In photosystem I, energy from sunlight<span> energizes a pair of electrons in the reaction center (replaced by a pair of electrons from photosystem II) and these are passed to molecules of NADP+ to reduce them to NADPH. This molecule carries the electrons (and potential energy) to the carbon reactions of photosynthesis.</span>

Answer: 4KO_2+2CO_2\rightarrow 2K_2CO_3+3O_2

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical equation for reaction of potassium superoxide  with carbon dioxide to produce oxygen and potassium carbonate will be:

4KO_2+2CO_2\rightarrow 2K_2CO_3+3O_2

When mixtures of gaseous h2 and gaseous cl2 react, a product forms that has the same properties regardless of the relative amoun
lilavasa [31]
According to Dalton's Atomic Theory, the <em>Law of Definite Proportion is applied when a compound is always made up by a fixed fraction of its individual elements.</em> This is manifested by the balancing of the reaction.

The reaction for this problem is:

H₂ + Cl₂ → 2 HCl

1 mol of H₂ is needed for every 1 mole of Cl₂. Assuming these are ideal gases, the moles is equal to the volume. So, if equal volumes of the reactants are available, they will produce twice the given volumes of HCl.

Economy - If there isn't a sustainable economy, it won't be able to support many people so instead they are limited.

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
