Answer:
- <u>(a) 0.00587 mg/min</u>
- <u>(b) - 0.00222 mg/min</u>
Explanation:
The function that modeled the data is:
Since you need to determine how rapidly the concentrations will vary (increase or decrease) at different times, this is the instantaneous speed or rate of change, you need to find the first derivative of C(t), C'(t)
The next steps show the use of the rule of chain to find C'(t):
Now that you have the expression for the speed at which the concentration changes, you just need to substitute the values.
(a) How rapidly was the BAC increasing after 9 minutes? (mg/mL)/min
(b) How rapidly was it decreasing half an hour later (t = 30)? (mg/mL)/min
Answer: acetone is a ketone and not an aldehyde. Therefore it's false
Explanation:
Acetone is of structure CH3-CO-CH3
which makes it a ketone.
Both aldehyde and ketone have a carbonyl group but there is difference between aldehyde and ketone.
Aldehydes have a general formula R-CHO
where R is a methyl group including H atom, and CHO is the functional group.
While
Ketone have the general formula R-CO-Ri
where R and Ri are methyl groups excluding H atom, and CO is the functional group.
Hint: ketones usually end with the suffix "one" as in acetone.
5.6 atm
In a container, the sum of partial pressures equals the total pressure. If the sun is 9.8 atm and the partial pressure of oxygen is 4.2 atm, the rest of the gases must account for the other 5.6 atm.
Answer:
Weather forecasting is important to the people since it helps determine future climate expectations .
