The delta H of -484 kJ is the heat given off when 2 moles of H2 react with 1 mole of O2 to make 2 moles of H2O. You don't have anywhere near that much reactants, only 1/4 as much
<span>actual delta H = 0.34 moles H2 x (-484 kJ / 2 moles H2) = 823 kJ </span>
<span>delta E = delta H - PdeltaV = 823 kJ - 0.41 kJ = 822 kJ</span>
Answer:
A polysaccharide found in animals.
Explanation:
Biomolecules are the important chemical compounds present in the living organisms and responsible for all the functional activities of the body. Four important biomolecules are carbohydrates, proteins, fats and lipids.
Glycogen is a carbhydrate made of the polymer of the glucose linked through the glycosidic bonds. The glycogen acts as the energy source and present in animals mainly. Glycogen is mainly stored in the liver and the skeletal muscles of the animals.
Thus, the correct answer is option (a).
Examples of specific enzymes
Lipases – a group of enzymes that help digest fats in the gut.
Amylase – helps change starches into sugars. ...
Maltase – also found in saliva; breaks the sugar maltose into glucose. ...
Trypsin – found in the small intestine, breaks proteins down into amino acids.
