Answer:
D. All of them would have the same kinetic energy
Explanation:
The expression for the kinetic energy of the gas is:-
k is Boltzmann's constant =
T is the temperature
<u>Since, kinetic energy depends only on the temperature. Thus, at same temperature, at 300 K, all the gases which are will posses same value of kinetic energy.</u>
Answer:
See the answer/explanation in the attachment
Frequency = speed of light / wavelength
= 3*10^8 / 6.50 * 10^-7
=4.61 * 10^14 sec^-1
Answer:
So, in general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant.
Explanation:
Moving from left to right across a period, the atomic radius decreases. The nucleus of the atom gains protons moving from left to right, increasing the positive charge of the nucleus and increasing the attractive force of the nucleus upon the electrons.

1 mole CH₃OH ----------- 32.0 g
2.0 mole <span> CH₃OH -------- mass g
mass = 32.0 * 2.0
mass = 64.0 g
hope this helps!
