Answer:
The drawing of the structure is found in diagram 1 of the attached figure.
Explanation:
Diagram 1 shows that three different types of protons are found in the structure. The nine hydrogen atoms have a similar behavior, the six hydrogen atoms also have a similar behavior and finally, the three hydrogen atoms adjacent to oxygen have a similar behavior. The number of peaks are as follows:
9H = singlet peak = between 3 and 4 ppm
6H = singlet peak = 4 ppm
3H = singlet peak = 3 ppm.
The 9 protons are around 3.5 ppm and the 6 hydrogen atoms show a peak at 4 ppm, and finally, the 3 protons have a peak around 3 ppm. Therefore, the corresponding drawing can be seen in diagram 2.
Answer:
Explanation:
Given parameters:
Volume of CO₂ = 24cm³
time taken for the reaction to complete = 8minutes.
Unknown:
rate of reaction
Soution
The reaction rate is a measure of speed of a chemical reaction. It is often calculated using the expression below:
Reaction rate =
Reaction rate = = 3cm³/min
In this reaction, 3cm³ of carbon dioxide were produced per minute
