<u>Answer</u>:
"weathering breaks rocks into minerals and plants die and decay" must occur to form soil
<u>Explanation</u>:
For the formation of the soil two process are mandatory and they are erosion as well as weathering. The weathering takes place near the surface of the soil, which can occur due to various physical and chemical processes. Being an important part of soil development. It may occur rapidly or can be a slow process for decades. Water and air helps in weathering. The transport is generally by wind or with the help of flow of water, ice, etc

Answer:
Mole ratio of Carbon dioxide to Propane is;
3 : 1
Explanation:
The Balance Chemical Equation is as follow,
C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O
According to equation, 1 mole of propane reacts with five moles of Oxygen gas to produce three moles of Carbon dioxide and four moles of Water. Therefore, the mole ratio of all reactants and products can be written as,
1 : 5 : 3 : 4
Where;
1 = C₃H₈
5 = O₂
3 = CO₂
4 = H₂O
