"Marble is typically more than 95% calcium carbonate, perhaps even 99% calcium carbonate, and calcium carbonate is a compound. Marble has a good claim to be recognized as a compound."
The biological risk for the first person than the second as a result of radiation weighting is 10 times.
<h3>
What is radiation weighting factor?</h3>
As stated in the question, radiation weighting factor (q) is the ability to transfer energy to the body.
If radiation factor of proton = 2, and radiation factor of alpha particles = 20.
- First person is exposed to alpha radiation = 20
- Second person is exposed to protons = 2
Risk of first person with respect to second person = 20/2 = 10 times higher

Methane has 2 more hydrogens than water.
Answer:
Molarity of HCl = 0.12 M
Explanation:
Given data:
Volume of HCl = 13.0 mL
Volume of NaOH = 36.11 mL
Molarity of NaOH = 0.045 M
Molarity of HCl = ?
Solution:
Formula:
M₁V₁ = M₂V₂
M₁= Molarity of HCl
V₁ = Volume of HCl
M₂ = Molarity of NaOH
V₂ = Volume of NaOH
M₁ × 13.0 mL = 0.045 M × 36.11 mL
M₁ = 1.62 M.mL / 13.0 mL
M₁ =0.12 M
