X is the oxide of a Period 3 element. X reacts with water to give an acidic solution. A solution is prepared by reacting 0.100g of X with excess water. This solution was neutralised by exactly 25.0 cm of 0.100 mol dm sodium hydroxide solution.
what could be the identity of X?
Al2O3
MgO
P4O10
SO3

Hi guys, so about half a year ago, when I was writing up my thesis, I was inspired to start my own Chemistry tutorial channel. It has since humbly continued to attract more viewers (students/learners, I assume) globally.
www.youtube.com/c/ptetchemistry
I have recently resumed teaching, albeit at a different level, and I have continued to update my channel (in my own free time) with more teaching and learning resources including lectorials (lecture tutorials), practical videos, alternative to practical (for those who did not get the chance to actually work in the laboratory) and importantly, my think-aloud tutorials for exam questions.
It is not a fancy channel, but an educational one at best. In my previous work, I was (and still am!) an accomplished synthetic organometallic chemist, working with some of the most air-sensitive compounds. My passion is however in advancing chemical education and affording equal opportunities for all who want to learn from me.
The topical playlists for O/IGCSE/GCSE (pure chemistry and combined science chemistry) make it suitable for any 14-16 years old at various stages of the curriculum, while that for A/IB make it suitable for any 16-18 years old too.
If you feel the work is worthy, do subscribe and share with friends, chat groups, relatives, etc who can benefit from these resources. To those new to YouTube (just in case), subscribing to my channel cost nothing but will support the channel/work.
You can also follow me on ptet.chemistry on IG, FB and Twitter, to get all the latest updates and to stay connected.
Cheers.
