Why do disaccharides produce more co2 than monosaccharides? ?

Explanation:  Disaccharides are the sugar which are formed by the combination of two Monosaccharides .

Monosaccharides are the class of sugar which cannot be hydrolyzed further.

Thus when Disaccharides undergo the process of combustion, more of the carbon dioxide will generate and it will be generated twice as much in comparison to that of monosaccharides.

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
