can u please tell me what topics from physics come in the ATP paper? (O-level) like in chemistry its mainly just Acids, Bases n Salts , Rate of reaction and Moles..
PLEASE HELP!

hey i have a question in chemistry.. do u know y copper cannot react with a dilute acid to form a salt?? i mean y do we have to change it to copperoxide or copperchloride?? plz reply ASAPthey absorb more heat energy from the hot water
Copper is quite low in the reactivity serieshey i have a question in chemistry.. do u know y copper cannot react with a dilute acid to form a salt?? i mean y do we have to change it to copperoxide or copperchloride?? plz reply ASAP
So its not just gonna be copper then right... i mean if they say silver or platnium the same rule applies?? and what if they are really high in the reactivity series? would we be able to make a salt?Copper is quite low in the reactivity series
So its not just gonna be copper then right... i mean if they say silver or platnium the same rule applies?? and what if they are really high in the reactivity series? would we be able to make a salt?Copper is quite low in the reactivity series
yes, includes all non reactive metals.So its not just gonna be copper then right... i mean if they say silver or platnium the same rule applies?? and what if they are really high in the reactivity series? would we be able to make a salt?
you can check out the syllabus for itcan u please tell me what topics from physics come in the ATP paper? (O-level) like in chemistry its mainly just Acids, Bases n Salts , Rate of reaction and Moles..

We know that R = ρL/AHey..ud any1 me in PHY PA.PA ............. Q11b in mj - p31 -2010 ...plz.plz1 !! any 1 ..i realy cnt understand it!!

Yes, the same rule applies with noble metals such as Platinum,Silver,Gold or those quite low in the reactivity series!So its not just gonna be copper then right... i mean if they say silver or platnium the same rule applies?? and what if they are really high in the reactivity series? would we be able to make a salt?
Could anybody explain to me why when we use step up transformer the current is reduced so we use thinner and lighter cable ? i can't get what the relation between the current and the cables.
thanksthe larger the current, the larger the heat losses.
since the current is reduced, thinner wires can be used, as the heat produced will be much less... so thin wires will not be melted.
paper 6 physics tips anyone ?
