Answer:
A and B
Explanation:
This is because there was emission of gamma (Y) radiations in both the reactions.
You need to find moles of the gas, so you would use the ideal gas law:
PV=nRT
Pressure
Volume
n=moles
R= gas constant
Tenperature in Kelvin
n= PV/RT
(1.00atm)(1.35L)/(.08206)(332K) = 0.050mol
Molar mass is grams per mole, so
(3.75g/.050mol) = 75g/mol
Answer:
Solar panels and solar cells.
Explanation:
The word "solar" means "relating to or denoting energy derived from the sun's rays".
