1.1 Introduction to the particulate nature of matter and chemical change
• Atoms of different elements combine in fixed ratios to form compounds, which have different properties from their component elements.
• Mixtures contain more than one element and/or compound that are not chemically bonded together and so retain their individual properties.
• Mixtures are either homogeneous or heterogeneous.
• Deduction of chemical equations when reactants and products are specified.
• Application of the state symbols (s), (l), (g) and (aq) in equations.
• Explanation of observable changes in physical properties and temperature during changes of state.

thank you. self-studying ib chemistry before the semester

[alitvvlogs]

I really apreciate your videos homie I watched this video series an hour before the test with no prior revision and i missed classes and got a 6 this guy is an angel really a dime

[criistia.n]

my final exams are coming up in 2 weeks and I will be using this to revise, manifesting

[MegaAnderson]

Thank you! so much better than my teacher.

[florianeagboton]

Who else is taking chemistry Hl despised the fact that everything is constantly telling you that it is really hard ?

[hengweizhang]

Hey, really appreciate yours videos on chem, I find it tremendously helpful! But do you have videos on the naming? Like what they call it the IUPAC, one example can be like pent-1, 3-diene. I really have no idea how to do this stuff, please help!!

[ВалентинРодригес]

Mr Weng! Im hl and i just got into ib, im actually not that good so looking forward to this experience

[milanporteous]

HIII thanks for the informative video. i have my chem final in 4 days. i was wondering when u balance question would the cofeffiicient times the coresponding varable. for example 3HC4 (h would be 3 but would we times the 3 to the c4 as well making it 12? or would C just be 4?)

[lubnaakashif]

Could you help me out with the syllabus and past papers of IB Chemistry HL? how can i approach it?

[staceylugada]

Will this same syllabus be used for students entering the DP in 2020 (graduating 2022) I will be doing HL bio and chem!

[harshithadavanam]

hey could someone help me out so im taking chem hl this year and my semester hasnt started yet but im just tryna study to keep up so is this the first yeas syllabus and also what tb should i be taking thank you

[atharvadeshmukh]

could you make a video on the latest syllabus of the IB chemistry...

[yassmindamergi]

I love his lessons but one thing annoys me and it’s that he speaks really fast about things that are important and need time to process

[FabsterPlays]

shoulddent it be 9and a half O2 for the balencing equations

[clay]

my man what happened with all the videos? am i going to have to buy some type of course from your website? rip, i'm gonna miss learning from you.

[jiashengchen]

Will watching all these video give me enough knowledge to get a 4 for my SL Chem exam?

[삼룡이-tw]

I am just a beginner of chemistry, is it normal that I ain't familiar with this stuff?

[kevinmcallister]

I don’t think “smallest part of an element” will get me any marks if they ask what’s an atom
