The SI unit for volume is cubic meters of M^3
Answer:
Redox reactions
Explanation:
Redox reactions consists of both oxidation and reduction
one species gets oxidised and other species become reduced, both oxidation and reduction happen simultaneously
reduction is either gain of electrons or gain of hydrogen. in reduction the oxidation number of species reduces
in this reaction the reduction half equation is
O₂ + 4e --> 2O²⁻
oxidation is either loss of electrons or gain of oxygen. in oxidation the oxidation number of species increases.
Fe --> Fe²⁺ + 2e
since both these half reactions happen overall its a redox reaction
Answer:
The tropic level of an organism is the position it occupies in a food web. A food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. The tropic level of an organism is the number of steps it is from the start of the chain.
Explanation:
Answer:
(b) amino group
e) carboxyl group
Explanation:
The functional group in an organic compound distinguishes it from other compounds. It is usually the site where chemical reactions takes place.
CH₃-HC(NH₂)-COOH
There are two functional groups in this organic compoud:
- The NH₂ group is called the amino group
- The COOH is a carboxyl group
