Answer:
Radiation oncologist.
Explanation:
Cancer is one of the most deadly disease and half of the world population died due to cancer every year. Cancer might occur due to the mutation in the genes that control the cell cycle.
The oncologist may be defined as the individual that has specialized in the cancer and its treatment. The different radiation might use to kill the cancerous cell and the radio elements are administered in the drugs used during the chemotherapy.
Thus, the answer is radiation oncologist.

c) water vapor is less dense
Answer:
110.25grams
Explanation:
The balanced chemical equation is as follows:
H2SO4 + 2NaOH → Na2SO4 + 2H20
Based on the balanced chemical equation of the reaction given above, 1 mole of sulphuric acid (H2SO4) is required to react with 2 moles of sodium hydroxide (NaOH).
Hence, if 1 mol of H2SO4 is needed to react with 2 moles of NaOH
Then, 2.25mol of NaOH will be required to react with;
= 2.25/2
= 1.125mol of H2SO4
Using the formula, mole = mass/molar mass, we can convert the molar value of H2SO4 to its mass value.
Molar mass of H2SO4 = 1(2) + 32 + 16(4)
= 2 + 32 + 64
= 34 + 64
= 98g/mol
Therefore, mole = mass/molar mass
1.125 = mass/98
mass = 98 × 1.125
mass = 110.25grams of H2SO4
