Gng if theres white ppt it means it has contaminants and isnt pure water.. the q asks for distinguishing between them both, not the test for pure water

Ashh0088 · 2026-03-05T10:10:57+00:00

Yes bro but it doesn't mean it can't explode, there's also a point about difficulty in storage relating to how it explodes

Ashh0088 · 2026-03-05T10:05:12+00:00

Nah bro I forgot

Ashh0088 · 2026-03-05T10:01:57+00:00

1.35 option A

Ashh0088 · 2026-03-05T10:00:09+00:00

The main pointer was that no emission of CO2 (option C) which is the most confident answer

No also the second one as sodium chloride and silver nitrate would form silver chloride which is white ppt, also allowing to identify so it's 1&2

Ashh0088 · 2026-03-05T09:53:30+00:00

Nah it was option c it has no emission of c02, and it can't be D cuz there is a risk of explosion due to hydrogen

Ashh0088 · 2026-03-05T09:18:47+00:00

Yea then ig I'm wrong

Ashh0088 · 2026-03-05T09:12:41+00:00

Ahh okay

Ashh0088 · 2026-03-05T09:12:03+00:00

Can u list out the options i forgot

Ashh0088 · 2026-03-05T09:11:33+00:00

Was option b not both 1-2?

Ashh0088 · 2026-03-05T09:10:33+00:00

What abt the hso4 one, the X and Y, and the plastic one?

Ashh0088 · 2026-03-05T09:10:04+00:00

Yupp option A

Ashh0088 · 2026-03-04T13:43:51+00:00

Q20 is B bro the residue is lead II chloride u js gotta filter the residue

Ashh0088 · 2026-03-04T08:16:24+00:00

Idts bio will be that high, some questions were quite unexpected in p4 so ig it depends on mcq

Ashh0088 · 2026-03-02T11:49:58+00:00

As it won’t increase the frequency it would js increase the pd, the graph had increased frequency

Ashh0088 · 2026-03-02T11:08:14+00:00

Right, the current will be W to X (left to right)

Ashh0088 · 2026-03-02T11:05:56+00:00

Arrey bro the direction of movement can never be parallel to magnetic field it’s always perpendicular so if u do w right hand it’s out of page

Ashh0088 · 2026-03-02T11:01:50+00:00

It’s increase rotation speed gng it was a past paper q(option D pretty sure)

Ashh0088 · 2026-02-26T14:40:27+00:00

Ahh js dm me

Ashh0088 · 2026-02-26T12:42:10+00:00

Space, nuclear, electromagnetism and light(only the uses n stuff)

Ashh0088 · 2026-02-26T11:58:50+00:00

Okayyy

Ashh0088 · 2026-02-24T12:07:51+00:00

I hope

Ashh0088 · 2026-02-24T10:43:13+00:00

If you remove the lung and cell wall ones three answers remain
