Hopefully, In sha Allah.Oh hahaha either ways others in my class also got 4 So i guess you guess may be correct
Lol its okay ... thanks for the explanationSorry for the late reply, I doubt you need this anymore =P But, you only use the total abundance. For example if the relative abundance was 2 and 7, you will divide by 9.
for 1 mole of S203^2- to reduce 4 moles of Cl2 molecules it should give 8 electrons in order to form 8Cl^-Please help with this question
an aqueous solution contains 1 mol
of S2O32- ions and this reduces 4
mol of Cl2 molecules. What is the
sulfur containing product of this
reaction a) S (b)SO2 (c) SO32- (d)
SO42-. I cnt just come up with the
solution. Answer is D
A cannot be an answercan someone explain why it's D, and not the others

C says -2 x enthalpy change of formation of waterhttp://onlineexamhelp.com/wp-content/uploads/2014/08/9701_s14_qp_11.pdf
Question 3.......Help please!!!!!!!! The Ans is D
My doubt is why cant the answer be C????
Perhaps this will help you:Hey,
can anyone upload solved paper 5 questions(graph questions)
-the construction lines part that is and finding out the equations to be used.
thank you.
q2 is BOct Nov 2003 paper 1
Can anyone explain Q2,3,15 and 20 ??
Q15 - see the ones which will decomposeOct Nov 2003 paper 1
Can anyone explain Q2,3,15 and 20 ??
Omg someone replied so fast khud hi solve kr lia thaq2 is B
30%=mass of P2O5
? = mass of P2
cross multiply to get the answer
Tysm. .Q15 - see the ones which will decompose
B - MgCO3 -----> MgO + CO2 ---- u are getting one mole ov a gas which means its 24dm3
C- 2Mg(NO3)2 ------> 2MgO + 4NO2 + O2 ---- here its 5 moles of gas
Q20 -try out the structures....thats the only option
if u dont get it tell me
Q3-- its easy
write the equation first
C6H12 + 9O2 ------> 6CO2 + 6H2O
find the mass of CO2 nd H2O
6CO2 = 108
6H20 = 264
108/264 = .41
maine pehle dekha nhi thaOmg someone replied so fast khud hi solve kr lia tha
most welcome love :3Tysm. .
ur boss is having some doubts in phy mcqs and p2 so I need some help in them
