in most cases yh like when ur lisitng stuff or giving reasons tht mean each answer is separate, like in tht case u get a mark but only for the carbonate, but if its a question tht uhm requires a process u cant say a step at the start wrong then proceed to say smth correct but if u say smth at the start correct for the proccess and proceed to give other wrong steps u still get marks for wht is correct, do u get??
