Answer:
2.82 atm
Explanation:
Initial:
V1 = 28 liters, T1 = 450 C = 450 + 273 K = 723 K, P1 = ?
Final:
V2 = 34 liters, T2 = 350 C = 350 + 273 K = 623 K, P2 = 2.0 atm
Use P1 * V1 / T1 = P2 * V2 / T2
so P1 = P2 * (V2/V1) * (T1/T2) = 2.0 * (34/28) * (723/623) = 2.82 atm
The equation for the distance is:
(a/60) × 8 mi/min + (b/60) × 7.5 mi/min = D
We know that she runs 45 minutes each day, such that she runs at a rate of 8 miles per hour for a minutes, and then runs at 7.5 miles per hour for b minutes.
Now, remember the relation:
speed × time = distance.
Because a and b are in minutes, we need to rewrite the speed in minutes, remember that there are 60 minutes in one hour, then:
8 mi/h = (1/60) × 8mi/min
7.5 mi/h = (1/60) × 7.5 mi/min
Then the equation for the distance is:
a × (1/60) × 8 mi/min + b × (1/60) × 7.5 mi/min = D
(a/60) × 8 mi/min + (b/60) × 7.5 mi/min = D

The two true statements about redox reactions are:
C. One type of atom is oxidized and another is reduced.
D. Electrons are transferred from one atom to another.
<h3>What is a redox reaction?</h3>
A redox reaction is also known as an oxidation-reduction reaction and it can be defined as a type of chemical reaction in which the oxidation number of an atom of participating chemical species are changed.
This ultimately implies that, the two true statements about redox reactions include the following:
- One type of atom is oxidized while the other is reduced.
- Electrons are transferred from one atom of participating chemical species to another.
