Answer:
It is observed that H2 gas gives out 286kJ/m, Methane gives out 802.3kJ/m and hexane gives out 4163kJ/m of heat. They are all exergonic or exothermic reaction but have different values of heat given out. The amount of carbon atom present, is what determines the heat given out, as higher carbon compound like Hexane gave out more heat than Methane and Hydrogen gas have out the least.

Answer:
1)50.007 grams of an isotope will left after 10 years.
1)25.007 grams of an isotope will left after 20 years.
3) 23 half-lives will occur in 40 years.
Explanation:
Formula used :
where,
= initial mass of isotope
N = mass of the parent isotope left after the time, (t)
= half life of the isotope
= rate constant
We have:
1) mass of isotope left after 10 years:
t = 10 years
2) mass of isotope left after 20 years:
t = 20 years
3) Half-lives will occur in 40 years
Mass of isotope left after 40 years:
t = 40 years
number of half lives = n
n = 23
23 half-lives will occur in 40 years.
