36. (a) HF has higher boiling point than HCI (b) Acetic acid dimerises in benzene due to
H-Bond
(c) C -C Bond order in benzene is 1.5
(d) sigma* 2s orbital have high energy than sigma 2pz in
CO molecule .
Correct statements is/are
(1) (b) & (d) only
(3) (b) only
(2) (a) & (d) only
(4) All are correct

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

let that person have a turn to speak : )

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
