Answer:
1. Lactose with C. β-D-galactopyranosyl (1-4) β-D-glucopyranose
2. Maltose with B. α-D-glucopyranosyl (1-4) α-D-glucopyranose
3. Sucrose with A. α-D-glucopyranosyl(1-2) β-D-fructofuranoside
4. Cellobiose with D. β-D-glucopyranosyl(1-4) β-D-glucopyranose
Explanation:
Lactose is made of β-D-glucose and β-D-galactose linked via 1→4 glycosidic linkage
Maltose is made of two α-D-glucose molecule linked via 1→4 glycosidic linkage
Sucrose is made of α-D-glucose and β-D-fructose linked via 1→2 glycosidic linkage
Cellobiose is made of two molecule of β-D-glucose linked via 1→4 glycosidic linkage
North America is in the summer season.
Answer:
Human land use impacts the environment by causing certain events which can lead to more serious events such as climate change, poor air and water quality, and environmental degradation.
One example is when humans clear out space such as forests (deforestation). This leads to habitat loss which lowers the population of certain species affecting biodiversity thus impacting the environment.
Explanation:
First, we need to find out how many moles we have of
if we are given 6.35g.
We need to calculate the molar mass of the molecule:
Cu: 63.546g
N: 14.01g * 2 = 28.02g
O: 15.999g * 6 = 95.994
Add them together to get: 187.56g
So now we need to find the number of moles we are given. This can be done by setting up a multiplication equation and cancelling the units:
So now that we know the number of moles that we have, we can use the molarity equation to find the volume of the solution. The molarity equation is:
So since we are given the molarity in the equation (0.750 M), we can plug in the molarity and moles to find the volume of the solution:
So now we know that the volume is 0.04533 Liters; however the question asks for the answer in milliliters. To do this, we must multiply by 1000:
So
the volume of the solution (<em>
in mL</em>
) is 45.33 mL.
Answer:
The product is 1-methylcyclopentanol
Explanation:
The acid-catalyzed hydration of alkenes involves the addition of a water molecule to a C=C double bond.
H₂O + C=C ⟶ H-C-C-OH
An H atom adds to one of the C atoms, and an OH group adds to the other
This reaction follows Markovnikov’s rule — the H adds to the C atom that has more hydrogen atoms, and the OH adds to the more substituted carbon.
The steps of the mechanism are:
- The aqueous sulfuric acid generates hydronium ions
- The nucleophilic π electrons attack an H atom on the hydronium ion, forming a carbocation on the more substituted C atom.
- The lone pair electrons on a water molecule attack the carbocation , forming an oxonium ion.
- Another water molecule removes the extra proton.
The product is the alcohol with the OH group on the more substituted carbon — 1-methylcyclopentanol.
