    PHYSICS PAPER 31 HELPP

    is it correct to say that the heat lost as radiation is low as the vacuum acts as an insulator and that heat lost by conduction is low as the distance the heat needs to travel is long as the tube is double glassed?

    guys the question of the soluble salt that was made by titration,the question that asked how to remove the indicator. in the question did he say that the volume of the acid needed to neutralise the base was NOTED or not?

    Chemistry DONE!!!

    in the question about magnesium salts,was the volume of acid needed to neutralise noted or not?
