Answer:
0.07973 moles of O2 gas were produced
2.66 atm
Explanation:
Using the ideal gas equation
PV =nRT
P =pressure = 2.9 atm
V= volume = 720 mL = 720mL/1000= 0.72 L
n = number of moles = ?
R = the gas constant = 0.0821 atm L/(mol K)
T = temperature in Kelvin = 319 K
make n subject of the formula
n =PV/RT
n = 2.9 atm x 0.72 L / 0.0821 atm L/(mol K) x 319K = 0.07973 moles of O2 gas were produced
Pnew = atm?
P = nRT/V
= 0.07973 x 0.0821 atm L/(mol K) x 293K/0.72 L = 2.66 atm

Answer:
A certain vehicle loses 3.5% of its value each year. If the vehicle has an initial value of $11,168, construct a model that represents the value of the vehicle after a certain number of years. Use your model to compute the value of the vehicle at the end of 6 years.

I never heard of intensity and potency before, but im just gonna assume they're another term for potential and current.
Basic concept to knowing how to solve circuit is:
1.) Current in series are the same.
2.) Voltage in parallel are the same
3.) Resistors in series can be add up with
4.) Two resistors in parallel adds up with
5.) Know how to use kirchoff current law and kirchoff voltage law. You gotta learn this by yourself because it does take some practice to get used to.
