dude i am answering his question""should they be an oxide of metal" however u r yte on the point that metal oxides are basic and non metal are acidic oxides????
Well what do u mean by the bold words above !
Metal oxides act as bases while non metals act as acids and only amphoteric oxides act as both so it wud be better !
Actually there are some substance like iodine, ammonium chloride etc which can sublime while all others can only melt.Therefore u need to know the chemical substance is a sublimate or not.how do we know if an element is going to melt or sublime?
n what is the conversion of gas directly into solid form called?
it sure did. thnkuuuActually there are some substance like iodine, ammonium chloride etc which can sublime while all others can only melt.Therefore u need to know the chemical substance is a sublimate or not.
To the second question the process which converts gas into solid directly is called solidification!!
Hope this help!!

umm in the explanation of neutralization reaction here, there are two equations given. one has the products salt n water. other has salt, water n carbon dioxide gas.can any1 tell me wht are the different circumstances? in both cases bases have reacted with acids.
help plzzzz??? n soon
thanku
hmmm i think not, where did the Cl go?so wherever carbonates react with acid they form salt, water and CO2?
is this reaction correct? HCl + CaCO3 > H2CO3 + H2O + CO2
btw, thanku
opppsss yea rythmmm i think not, where did the Cl go?
I think this will be the correct oneso wherever carbonates react with acid they form salt, water and CO2?
is this reaction correct? HCl + CaCO3 > H2CO3 + H2O + CO2
btw, thanku
yes it does, when Acid reacts with Bases.thankuu
n wht about the CO2 thng? its released in every reaction tht has carbonate reacting??
ofcourse, an easy way to do itheyy,umm are we supposed to memorize the reactivity series?
