The conservation of mass states that the total mass of reactants present before the reaction occurs is equal to the total mass of products after the reaction. From the choices, the second choice deems fit for the description of the law.
<u>Answer:</u> The volume of the container needed is 554.6 L
<u>Explanation:</u>
To calculate the volume of the gas, we use the equation given by ideal gas which follows:

where,
P = pressure of the gas = 3.0 atm
V = Volume of the gas = ? L
T = Temperature of the gas = ![25^oC=[25+273]K=298K](https://tex.z-dn.net/?f=25%5EoC%3D%5B25%2B273%5DK%3D298K)
R = Gas constant = 
n = number of moles of propane gas = 68.0 moles
Putting values in above equation, we get:

Hence, the volume of the container needed is 554.6 L
Light Spectrum:
Gamma Rays; X- Rays; Ultraviolet Rays; Infrared; Micro; Radio
I'm guessing green means the color wave
So it should be: Radio-Infrared- Green - UV - Gamma
This is because frequency decreases when going from left to right on the Light Spectrum!
Answer:
16 mol O2
Explanation:
CO + 2 O2 -> 2 CO2
1 mol CO -> 2 mol O2
8 mol CO -> x
x= (8 mol CO * 2 mol O2)/1 mol CO
x= 16 mol O2
