Explanation: Carbon dioxide is a greenhouse gas which is involved
with increasing temperature of atmosphere
Answer:
the answer to this would be c
Explanation:
This indicator is an estimate of the amount of space on the earth that an individual uses in order to survive using existing technology. This space includes the biologically productive land and water area that produces the resources consumed by that individual such as food, water, energy, clothing, and building materials. It also includes the amount of land and water required to assimilate the wastes generated by that person. In other words, the ecological footprint measures a person's demand on the bio-capacity of the Earth.
Answer:
55.7 moles of PCl₃ and 55.7 moles of Cl₂
Explanation:
The balanced chemical equation for the reaction in which phosphorus pentachloride (PCl₅) is decomposed in phosphorus trichloride gas (PCl₃) and chloride gas (Cl₂) is the following:
PCl₅(g) → PCl₃(g) + Cl₂(g)
According to the stoichiometric coefficients, 1 mol of PCl₅ produces 1 mol of PCl₃ and 1 mol of Cl₂. So, the stoichiometric ratios reactant/product are: 1 mol PCl₃/1 mol PCl₅ and 1 mol Cl₂/1 mol PCl₅. Thus, we multiply the stoichiometric ratios by the number of moles of reactant:
1 mol PCl₃/1 mol PCl₅ x 55.7 mol PCl₅ = 55.7 mol PCl₃
1 mol Cl₂/1 mol PCl₅ x 55.7 mol PCl₅ = 55.7 mol Cl₂
Therefore, 55.7 moles of PCl₃ and 55.7 moles of Cl₂ are obtained from the decomposition of 55.7 moles of PCl₅.
