Answer:
n=3
Explanation:
The expression for the energy of an electron for the hydrogen atom in the nth orbit is:-
Given that:-
Applying in the equation to find the value of n as:-
Hey I think it is going to be 0986 moles. Cuz we can see that no. of moles of CaCO3 which will decompose is equivalent to the no. of CaO . Now it's just the matter of finding the no. of moles of CaCO3 .

The functional group can affect the chemical properties and physical properties. Like CH3CH3 and CH3CH2OH. The first one is gas and second one is liquid. The first one is not easy to react with others while the second one is.
Earlier species thanks to evolution. hope this helped!
Answer: (a) Neon, Nitrogen; (b) Neon, Nitrogen; (c) Neon is lower than Nitrogen; (d) It doesn't affect;
Explanation: The kinetic-molecular theory studies the behavior of particles under pre-determinated situation. In cases of gases, the particles moving around colliding with each other and the walls of the container, without loss of energy. In the case in question, all the parameters are the same (same temperature, volume and pressure), except for the gases, which has different molar masses. In this sense, Neon has lower average speed due to its molar mass being higher, which means, its particles moves slower for being heavier. Related to pressure, as velocity is lower, it collides less with the walls of the tank, and so pressure is lower. For density, it doesn't affect the behavior of the system nor the kinetic energy.
