    I dont think theres anyone who's a master in physics..... If it all you would have to go crazy to master that subject. I am satisfied getting about 35 for paper 1, 65+ for paper 2 and at least 25 for atp:D

    Yep, it should be cause in reflux you have a vertical condenser to prevent escape of the alcohol

    That is correct. But the empirical is P2O5.

    19th is A since aluminium oxides are amphoteric and carbon dioxide is acidic so they would react with NaOH. Copper and magnesium oxides don't react with bases. 20th is B since if you add more HCl then t pressure on the reactant side increases and is more than that of the product side so eq...

    Or else here's a more mathematical approach. Any compound must have zero overall charge (fact) So we take phosphorus's charge as x. Then 2x + (5*-2) = 0 2x-10=0 X=+5 This is the way to find the oxidation state of an element in a compund

    You have the answer in the question itself. It says Phosphorus (V) which means that its oxidation state is +5. We know for sure that oxygen has an oxidation state of -2. Therefore using the basic valency rules we just swap the charges of the 2 elements and we get P2O5. Hope you understand!
