We know that we use carbon-14 for radiometric dating of any fossil or old substance containing carbon
. The choice of Carbon-14 for dating purpose is due to its radioactive nature
So after a certain time period the amount of C-14 decreases from a body after death and by measuring the amount of Carbon 14 remained in a body we can assess the age of that particular body
A living organism continuously exchange Carbon -14 from atmosphere and this stops after death.
We study gas since reformation in order to
- Alter the the properties of hydrocarbon in the process of changing it's molecular structure.
- Its study also allows us to understand the behavior of matter.
<h3>What are the properties of gases?</h3>
Below are some few gas properties:
- Diffusibility.
- Compressibility
- Expansibility
- Low Density
<h3>What is gas reformation?</h3>
Gas reformation is defined production process which builds upon the existing natural gas.

Answer:
Potential Energy
Explanation:
Not sure how to explain it but C and D could be crossed off as answers, kinetic energy would be if it was released (?)
sorry if im wrong
<span>The half-life of a first-order reaction is determined as follows:
</span>t½<span>=ln2/k
From the equation, we can calculate the </span><span>first-order rate constant:
</span>k = (ln(2)) / t½ = 0.693 / 90 = 7.7 × 10⁻³
When we know the value of k we can then calculate concentration with the equation:
A₀ = 2 g/100 mL
t = 2.5 h = 150min
A = A₀ × e^(-kt) =2 × e^(-7.7 × 10⁻³ × 150) = 0.63 g / 100ml
= 6.3 × 10⁻⁴ mg / 100ml
