Ans is A
When the temp. rises, the average kinetic energy of the molecules also increases. So the peak of the graph shifts to the right.
i think bcoz according to the bronsted-lowry theory bases are proton acceptors and here it is right ... if u feel any other option correct...u can put tht doubt forward too.!
thxx
Correct! I agree
A very simple question:http://www.xtremepapers.com/CIE/International A And AS Level/9701 - Chemistry/9701_s02_qp_1.pdf
pls explain hw do u get D for q2??!!
thankyouA very simple question:
Empirical formula mass = 30
No, of moles of carbohydrate = 1.8/30 = 0.06
The equation is:
(CH2O)n + (3n/2) O2 --> nCO2 + nH2O
So molar ratio of carbohydrate to CO2 is 1:1
It means No. of moles of CO2 = 0.06
mass of CO2 = 0.06 * 44 = 2.64
Thats why it is D
well... i would do it like this:
Oh yeah! I didn't think about this. *facepalm* Thank u saudha!
