(a)- Time
(b)- Heat produced(i guess)
(c)- Material
this is what I think, hope it helps
Answer:
C
Explanation:
When something is chemical it is warped into a completely new substance and when coal is burned it is new so it is definitely C.
Answer:
The concentration of HA is the same as concentration of H3O+ and A- produced.
Explanation:
The dissociation equation is given below:
HA(aq) + H2O (l) —> H3O+(aq) + A-(aq)
From the reaction above, we can see that the acid is monoprotic acid i.e it has only 1 ionisable hydrogen atom.
Now, from the balanced equation, we can see that the acid produced equal concentration of H3O+ and A-.
This account for the reason why the bars for H3O+ and A- have the same height as the bar for HA.
9 is B
6 is A
i’m not sure about the rest
