Answer:
Here’s what I find.
Explanation:
A. Dermatan sulfate and keratan sulfate are examples of glycosaminoglycans (GAGs). TRUE.
They are both long unbranched polymers in which the repeating unit is a disaccharide consisting of a uronic sugar and an N-acetylated amino sugar.
D. Glycosaminoglycans are heteropolysaccharides composed of repeating disaccharide units. TRUE.
A heteropolysaccharide contains two or more monosaccharides, and GAGs contain a hexoseuronic acid and an N-acetylhexosamine.
B. FALSE. GAGs consist of only two residues, but they are the disaccharide units in a polymer chain that has a molecular weight greater
than 2.5 × 10^6 u.
C. FALSE. Dextran is a polysaccharide of glucose.
E. FALSE. The amino groups in the amino sugars are acetylated, so they are acetamide derivatives. Amides (Kb = 10^-15) are much less basic than amines (Kb = 10^-5), so they are not protonated.
The balanced chemical
reaction will be:
C3H8 + 5O2 = 3CO2 +4H2O
We are given the amount of propane gas to be burned. This will be
our starting point.
<span>0.025 g C3H8 ( 1 mol C3H8 / 44.1 g C3H8 ) ( 5 mol O2/1
mol C3H8)(32 g O2 / 1 mol O2) = 0.09 g O2</span>
