Ethanol (ch 3 ch 2 oh) is dehydrogenated in the presence of air over a catalyst, and the following reactions take place: ch3 ch2 oh → ch3 cho + h2 2ch3 ch2 oh + 3o2 → 4co2 + 6h2 2ch3 ch2 oh + 2h2 → 4ch4 + o2 separation of the product, ch3 cho (acetaldehyde), as a liquid leaves an output gas with the following orsat analysis: co2 0.7%, o2 2.1%, co2.3%, h2 7.1%, ch4 2.6%, and n2 85.2%. how many kilograms of acetaldehyde are produced per kilogram of ethanol fedinto the process?

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
