13:57 Reaction is not *complete*

[@Tsuuyoka]

But the HCL is in excess...so why do we use burette to measure. Why can't we use measuring cylinder?

[@yez276]

As the acid is very concentrated and you are adding it throughout the experiment (if conc safer in burette)

Aren’t we supposed to change the 62’C to Kelvin in 1(g) 15:50

[@f.r.i.e.n.d.l.y]

The 62C is the change in temperature (final-intial temp) if you change both final and initial temp from C to K and subtract you'll still get 62

15:39 where is the 0.050 from?

[@Leo.tae17]

the mole of cao used look in step one ....the same mole is used for experiment two

[@nikrayyannikhalmey3504]

@@Leo.tae17 but mole ratio of CaO to HCl is 1:2? so shouldnt it be 0.05 x 2 = 0.1mol? I might be wrong

[@richierichard7]

Hello for chemistry p5 or in general is it as strict as physics for number of sf or can leave final answer to 4-5 sf?

[@CamScience]

@@richierichard7 they may mark u for such answers but it is prefered to use 3sf
