How was chem p34

They asked for 2 anions na? so you had to say so4 and so3 (if you missed one, you'll lose 1 mark I guess)

How was chem p34

did they ask to identify 2 anions or only one anion? And did they give two different blanks for anions or just one? I can't remember whether I wrote only sulfate or sulfate/sulfite. If they gave 2 blanks like they did for cations then I wrote it properly..

Phys p12 and Chem p12- 9th and 10th June,2015 Tips!

K.E = constant because of constant rate P.E = consider the fact that internal energy = kinetic energy + potential energy. In this case since water is going down, some of the particles will definitely evaporate and thus as the state changes from liquid to gas , potential energy is gained.
