43:02 Hi there, isn't it supposed to be 12.04 x 10^23 atoms?

@DrdeBruinsClassroom

Жыл бұрын

No, because that's not how standard form works. In standard form, the first number has to be between 1 and 10. So yes, 12.04 x 10^24 would be equivalent, but it also wouldn't be a correct mathematical representation.

Hi!!!! For the AQA TRIPLE CHEMISTRY spec, it states we need to know the reactions between group 1 with chlorine, oxygen and water. Previous exam Qs have asked what you observed when adding grp 1 metal with water. Could they ask what is observed when adding grp 1 metal with oxygen? chlorine? if so, what would be the observations be? ~~~~ Additionally, in unit 4 of the same spec (chemical changes), the spec states that we need to "recall and describe the reactions, if any, of potassium, sodium, lithium, calcium, magnesium, zinc, iron and copper with water or dilute acids." Do we need to know observations for ALL these metals when added with water and dilute acids (like what you observe when add the 2) If not, what exactly is this bullet point asking??? What will we be tested on from this bullet point? Thanks Thanks soooo much! :)

@DrdeBruinsClassroom

11 күн бұрын

They can, and they have. Oxygen makes alkali metals tarnish. Reaction with chlorine you start off with green gas, which disappears, and you see a bright light and then white crystals form (because you make salt). Yes, you need to know for all of them but basically you just see bubbles (if anything) and the number of bubbles is determined by how reactive it is. With water even Magnesium is incredible slow. With acid, you'll see Iron and zinc producing small bubbles but not copper

56:30

is there an acronym to remember the reactivity

@DrdeBruinsClassroom

Not an acronym but a mnemonic. Purple soda lemonade cans may also contain zebra idols that lead highlands cows somewhere greatly peaceful. (It's got some extra ones in there, but it's what my year 9s in 2017 came up with and I've stuck with it ever since 😅)

The different exam boards have different specifications, so the exams cover different things. Everything in here is correct Chemistry, but the Edexcel papers will also contain some content not covered in this video, and there are differences too in terms of e.g. what is Higher Tier only.
