um....in the conquering textbook it said
"there are no degrees of strongness for strong acids"
which means u can't compare the strongness of HCK and H2SO4, they both strong and they both fully ionised.
but u can said H2SO4 has lower pH and has a greater H+ concentration as it is diprotic...
1.) amphiprotic = something can either act as acid or base (either donate or accept protons)
amphiteric = something can either react with acid or base
try to remember....amphi = both, pro = proton, thus amphiprotic = eith donate or accept proton
2.) when NaOH is added, the carbonate acid will...
lol sounds like my physics teacher, my phy teacher just gives us handout and ask us to read it and do exercise....then he walks out to do other stuffs.....he stays in class in class for 1/2 hour per WEEK in average....hopeless....:jedi:

So I found the tsfx was very helpful, and i am able to...
a.) Hydrogen
b.)
G of petrol: 0.69 X 80000 = 55200g
n = m/MM = 55200/114 = 484.21 mol of petrol has combusted
energy released: 5460 X 484.21 = 2643786.6 kJ = 2.64 X 10^6 kJ
c.)
n required for 2.64 X 10^6 kJ : 2.64 X 10^6 / 285 = 9263.16 mol
V = n X MV = 9263.16 X 24.79
= 229633.74...
