For the first task, lighting a campfire can be used. Quantities of firestarter and kindling do not need to be precise. For the second task, the process of titration can be used. In a titration, the precise amount of a substance may be determined by adding a precise amount of a reactive species
Answer in the Word document below.
Diazonium compounds are a group of organic compounds sharing a common functional group R−N₂⁺. The process of forming diazonium compounds is called diazotation and usually <span>are prepared by treatment of aromatic amines with </span>nitrous acid<span> and additional acid (hydrochloric acid).

Answer : The mole fraction of nitrogen will be 0.4615.
Explanation : When nitrogen (
)and hydrogen (
)are mixed, the mole ratio becomes 1 : 1.5,
Now we know that (
) is acting as a limiting agent.
So at the time of when 0.4 moles of (
) is been formed it requires 0.4 moles of (
) and 3.4 moles of (
)
So, we find the the remaining (
) will be 0.6 and
(
) will be 0.3 mole present in mixture.
So, the mole fraction of (
) becomes = 0.6 / (0.6 + 0.4 + 0.3) Which becomes = 0.4615
B is correct. As you move down group 1, the elements become more reactive with other elements because the electrons have a weaker attraction to their own atoms nucleus which means attraction with other elements is much stronger, making the atom more reactive.
