Biology; Chemistry; Physics: Post your doubts here!

[snoonono]

Dont know why but XPF becomes more fun and addictive when the subject being discussed totally depends on General concepts(Physics and Biology) then MORE of a crammed subject(Chemistry).

I know most wont agree, but this is how I feel!

haha i agreeee

Technically speaking, one can predict the paper pattern for Science subjects.
They give 2 easy and 1 difficult paper! I know its a general perception! But over the years it hasn't happened!
Biology P1 and P6 were easy while P2 was tough!
We are done with Physics P1 and P2, both easy so there are high chances of P4 being tough!
And for Chemistry P4 was easy! Possibly P2 will surely be difficult!

So prepare tight everyone!
All I am trying to do is passing The Thought!

Its not necessary :| We cant really predict anything at this tym,it all depends on the examiners.....lets just prepare for the worst and hope for the best

yup that's the answer... but i got confused by the mixture. wat about that?? and how does the VOLUME of hydrogen produced differ?? reaction speed differ karey to smjh mein ata hai but volume to same nhi hona chahiye??

You answered your own question
Rate of reaction is the main point here.For the same time , magnesium will react quickly and yield more than zinc that reacts slowly. It's like the fast athlete will be able to complete 2 laps , while the slower athlete will only be able to complete 1 lap for the same amount of time . Simple concept hai Sister, don't confuse yourself!

As for the matter of mixture , well that is obvious! It cannot give maximum yield as part of both metals will be shielded by the other metal . And it won't give minimum as both metals are collectively reacting . So it would give yield of somewhere in between.

Oh GREAT!! I'm already fretting too much over chem and phy and u come along with ur insane predictions (no offence .... i'm just too upset ryt now) ... anyways plz don't say such stuff bro or u'll jinx us. just do what what smeone there said : hope for the best and prepare for the worst .. and keep ur mouth shut ( no offence again ) soorry if i offended u its just this phase u know!

Back to Topic now!

hahaa.... woww!! thanks God i didn't do anything to get that much insult. *phew*
Dukeofwin i wasn't getting scared .... i was just trying to show some respect in these not-so-deserving circumstances .... besides no one deserves that kind of battering to begin with we all have probably torn his hide off already.

Um actually relaxxxx.Abhi pichli dafa hi koi banda keh rha tha forum par k Physics will be difficult---but it was easy....So like I said we cant predict anything. Chill on dude

daredevil girl just relax and take it easy

yh thnks ... thats the same line my dad was using ryt now except that he wasn't calling me DAREDEVIL
