Answer:
30 moles of CO₂
Explanation:
balanced equation ,
CS₂+3O₂ → CO₂+2SO₂
From equation, 3 moles of O₂ are needed to make 1 mol of CO₂.
This means to produce 1 mol of CO₂, we need 3 moles of O₂, then how many moles of CO₂ will be produced from 90 moles of O₂ ?
Use unitary method to solve such problems,
Number of moles of CO₂ that will be produced:
=
=
= 30 moles of CO₂
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
The radiation source that provides the greatest radiation dose is one year of natural background radiation.
The answer is answer choice B
