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.
The right answer for the question that is being asked and shown above is that: "b. the act<span>ual yield may be different from the theoretical yield because reactions do no always go to completion." This is the statement that is not true about "yield."

Explanation:
Answer:
C) Flush out the contaminants with an excessive amount of water.
Explanation:
Water is universal solvent. It dissolve many solutes inside it. Soil is contaminated with number of chemicals which is used by farmers for the controlling of pathogens. These chemicals remains on the soil for very long time. These chemicals are removed from the soil by applying high amount of water which flush out the chemicals from the soil.
