Answer:
The answer to your question is n = 6.24 moles
Explanation:
Data
Volume = 150 l
moles = ?
Temperature = 20°C
Pressure = 1 atm
R = 0.082 atm L / mol°K
Process
1.- Convert temperature to °K
T = 20 + 273 = 293°K
2.- Use the formula of ideal gases
Formula
PV = nRT
-Solve for n
n = PV/RT
-Substitution
n = (1)(150) / (0.082)(293)
-Simplification
n = 150 / 24.026
-Result
n = 6.24 moles
The effort force is the force applied to a machine. Work input is the work done on a machine. The work input of a machine is equal to the effort force times the distance over which the effort force is exerted.
Answer:
A. Able to be lost or gained in chemical reactions.
Explanation:
Only electrons are lost or gained.
Answer:
Animals would, instead of getting energy from the food that they eat like meat or plants, they would get their energy from the sun like plants do.
Explanation:
Because like what the paper says, Chloroplasts help with the photosynthesis, which is the process in which a plant gains its energy.
