There have been made 2 attempts of oxygen production by potassium permanganate. In the first attempt they have got 75ml oxygen in 3 minutes whearas there have been got 100ml in 5 minutes by the 2nd attempt. In what case the speed of the oxygen production is bigger??? Pls explain your answer

The speed of oxygen production is bigger in the first attempt.

Explanation:

In the first attempt, since 75ml oxygen is produced in 3 minutes, the rate of oxygen production is r = volume of oxygen/time = 75 ml/3 min = 25 ml//min

In the second attempt, since 100ml oxygen is produced in 5 minutes, the rate of oxygen production is r' = volume of oxygen/time = 100 ml/5 min = 20 ml//min

Since r = 25 ml/min > r' = 20 ml/min, the speed of oxygen production is bigger in the first attempt.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
