In an acid base titration (for example a strong acid and strong base like HCl and NaOH), at equivalence point, the number moles of acid is equal to the number of moles of base.
HCl + NaOH ---- NaCl + H2O
Moles of Acid = Moles of Base
V(HCl) * M(HCl) = V(NaOH)*M(NaOH)
Now, beyond the equivalence point as more acid is added, the resulting pH will depend on the excess acid present.
Answer:
A group of cells doing the same job forms a tissue. A group of tissues working together forms an organ. Organs work in groups, too. A group of organs doing the same job is called a system.
Explanation:
Answer:
2 moles of HNO3
Explanation:
The equation seems to be balanced correctly. The problem is we done know what you started with. We will assume it is 3 moles of NO2.
If that is the case then 2 moles of HNO3 will be produced.
