 ml
b) 38.9 ml
c) 77.7 ml
d) 97.2 ml

A) 15.5 mL

Explanation:

Given, Mass of oxalic acid = 0.3500 g

Molar mass of oxalic acid = 90.03 g/mol

The formula for the calculation of moles is shown below:

Thus,

According to the given reaction:

5 moles of oxalic acid react with 2 moles of potassium permanganate

Thus,

1 mole of oxalic acid react with 2/5 moles of potassium permanganate

0.0038876 mole of oxalic acid react with moles of potassium permanganate

Moles of potassium permanganate = 0.001555 moles

Also, considering:

Molarity = 0.100 M

So,  

Volume = 0.01555 L

Also, 1 L = 1000 mL

So, volume = 15.5 mL

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
