The reaction of 15 moles carbon with 30 moles O2 will
chubhunter [2.5K]

Answer:

15 moles.

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

C+O_2\rightarrow CO_2

Clearly, since carbon and oxygen are in a 1:1 molar ratio, 15 moles of carbon will completely react with 15 moles of oxygen, therefore 15 moles of oxygen remain as leftovers. In such a way, since carbon and carbon dioxide are also in a 1:1 molar ratio, the theoretical yield of carbon dioxide is 15 moles based on the stoichiometry:

n_{CO_2}=15molC*\frac{1molCO_2}{1molC} \\\\n_{CO_2}=15molCO_2

Best regards.

Vera_Pavlovna [14]

Question

<em>which cell living organism are diploid?</em>

Answer:

<em>Ploidy is the area of biology that refers to the number of chromosomes in a cell. Therefore, cells with two sets are diploid, and those with one set are haploid. In diploid organisms, such as humans, the haploid cells are used only for the sex cells for reproduction, while the rest of the cells are diploid.</em>
