Answer:
If carbonyl oxygen of 4-hydroxypentanal is enriched with
, then the oxygen label appears in the water .
Explanation:
- In the first step, -OH group at C-4 gives intramolecular nucleophilic addition reaction at carbonyl center to produce a cyclic hemiacetal.
- Then, one equivalent of methanol gives nucleophilic substitiution reaction by substituting -OH group in cyclic hemiacetal to produce cyclic acetal.
- If carbonyl oxygen of 4-hydroxypentanal is enriched with
, then the oxygen label appears in the water produced at the end of reaction. - Full reaction mechanism has been shown below.
Answer:
The correct answer is a The calvin cycle requires products only produced when the photsystems are illuminated .It is often too cold at night for the reaction to take place.
Explanation:
It is true that the reactions of calvin cycle are not directly depends on light but depends on the products such as ATP and NADPH produced during light reaction.
ATP and NADPH is formed by the illumination of photosystems by sun light.So during night time there is no chance for the light dependent illumination of the photosystems.
As a result the ATP and NADPH are not formed during night .That"s why reactions of calvin cycle does not occur at night.

Answer:
4.33 L
Explanation:
Assuming ideal behaviour and that all 0.300 moles of gas reacted, we can solve this problem using Avogadro's law, which states that at constant temperature and pressure:
Where in this case:
We <u>input the given data</u>:
- 2.16 L * 0.601 mol = V₂ * 0.300 mol
And <u>solve for V₂</u>:
Answer:
1. ionic bonds
2. metallic bonds
3. share
4. metal
5. non-metal
6. metals
7. NaCl ( sodium chloride )
8. CO2 ( carbon dioxide )
9. Cu ( copper )
