In first pic,
1) Only the mass number decreases that means alpha particles.

So, because each alpha particle has a mass 4 amu.

We can say, that 238-206 = 4n
4n = 32
n = 8 So there will be 8 alpha particles

Now, you see there's a drop off 10 in the atomic number
And we know that atomic number of helium atom is 2
So, we can say that

10 = 2(8) + -1(m)
because, -1 is the positron atomic number

So,
-6 = -m
and, m= 6 that is 6 Beta particles

Sorry, I don't know the second one

3) Indicators are usually weak organic acids and bases like phenolphthalein, etc

4) (A) is the correct answer.
Because, Nitrogen has a lone pair , and thus behaving as an Lewis base because it can donate pair of electron it is correct as well as the reason is correct.

5) Sorry I don't know this one

Getting onto the next one

1) Bond order of Oxygen molecule is 2
2) On moving down the group, the radius of the ion increases.
3)I'm not pretty sure about these reactions though I can guess but I suppose I should not.

4) 5) 6) I don't know really sorry
7) In adiabatic process, Total heat change ∆Q = 0
8)Tyndall effect - Scattering of particles
9) Don't know
10) According to the Arrhenius equation
k = A * e^-m/RT
So,
log k = log A - m/RT * log e
Comparing this with y = mx+c
this is satisfying as a straight line having a negative slope and a positive y -intercept
So, option (C) graph given is true

11) D)Glycol is obtained on the hydrolysis

12) 13) Don't know

14) Functional isomerism is shown as in one there's carboxylic acid and in other there's ester
15) and further I don't know

I'm very sorry, I couldn't tell you , many answers but I tried helping out on what i know till now as of class 11th

Hope that much helps you a bit !
Regards
