QUOTE(neorelated4 @ Nov 1 2008, 03:53 PM) CuSO4 is soluble salt. D is definitely not possible.. this is no double decompostition reaction. Yup you are right, answer given is CA is not possible because Hydrogen is more reactive than copper metal. I would choose C. to get CuSO4 there are 3 ways. copper oxide with sulphuric acid, copper hydroxide with sulphuric acid or copper carbonate with sulphuric acid.  just wanna try asking here cuz cant find explanation in my books. Thx btw, CluelessNick, its your Bday right? Congratz  |

QUOTE(SticH @ Nov 5 2008, 08:52 PM) I never used pen for my add math paper, from form 4 untill now, still using the old school way. QUOTE(Leto Kynes @ Nov 5 2008, 09:01 PM) I've always used pencil for maths and add maths too. Makes your life easier because you frequently have to erase wrong answers/working. Imagine you have 1 minute left and you have to wait for your correction fluid to dry..   Walao.... I only just considering using pencil to write my answers but u guys do it often... SticH somemore did it since form 4... U not scared your teacher minus your marks? |

Can we answer it in table form? |
