The combustion of ethane (C2H6) produces carbon dioxide and steam. 2C2H6(g)+7O2(g)⟶4CO2(g)+6H2O(g) How many moles of CO2 are pro
Gwar [14]

Answer: 11.2 moles of CO_2 are produced when 5.60 mol of ethane is burned in an excess of oxygen.

Explanation:

The combustion of ethane is represented using balanced chemical equation:

2C_2H_6(g)+7O_2(g)\rightarrow 4CO_2(g)+6H_2O(g)

As oxygen is preset in excess, ethane acts as the limiting reagent as it limits the formation of product.

According to stoichiometry :

2 moles of propane produces 4 moles of carbon dioxide

Thus 5.60 moles of propane will produce=\frac{4}{2}\times 5.60=11.2 moles of carbon dioxide

Thus 11.2 moles of CO_2 are produced when 5.60 mol of ethane is burned in an excess of oxygen.

How does anaerobic respiration occur in yeast ?
slavikrds [6]
When there isn't enough oxygen for Oxidative Phosphorylation to occur, anaerobic respiration occurs. You can't produce ATP across the inner of the mitochondrial membrane or in the Krebs cycle if you don't have Oxidative Phosphorylation. As a result, the yeast employs anaerobic respiration to keep Glycolysis running, resulting in 4 ATP molecules (Net: 2) each Glucose molecule that is converted to Pyruvate.

Allowing NADH to lose hydrogen allows it to be converted to NAD, which can then be utilized to oxidize glucose to pyruvate, which produces ATP, and so on. This is best illustrated in a diagram, in my opinion.

Which are factors scientists use to classify orders of soil?
Sergio039 [100]

Answer:

Soils are a function of the five soil-forming factors: climate, organisms, relief, parent material, and time. Each of these factors range on a continuum, so the different soils of the world number in the thousands. Soil scientists recognize 12 major orders of soils.
