Answer:
it would be like 30
Explanation:
just divide the gram by cubic
Answer: A) ionic salt
Explanation: Chlorine has a high electronegativity of 3.0. Copper like most metals has a low electronegativity, So the bonding is ionic making the compound an ionic salt.
Answer: four hundred and 18
Explanation:
Simple math showed that only 16 words are possible from a two-letter combination, but a three-letter code produces 64 words. Operating on the principle that the simplest solution is often correct, researchers assumed a three-letter code called a codon.
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.
