In order to compute the mass of MgO formed, Niven must first convert grams of Mg to moles.
The chemical reaction equation provides a ratio between the moles of magnesium and magnesium oxide. Thus, in order to determine the amount of MgO formed, the amount of Mg reacted must be known.

Solving:
Moles Mg = 28 / 24 = 1.17

Moles of MgO = 1.17
Mass of MgO = 1.17 * 40.3
Mass of MgO = 47.2 grams

Answer:

Weathering and erosion

Explanation:

Weathering can be explained as the breaking down of rocks/minerals on the surface of the Earth as a result of contact with biological organism, water, air and other factors

. There are 3 common types of weathering which are;

1) physical weathering

2) biological weathering

3) chemical weathering

Erosion can be regarded as a geological process, whereby earthen material are been transported away by natural forces, these forces could be wind as well as water.

Therefore, as you were climbing a a mountain, you noticed that rocks were crumbling below your feet and moving down the mountain. What is observed are weathering and erosion processes.

After the weakening and broken up of the rock by weathering then erosion transport the bit of the rock down the mountain as you are climbing, which means the "weathering process" breakdown and the "erosion process" involves the transport or movement of the bit of the rocks
