The presence of many c-c and c-h bonds causes fats to be

The right answer is the fat will become richer in energy (provides more ATPs) and more hydrophobic and less volatil.

The length of the carbon chain allows a classification of fatty acids in 4 categories: volatile fatty acids, with 2, 3 or 4 carbon atoms, short chain fatty acids which have between 6 and 10 carbon atoms, fatty acids medium chain, with 12 to 14 carbon atoms and long chain fatty acids, with 16 or more than 16 carbon atoms.

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
