A. Natural Gas is a substance that is a source of hydrocarbons.
The half life of a radioactive element is the time needed to the element to decay and reach the half amount of the initial amount. Here we have a radioisotope element which decays its half from 10,000 to 5,000 in two days. Therefore, its half life is 2 days.
It would be: c/∧ = 3*10^8 / 4.25*10^-11 = 7.05 * 10^18 /s...
Answer:
-2
Explanation:
carbonate oxifation number is -2
It would be 0.341 because if you add 0.229 and 0.112 it will be 0.341
