anonymous · Answer

i dont get this at all :\

ghazi · Answer

well, ionic: Na2O ,siO2 and NaNO3 
covalent :C2H6 , CO2, N2O5

ghazi · Answer

rest is metallic and diamond is covalent

anonymous · Answer

can i get a little explanation though?

phi · Answer

Google works http://www.diffen.com/difference/Covalent_Bonds_vs_Ionic_Bonds It looks like one major clue ionic is between a metal and a non-metal covalent is between two non-metals

anonymous · Answer

and isnt $\text{SO}_2$ covalent?

ghazi · Answer

yes SO2 is covalent

anonymous · Answer

@phi yea thanks i get that now! :)

anonymous · Answer

Thanks guys! :D

anonymous · Answer

what is the difference in reaction between a substance in solid state and a substance in liquid state?

anonymous · Answer

@ghazi

ghazi · Answer

well basically in solid state reaction its not a reaction actually its a quasi static process  like rusting of iron

ghazi · Answer

and if we talk about liquid state reaction like adding two chemicals in liquid state its a reaction where we can obtain product very fast , may be enthalpy of reaction could be very high and catalyst can alter rate of reaction very fast and  so on but state of reactant would be liquid lol

anonymous · Answer

okay well my question says:

Circle ALL the compounds in the following list which would be expected to form inter molecular hydrogen bonds in the liquid state:
$$CH_3OCH_3~(dimethyl~ether)$$$$CH_4$$$$HF$$$$CH_3CO_2H~(acetic~acid)$$$$Br_2$$$$CH_3OH~(methanol)$$

anonymous · Answer

wait let me guess at this

anonymous · Answer

the 3rd and last one....?

ghazi · Answer

inter molecular hydrogen bond is formed in  compounds containing  H and highly electronegative atom

anonymous · Answer

so am i right?

ghazi · Answer

that is dimethly ether, HF and acetic acid

ghazi · Answer

clear?

anonymous · Answer

but i was told that hydrogen bonds only occur when Fluorine, Oxygen, or Nitrogen, is DIRECTLY bound to Hydrogen

ghazi · Answer

yes, so just see in the compound acetic acid there is a bond of hydrogen and oxygen

anonymous · Answer

not directly though

anonymous · Answer

@nincompoop  the second question..

ghazi · Answer

but there will be formation of intermolecular H bond

ghazi · Answer

let me draw this
