I wish we didn't have to remember these :(((

THANK U VERY MUCH TEACHER I APPRECIATE THE EFFORT THANKS GOD BLESS US ALL PLEASE CONTINUE TO UPLOAD MORE VIDOES ESPECIALLY THIS PERIOD WHEN WE ARE PREPARING FOR OUR MINI EXAMS THANKS

I had a question. At 13:27 the cation gave a green ppt. Which can be both due to chromium ions or Iron(II) ions. But since Compound Z had no flame colour, that would mean it's not iron (II) so shouldn't our answer be chromium?

When will this channel grow

[@SciencewithHazel]

Soooooon (I hope...)

[@Xendruis]

@@SciencewithHazel ur contents are amazing like seriously, if I had more time to actually watch all of your videos and take lots of notes I think I would have passed my chemistry and got a higher grade in biology as levels. 😔

@@SciencewithHazel Hi, in case you weren't tagged in the previous comment I'll ask it again. I had a question. At 13:27 the cation gave a green ppt.

How can I join the classes

[@SciencewithHazel]

I’m afraid these classes only ran during lockdown in 2020.

[@vaibhav2831]

@@SciencewithHazel it's lockdown in my country are you planning any classes for this year I am in garde 12 and am struggling a lot with chemistry mainly physical

Calcium flame test is not brick red it is red orange

[@SciencewithHazel]

It's quite literally the same thing

15:06 the way you explained this part here is pathetic The explanation should be: The gas given off is basic and basic substances turn red litmus blue. We'll get 0 for that explanation that u did
