    The language barrier can be an issue so I'd like to help in a way
    According to the State of Division if Calcium carbonate in Q2 of the tutorial 1:14:00
    When they say:
    Granules - think sugar and salt
    Lumps - think things like rocks (countable things)
    Powder - think grandpa and baby powder
    Hope this helps

      Please be courteous to your educators. We have a lot of pressure on our shoulders. Please remember they are doing their absolute best to help move your life forward. In fact, next time give them a virtual hug (to observe COVID protocols) and say thank you.
      I will continue, in partnership with all the educators around the country to give you all the service you re quire to do well.

    Unpopular Fact : Mr Mlungisi Is the best😃😃.
    Anyway guys when you come across a question asking you to calculate the rate, just treat the term rate as a term gradient. No matter how they twist the question the rate will always be ∆Y/∆x.

  • @MutaliMbambangani
    @MutaliMbambangani 8 หลายเดือนก่อน +1

    You said that when calculation reaction rate, it's change in something over change in time.
    So what other things should i expect to use when calculating reaction rate, and why did you choose the number of moles in this particular question?

    • @lizzolisa9068
      @lizzolisa9068 7 หลายเดือนก่อน

      You look at the SI units...if it's mol.s, then it means they used the number of moles....it can be volume concentration and mass

  • @phomedisebatane7955
    @phomedisebatane7955 3 ปีที่แล้ว +3

    Evening Mr Nkosi, Very illuminating lesson thank you, a bit of clarity the definition of a catalyst and a positive catalyst from listening to you to me they sound the same, also the definition that you provide for a negative catalyst conflicts the definition you provided of a catalyst, I'm a bit lost in that regard.

    • @MlungisiNkosi
      @MlungisiNkosi  3 ปีที่แล้ว +1

      Thank you for the feedback. Apologies for the confusion. I probably made the classic error of assuming every catalyst is a positive catalyst. It's honestly unintended...
      A catalyst either speeds up or slows down the rate of a reaction by either lowering (in the case of positive) or increasing (in the case of an inhibitor) the activation energy needed.
      A positive catalyst ONLY speeds up the reaction rate.
      An inhibitor ONLY slows down the reaction rate.
