Answer:
130
Explanation:
This is because that 3atm of N2O4 is used up for the 6atm of NO2, so 1 atm N2O4 is left. Resulting in In(1/4).
Photon is the smallest possible unit of electromagnetic energy that can be absorbed or emitted.
Answer:
670.956
Explanation:
You can use this equation to solve for heat :
Q = m * c * ΔT
Q represents the heat
m represents the mass in kilograms
c is the specific heat. For aluminum, it's 897
ΔT is the change in temperature, so, 49 - 15 which is 34
Plug in the numbers and you get this :
Q = 0.022 * 897 * 34
Q = 670.956 Joules
Answer:
Weaker
Explanation:
Since the charges on nucleus and electron are opposite in nature, an attractive force exists between them. It is true in generally, that when objects are made to move closer together in the direction of an attractive force, potential energy decreases (and increases whenever attracting objects are force to move apart).
