Answer:
Clayey soil is rich in humus and very fertile, so it is suitable for growing cereals like wheat and gram. Such soil is good at retaining water.Clayey is known to be useful for crops. Because the particle size in this soil is very fine, it has the ability to retain more amounts of water. - This makes it easy for crops to access water as it is very essential for the growth of the plant. - Some of the crops need a high amount of water in order to grow.Clayey soil is made up of fine particles that are tightly packed and increases soil density and strength. It is rich in nutrient content in the form of organic matter or humus so, it is very fertile soil. It has excellent water retaining a capacity.

Answer:
The correct answer is B. Dull appearance
Explanation:
Answer:
option A = C₂H₄ + 3O₂ → 2CO₂ + 2H₂O
Explanation:
Law of conservation of mass:
This law stated that mass can not be created or destroyed in chemical reaction. It just changed from one to another form.
For example:
C₂H₄ + 3O₂ → 2CO₂ + 2H₂O
28 g + 96 g = 88 g + 36 g
124 g = 124 g
This reaction correctly hold the law of conservation of mass.
Other options:
C + 4H₂ → CH₄
12 g + 8g = 16 g
20 g = 16 g
This reaction do not hold the law of conservation of mass.
3H₂O → 3H₂ + 3O₂
54 g = 6 g + 96 g
54 g = 102 g
This reaction do not hold the law of conservation of mass.
2Na + Cl → NaCl
46 g + 35.5 g = 58.5 g
81.5 g = 58.5 g
This reaction do not hold the law of conservation of mass.
