Answer:
1.Only recently have scientists been able to measure the amount of CO₂ in the atmosphere and how quickly the rate is increasing. Up until 1950 the levels of atmospheric CO2 were pretty steady at 300-‐310 ppm (that's parts per million out of all the molecules in the air).
2.Levels of carbon dioxide in the atmosphere rise and fall each year as plants, through photosynthesis and respiration, take up the gas in spring and summer, and release it in fall and winter. Now the range of that cycle is expanding as more carbon dioxide is emitted from burning fossil fuels and other human activities.

Honestly I don’t know what you listed but I’m in a world history class right now and the best way to study is just read over your content and work on what you know you’re not sure about, so let’s say you are struggling with knowledge about a certain dynasty or event go over your notes or try to learn about the subject on your own. Hope this helps you out :)

Answer:
See explanation
Explanation:
Now, let us consider the equation;
2 M2E(g) + 3 E2(g) ⇌ 2 M2E4(g) ∆H < 0
This means that the reaction is exothermic. The enthalpy change is negative (less than zero). An exothermic reaction is made to proceed in the forward reaction when the temperature is decreased. Hence increase in temperature leads to the equilibrium position shifting to the left (more M2E(g)) produced.
Also, when the pressure is decreased, the equilibrium position moves towards the left more (more M2E(g)) produced.
The Human Development Index (HDI) is a statistic composite index of life expectancy, education, and per capita income indicators, which are used to rank countries into four tiers of human development.
