Moles of Li2CO3 = 1.53/73.891 = 0.0207 mole
Since HCl is in excess, amount of CO2 will depend on the limiting reagent which is Li2CO3.
∴Moles of CO2 = Moles of Li2CO3 = 0.0207.
Solving part-1 only
#1
KMnO_4
- Transition metal is Manganese (Mn)
#2
Actually it's the oxidation number of Mn
Let's find how?




- x is the oxidation number
#3
- Purple as per the color of potassium permanganate
#4

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
Na is the elemental abbreviation for sodium, and Cl is the abbreviation for chlorine.
When the two are combined, you get sodium-chloride, or table salt.
Hope that helped =)
