Sir, this may sound like a silly question, but for a question 4ciii), can we say decreases instead of decrease?

[@MrKhing]

Yes it is the same no worries 😊

[@mayaadil7471]

@@MrKhing sir, in question 7d) the marking scheme says that one of the answers is catalytic addition instead of hydration. If we write hydration, will it still be accepted

[@xdgaming952]

@@mayaadil7471 i think it is hydration itself, i checked my notes

[@mayaadil7471]

@@xdgaming952 yeah, I was just making sure because of what the marketing scheme said. Thank you

Hey! great job, good practice i got before my exam. just 15:14 you forgot to write 4.16g which confused me

[@hayyyann4336]

hi teacher is it 20:58 the empirical and molecular formula relative molecular mass are always the same? just formula different?

[@hayyyann4336]

sorry I don't understand this part 22:08

[@MrKhing]

empirical formula shows simplest whole number ratio, molecular formula shows actual number of atoms of each elements in the compound.
