Glucose generally exists in ring (cyclic) form. a haworth projection shows the orientations of the hydroxyl groups and hydrogen
atoms on the ring. draw the α and β forms of glucose by moving the groups (h, oh, or ch2oh) to the appropriate positions. for the hydroxy groups, make sure the bond on the ring is bonded to the oxygen, not the hydrogen.

The right answer is in the picture (alpha and beta glucose)
Glucose is the main source of energy in the body. It is a carbohydrate found in the diet, usually linked to more complex carbohydrates. It is once arrived in the intestine and degraded by enzymes during digestion that simple glucose is synthesized. The glucose is then converted into glycogen which is stored in the muscles and in the liver (reserve available for the entire body). In general and without any pathology, the blood glucose level is kept constant.
In the human body, both forms of glucose exist, with a predominance of beta-D-Glucose in the blood (66%).

Answer:
IHD = 0
Explanation:
Given that
C₆H₁₅N
Number of carbon atoms(n) = 6
Number of hydrogen atoms(x') = 15
Number of nitrogen atoms = 1
There is nitrogen atoms then x = x' -1
The index of hydrogen deficiency given as
So
IHD = 0
The index of hydrogen deficiency is zero.
Answer:
Concentration of sulfuric acid in the acid rain sample is 0.0034467 mol/L.
Explanation:
Volume of NaOH = 1.7 ml = 0.0017 L
Molarity of NaOH = 0.0811 M
Moles of NaOH = n
n = 0.0001378 mol
According to reaction, 2 mol of NaOH neutralize 1 mol of sulfuric acid.
Then 0.0001378 mol of NaOH will neutralize:
of sulfuric acid.
Concentration of sulfuric acid in the acid rain sample: x
Concentration of sulfuric acid in the acid rain sample is 0.0034467 mol/L.
