need help with s09 q5b...
no problem.. anywaysthe vol. of phosphate soln used in cm3 is half the height of the ppt in mmalso at 8cm3 all the soln is used up. tht is because adding more does not increase the height of the ppt meaning there was no further reaction on adding more.also the formula is T3(PO4)2-----becauseu take it as 12cm3 of T nitrate react with 8cm3 of sodium phosphate (thts wen all the reactants r used up)so.....12:8...simplify it12:86:43:2and therefore u get T3(PO4)2
This is AN OLDDDDDD paper with a teacher MS that says Hydrogen and Chlorine are produced.
That's what the book says If you find a similar question, it'll be easier to compare and check if they ALWAYS mean aqueous=conc
Hey guys, another doubt, what are macromolecules? Are they the same as polymers?? And also can acidified potassium manganate (vii) be decolourised by an alkene? Thanks once again..
Macromolecules are substances with large molecular structure; like silicon, diamond, etc..And yes, potassium permanganate is decolorized when added to an alkene. (purple-->colourless)
Oh kay, so macromolecules have nothin to do with polymers?? and thank you..
Macromolecules are defined as made up of many smaller units- monomers.So polymers ARE macromolecules.What AF told you is ANOTHER definition of macromolecue.
Not all macromolecules are polymers.But all polymers are macromolecules
