Answer:
The chemical reactants on the left produce<u><em> Adenosine triphosphate (ATP)</em></u> on the right.
Explanation:
Adenosine triphosphate (ATP) can be described as the energy molecule which is used by almost every cell of an organism's body to carry out normal functions of a cell.
Adenosine triphosphate (ATP) is an unstable molecule hence it usually occurs as ADP ( Adenine diphosphate) or AMP (adenine monophosphate). When a phosphate atom attaches to ADP, ATP is produced. The breakdown of ATP releases adenine diphosphate, phosphate along with the release of energy.
Answer:
2.5 mg
Explanation:
<em>The half-life of a substance is the time required for one half of the substance to decay. In order words, it is the time it will take for a substance to decay into half of its initial size.</em>
For a 20 mg element with a half-life of 30 which decays over a period of 90 years;
The first 30 years, 10 mg would have decayed, remaining 10 mg
The second 30 years, the remaining 10 mg would have decayed to 5 mg
The third 30 years, 5mg would have decayed to 2.5 mg.
Hence, in 90 years, 20 mg of the element would <u>remain only 2.5 mg.</u>
