The force on the wall is actually the pressure exerted by gas molecules
Higher the pressure more the force exerted on the walls of container
The pressure depends upon the number of molecules of a gas
In a mixture of gas the pressure depends upon the mole fraction of the gas
As given the mole fraction of He is more than that of H2 therefore He will exert more pressure on the wall
The ratio of impact will be
H2 / He = 2/3 / 1/3 = 2: 1
Answer:
mass number
Explanation:
Answer and Explanation: The value closest to the mass of an atom is its mass number. The mass number is the total count of the protons and neutrons in the nucleus of the...
Answer:
Explanation:
Ionic bonds result from transfer of electrons, whereas covalent bonds are formed by sharing. 2. Ionic bonds are electrostatic in nature, resulting from that attraction of positive and negative ions that result from the electron transfer process; charge separation between covalently bonded atoms is less extreme.
1) D (this is the most obvious)
2) B
3) I AM PRETTY SURE LIKE 99% SURE ITS A
