Answer: Maintaining equilibrium on Earth.

Explanation:

The biogeochemical cycles and geochemical cycles maintains equilibrium on earth by supplying the desired material required for many processes on earth.

The elements such as carbon, nitrogen and phosphorous recycle on earth and provides these nutrients to the plants and animals.

These nutrients are recycled again and again to maintain balance on earth.

A sample of the mineral hematite Iron (III) oxide has a mass of 12.4g. How many moles of the mineral are present?

8090 [49]

Thus problem is providing us with the mass of iron (III) oxide as 12.4 g so the moles are required and found to be 0.0776 mol after the calculations:

<h3>Mole-mass relationships:</h3>

In chemistry, we use mole-mass relationships in order to calculate grams from moles and vice versa. In this case, since we are given the mass of iron (III) oxide as 12.4 g one can calculate the moles by firstly quantifying its molar mass:
