Option C

Plants, cellular respiration accurately represents a carbon source and the process that releases carbon from that source

<u>Explanation:</u>

Every existing body supplies CO2 off while they evoke power from their food through cellular respiration. Plants and creatures present off CO2 while living and respiring and during lifeless and rotting. Plants are significant carbon sinks, gaining up enormous volumes of CO2 through the manner of photosynthesis.

While plants also discharge CO2 during the means of respiration, the volume of CO2 exercised up by plants by photosynthesis and discharged by exhalation approximately matches out. Volcanic action, forest wildfires, and diverse anthropological exercises deliver carbon.

The following mechanism has been proposed for the conversion of tert-butyl bromide to tert-butyl alcohol in aqueous solution: st
Gelneren [198K]

Answer:

See explanation

Explanation:

The first step in this reaction is a unimolecular reaction. It involves the formation of the carbocation. This is so because tertiary alkyl halides only undergo substitution by SN1 mechanism due to sterric crowding.

The second step in the reaction is bi molecular. In this step, the carbocation now combines with the OH^- to yield the alcohol.

Net equation of the reaction is;

(CH3)3CBr + OH^- -------> (CH3)3COH + Br^-

The intermediate here is the carbocation,  (CH3)3C^+

Explain how chemicals and chemical reactions are an important part of our lives.
Zielflug [23.3K]
Chemical reaction is the basis of life for living organisms; no organism can remain alive without the occurrence of chemical reactions.
Chemical reactions that occur in the living organisms are called biochemical reactions, these reactions are needed for the organism to grow, develop, survive and remain alive; when the chemical reactions stop the organism die.
For instance, to remain alive one has to eat. The food eaten can not be useful to the body if the digestive enzymes do not carry out chemical reactions on it and convert it to a form that can easily enter the blood where it is needed.

What causes the output work of a machine to be less than the input work?????
melisa1 [442]

Inefficiency of the material or engine causes the output work of a machine to be less than the input work. It is governed by the second law of thermodynamics wherein no product of work can produce 100 percent efficiency. Only the Carnot engine can produce a 100 percent effieciency.
