hi you all, am searching for chemistry p4 topical past papers for chemistry of live, applications of analytical chemistry and design and material
We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

What will react differently with the two isomeric pentanols, (CH3)3CCH2OH and (CH3)2CHCH2CH2OH?
A acidified aqueous potassium manganate(VII)
B concentrated sulphuric acid
C phosphorus pentachloride
D sodium
Why is it B? Both are primary alcohol, should it both become Alkene?

Ya............independent variable is da one u r changing n dependent variable is a 1 that is supposed 2 b kept constant!will anyone tell me about the tips of paper 5 n dependent ,independent variable
these quations are given in data booklet so no need to memorize itA solution of Sn2+ ions will reduce an acidified solution of MnO4– ions to Mn2+ ions. The Sn2+ ions are oxidised to Sn4+ ions in this reaction.
How many moles of Mn2+ ions are formed when a solution containing 9.5 g of SnCl 2 (Mr: 190) is added to an excess of acidified KMnO4 solution?
help plzzzzzz
actually u might know water is amphoteric oxide and sulfuric acid is an acid this settles it i think u might be confused with 331 Which statements are correct in terms of the Brønsted-Lowry theory of acids and bases?
1 Water can act as either an acid or a base.
2 Sulfuric acid, H2SO4, does not behave as an acid when dissolved in ethanol, C2H5OH.
3 The ammonium ion acts as a base when dissolved in liquid ammonia.
Answer is 1 only, why?
