ANSWERING ALL BIO/CHEM PAPER 1 DOUBTS :)

[сᴏᴏʟ сяуѕтᴀʟѕ]

do u want me to post the question paper?

really sorry for so late reply

well..the answer is iron...slag comes out from the slag notch which is below the 'hot air in' thingy!
get it?
basically slag is on top of iron..

 

[MaRyy xD]

1/5th i.e 20% of oxygen is present in the air and for nitrogen 4/5th i.e 70% approximately.....so
1/5*starting volume of the sample of air=final volume of air
1/5*x=30
x=30*5
x=150 cm^3

Hope u got it

Heeeey thanks alot D
God bless ya

98 nov q15...maybe A cauz it's still a solid (I mean not crushed ) so if the piece is smaller there will be less s.a, while when larger there will be more particles....maybe...
cauz they r talking only about the surface changing.....

yes about the surface area. increasing the surface area will speed up the reaction and more particles will be able to react
