Answer: The molar volume of any gas at standard pressure and standard temperature is 22.4 liters per mole.
Explanation:The ideal gas law is PV=nRT
P is pressure and if we consider standard pressure, then we have 1.00 atm.
V is volume and that is what we are trying to solve.
n is the number of moles, which is 1.00 moles since we are trying to determine the volume of a gas in one mole.
R is the ideal gas constant which equals
0.0821 (Liters x atmospheres)/(mole x kelvin)
T is the standard temperature which is 273 kelvin.
Rearrange the equation to solve for volume.
V = nRT/P
V = (1.00 mol)(0.0821 L atm/mol K)(273 K)/ 1.00 atm
V = 22.4 L
Answer:
a stone has Kinetic energy when it hits the ground.
Explanation:
electric and radiant energy has nothing to do with the stone hitting the ground. kinetic energy has to deal with gravity.
<h2>Answer:</h2>
The correct answer is
A) Regular operation
<h2>
Explanation:</h2>
Even those workplaces that have established LO/TO processes face challenges, including: Lack of specific procedures written for each piece of equipment identifying all energy sources and energy isolation devices. Lack of comprehensive safety training for everyone in the workplace. Incorrect tag use.
So, regular operation is the primary cause of LO/TO accidents.
