a glycosidic bond or glycosidic linkage is a type of covalent bond that joins a carbohydrate (sugar) molecule to another group, which may or may not be another carbohydrate.
Formation of ethyl glucoside : Glucose and ethanol combine to form ethyl glucoside and water. The reaction often favors formation of the α glycosidic bond as shown due to the anomeric effect.
A glycosidic bond is formed between the hemiacetal or hemiketal group of a saccharide (or a molecule derived from a saccharide) and the hydroxyl group of some compound such as an alcohol. A substance containing a glycosidic bond is a glycoside.
Answer:
26.9%
Explanation:
To obtain the percentage by mass of solution, do the following:
Data obtained from the question include:
Mass of HCl (solute) = 36g
Mass of water (solvent) = 98g
Mass of the solution = Mass of solute + Mass of solvent
Mass of the solution = 36 + 98 = 134g
Percentage by mass of the solution = Mass of solute/mass of solution x 100
Percentage by mass of solution = 36/134 x 100 = 26.9%
Answer:
yes
Explanation:
to identify an atom you need to know either it's atomic number or it's proton number
while the neutron is used to determine it's atomic mass
Answer:
The correct answer is 0.75 atm
Explanation:
We have carbon monoxide gas (CO) at the following conditions:
T= 30ºC = 303 K
V= 20.0 L
m = 17 g
The molecular weight of CO (MM CO) is the following:
MM CO= molar mass of C + molar mass of O = 12 g/mol + 16 g/mol = 28 g/mol
We calculate the number of moles (n) as follows:
n= m/MM CO = 17 g/28 g/mol = 0.61 mol
Finally we use the ideal gases equation to calculate the pressure (P):
P x V = n x R x T
P = (n x R x T)/V
P= (0.61 mol x 0.082 L.atm/K.mol x 303 K)/20.0 L
P= 0.75 atm
