Ammonium chloride is acidic; hence, it reacts with a base. The answer is B as the explanation outlined.

Sir number 46 cant be C because to get ethanol the double bond has to break first then it becomes saturated 😢

I am not sure what you are stating. However, let's revisit the definition of saturation of hydrocarbon compounds. It states that the carbon atom has the maximum number of hydrogen atoms around it. In other words, 1)only carbon and hydrogen are in the compound, and 2) only single bonds( C-C) are in the compound. So, if the compound has a double bond, it is not saturated (it is unsaturated). If there are other atoms than hydrogen, it will not be a hydrocarbon compound. I hope this helps.

Regarding number 6, at timestamp 11:25, you were wondering what the examiners wanted here ~ The way I looked at it is: can we find reaction equations where a gas is acting as an oxidizing agent, and other equations where the same gas is a reducing agent ~ Turns out for hydrogen gas you can find plenty of equations where it's a reducing agent ~ But there's also a few where it's an oxidizing agent: H2 + 2Li -> 2LiH [H2 is oxidizing agent, Li is reducing agent] H2 + Y2 → 2HY [H2 is oxidizing agent, Y2 is a reducing agent] 3H2 + 2Ga -> Ga2H6 [H2 is oxidizing agent, Ga, gallium, is reducing agent] It looks like reactions with metals, hydrogen gas acts as an oxidizng agent ~ And with non-metals, it acts as a reducing agent ~ I think this fact is what they were testing Btw: Great work on all your vids! ~ Altogether [including other past papers] we have just a handful of different answers~

I dont think so because the number of electrons ARE 8. And in B, they changed the protons to 9. They asked for isotopes of X which is 8. The answer is A.
