But sir on question B 4 B(I) we have been asked to find the mass of the pure oxide ,not iron (iii) oxide but why we are finding the number of moles of both Fe and O
section A number 17 the answer is B sir hydrogen is collected by upward delivery and it is less dense than air …..the gas that is less dense moves upward
I acknowledge your explanation, sir.
Thanks very much sir I need some more❤❤❤❤
Thanks sir you are really helping me
C1 e , this is because solid carbon dioxide has weak inter molecular forces and high vapur pressure to enable direct transition from solid to gas
