Answer:
The answer to question 3 should be C. Summarizing the results.
The answer to question 4 should be D. Comparing data from the experiment to the prediction of the hypothesis.
Explanation:
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.
<span>Take the inversion of density: 1mL/13.6 g and multiply it by the conversion factor 453.6 g/ 1 lb and the given 5.00 lb. Units for mass (grams) and units for weight (lbs) cancel leaving only units of volume. I believe it should be 167 mL or 0.167 L</span>
Answer:
Heterogeneous mixture
Explanation:
Soil is composed of small pieces of a variety of materials, so it is a heterogeneous mixture.
Bromine. both Bromine and Mercury are both a liquid at STP. :)
