<u>Conservation is the most important strategy in the soil management programs of agriculture</u>
In the soil management various practices are followed which will help to conserve the soil and so as to increase the fertility of the soil. Being the most important step conservation is very mandatory, as the building up of new soil will take a lot of time. It also protects the soil from the bad weather and protects the erosion. In conservation process it helps in the nutrient preservation, which can give good yield when practised cultivation. More crops can be easily grown , which will fetch more money. The conserving soil can also help in biochar fertilizer.
The block shown above is a cube of halite. Each side measures 3 cm. Then the volume of the cube of halite is 27 cm³.
<u>Explanation:</u>
Step 1:
All the sides of the cubes are equal.
Step 2:
Given,
a= 3 cm
Step 3:
Volume of the cube = a³
= 3 × 3 × 3
= 27 cm³
Hence, The volume of the cube is 27 cm³
Answer:
Properties Of Carbon :
Explanation:
Carbon:
Symbol: C
Electronic Configuration: 2 , 4
Valency : 4 (Tetra-valency)
Occurrence in nature →Earth's crust → 0.02% in the form of minerals like carbonates, coal, petroleum.
In atmosphere -0.03% in carbon dioxide is ( gaseous form)
Properties of carbon:
- Carbon forms Covalent is bonding and Covalent compounds wwhich do not conduct electricity.
- Carbon has three allotropes i.e Diamond, Graphite and Fullerenes.
- In diamond carbon atoms bonded together in tetrahedral lattice arrangement.
- In graphite carbon atoms are bonded together in sheets of hexagonal lattice.
- In Fullerenes ccarbon atoms are bonded together in spherical, tubular, or ellipsoidal forms.
- Carbon plays a major role in organic compounds.
- Carbon is a Tetravalency. (valency :4)
- So that it is easily share the electrons so that it gives a possibility of large number of compounds. Carbon compounds are also called as organic compounds. Carbon compounds are also called organic compounds.
