Explanation:
Answer: The correct answer is Glucose.
The chemical formula of the given molecules are-
Carbon dioxide is CO₂, which means that it contains 2 oxygen and 1 carbon atom and therefore 3 atoms per molecule.
Glucose- C₆H₁₂O₆, which means that it contains 6 carbon, 12 hydrogen, and 6 oxygen atoms. Thus, total atoms are 24 per molecule.
Oxygen- O₂, which means that it contains 2 atoms of oxygen.
Water- H₂O, which means that it contains 2 hydrogen and 1 oxygen atom and therefore 3 atoms per molecule.
Thus, glucose has greatest number of atoms per molecule.
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>
