Economy - If there isn't a sustainable economy, it won't be able to support many people so instead they are limited.
Weather- If a place is too warm or too cold it can affect the population. The weather may be seen as harsh.
Government- If people are not agreeing with the government and are against, many will leave. They won't be able to withstand it.
Overpopulation- If there is too many people, they may restrict how many babies you can have and how many people can live there. China, a co

Answer:
0.6 grams of hydrogen are needed to react with 2.75 g of nitrogen.
Explanation:
When hydrogen and nitrogen react they form ammonia.
Chemical equation:
N₂ + 3H₂ → 2NH₃
Given mass of nitrogen = 2.75 g
Number of moles of nitrogen:
Number of moles = mass/ molar mass
Number of moles = 2.75 g / 28 g/mol
Number of moles = 0.098 mol
Now we will compare the moles of nitrogen with hydrogen from balance chemical equation:
N₂ : H₂
1 : 3
0.098 : 3×0.098 = 0.3 mol
Mass of hydrogen:
Mass = number of moles × molar mass
Mass = 0.3 mol × 2 g/mol
Mass = 0.6 g
