Answer:
Explanation:
Hello,
In this case, since the reaction between HCl and NaOH is:
We notice a 1:1 molar ratio between the acid and the base, for that reason, in the equivalent point we find:
Thus, in terms of concentrations, we have:
Hence, we solve for the concentration of the acid to obtain:

Answer:
Aluminium (Al): (3*2)+(5*2)=16
Sulphor (S): (3*1)=3
Oxygen (O): (4*3)+(3*1)=15
Answer : 5100 KJ
Explanation : In the given reaction of
we can see that 2 moles of Al is producing -850 KJ of energy
so for 12 moles of Al we can calculate as;
12 moles of Al X
= -
5100 KJ
So, we can say that 12 moles of Al will need -5100 KJ of energy.
