Answer:
1.12 moles
Explanation:
To find the amount of moles, you need to use the Ideal Gas Law:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = moles
-----> R = Ideal Gas constant (0.08206 atm*L/mol*K)
-----> T = temperature (K)
After converting the temperature from Celsius to Kelvin, you can plug the given values into the equation and solve for "n".
P = 1.00 atm R = 0.08206 atm*L/mol*K
V = 25.0 L T = 0. °C + 273 = 273 K
n = ? moles
PV = nRT
(1.00 atm)(25.0 L) = n(0.08206 atm*L/mol*K)(273 K)
25.0 = n(22.4)
1.12 = n
I think the correct answer would be spontaneous oxidation-reduction reaction. The type of reaction in a voltaic cell is best described as a spontaneous oxidation-reduction reaction. A voltaic cell uses the energy from the chemical reaction involved to produce electrical energy. Hope this answers the question.
Answer:
Density is defined as how tightly or loosely packed a substance is, or to the number of things or people in a certain area.
At the molecular level, temperature is related to the random<span> motions of the particles (</span>atoms<span> and molecules) in </span>matter<span>. Because there are different types of </span>motion, the particles' kinetic energy (energy of motion) can take different forms, and each form contributes to the total kinetic energy of the particles.<span>
