Answer: Aqua fortis is also known as Nitric Acid
Explanation: and the process in making aqua fortis is THE OSTWALDS PROCESS
detailed explanation by me
ammonia is also used in this process, which is reacted with oxygen and water and a catalyst platinum.
HOPE THIS HELPSS!!!
Answer:
Calibration curves are used to understand the instrumental response to an analyte, and to predict the concentration of analyte in a sample.
At the equivalence point, the NaF completely reacts with the HCl
The correct option that gives the equivalence point when titrating NaF solution with HCl(aq), occur at a pH value is option c);
c) <u>Below 7 because it is determined by HF (aq)</u>
Reason:
The ionic equation of the reaction taking place in the titration is presented as follows;
- Na⁺ (aq) + F⁻ (aq) + H⁺ (aq) + Cl⁻(aq) → HF (aq)+ Na⁺(aq) + Cl⁻(aq)
Therefore, by removing the spectator ions, we get;
Therefore;
The net ionic equation is the formation of hydrofluoric acid, HF, which is a
weak acid, therefore, the pH value will be <u>below 7 because it is determined </u>
<u>by HF</u>

Atomic mass Carbon (C ) = 12.01 a.m.u
12.01 g ---------- 6.02x10²³ atoms
1.50 g ----------- ??
1.50 x ( 6.02x10²³ ) / 12.01 =
7.51x10²² atoms of C
hope this helps!
Answer:
No of neutrons and protons decides mass of the atom. Electrons having negligible
mass are ignored.
Mass of atom
Mass of atom= sum of no of protons(Z) and neutons(N)
=Z+N
For eg:
In hydrogen atom,
Mass of H= Z+N
=1+0
=1 AMU
