    Chemistry paper SO EASYY!!

    what were the options? I dont remember that question.....

    yea but if it has 2 functional groups then the same reason why it has both the charecteristics of the homologuous series.....so to be precise the answer should be a different homologuous or no homologuous but since there was no option of no homologuous its both

    no there was 24% oxygen whereas on earth its only 20%....so its oxygen and Co2 yr right..... I put only CO2 that was such a silly mistake D:

    Chemistry paper SO EASYY!!

    Why would u need a measuring cylinder when the acid was added in excess?? The magnesium had to be weighed and thats it.....so I put C....

    Chemistry V1 (discussion)

    I agree with all the answers except the one with the measuring thing we did not need a measuring cylinder coz we needed balance to weigh the magnesium, thermometer for temp and like something else but we did not have to measue the liquid as we just added it in excess....so I put C and I hope its...

    What are the different amphoteric oxides we need to know for CIE IGCSE? What are the different unreactive oxides we need to know for the CIE IGCSE? Thanks
