At the end we stopped the distillation with some product left in the vial. Why is it considered unsafe come distill until dryness
See the mslsec.com below
Distillation is a process of separating the contents of a fluid mixture by making use of the difference in the boiling temperature of the contents of the mixture. As the boiling point of each component is reached, that evaporates off and the vapor is condensed and collected to give a pure product.

It is never advisable come distillate to dryness because permitting the content of the distilling flask to dry up can cause heat to damages the flask or in some too much cases, reason unintended chemistry reactions that might change the outcome of the experiment or reason laboratory accident.

Why carry out scientists use chemical equations
They basically use them to summarize what happens in chemical reactions
hope this helps :)

Find the potentials the the complying with electrochemical cell:
mslsec.com: 0.18 V
Here Cd undergoes oxidation by ns of electrons, therefore act as anode. Nickel undergoes reduction by gain of electrons and thus act together cathode.
Here Cd undergoes oxidation by loss of electrons, therefore act together anode. Nickel undergoes reduction by get of electrons and thus act together cathode.
Using Nernst equation :
n = variety of electrons in oxidation-reduction reaction = 2
Thus the potential that the adhering to electrochemical cell is 0.18 V.

Calculate E o cell because that the reaction: AgCl(s) + NO(g) → Ag(s) + Cl-(aq) + NO3-(aq) (in acidic solution) use the truth that the red
Let"s think about the complying with redox reaction.
AgCl(s) + NO(g) → Ag(s) + Cl⁻(aq) + NO₃⁻(aq)
We have the right to identify the oxidation and also reduction half-reactions.

Reduction (cathode): 1 e⁻ + AgCl(s) → Ag(s) + Cl⁻(aq)
Oxidation (anode): 2 H₂O(l) + NO(g) → NO₃⁻(aq) + 4H⁺(aq) + 3 e⁻
The standard cell potential (E°) is same to the difference between the standard reduction potential the the cathode and the standard reduction potential that the anode.
E° = E°red,cat - Ered,an = 0.22 V - 0.96 V = -0.74 V
