Buffer is formed from weak acid and its salt with strong base (conjugate base) so the correct answer will be 0.1 M HCN and 0.1 M LiCN and all other choices are incorrect
Answer:- Fe changes from 0 to +3 and O changes from 0 to -2.
Explanations:- As per the rules for oxidation numbers:-
(1) Oxidation number of an atom in its elemental form is zero. Both the reactants Fe and are in their elemental forms and so the oxidation numbers are zero.
(2) Oxidation umber of oxygen in it's compounds is -2. Let's say the oxidation number of Fe in the product is .
Also, the sum of oxidation numbers of all the atoms in a compounds is zero. So:
So, the oxidation number of Fe in is +3 and the oxidation number of O is -2.
Hence, the oxidation number of Fe changing from 0 to +3 and O is changing from 0 to -2.
In terms of oxidation and reduction, Iron is oxidized and oxygen is reduced.
Yes. Price should be a factor that you consider
One chemical property would be reactivity of a particular substance.
The enzyme that catalyzes the following reaction is a hydrolase:
A–B + H2O → A–OH + B–H
- A–B is a chemical bond of unspecified molecules.
<u>Explanation</u>:
- Hydrolase is a compound that regularly proceeds as biochemical impetuses that utilize water to break a chemical bond, that is breaking a larger molecule into smaller once. Some basic instances of hydrolase proteins are esterases including peptidases and nucleosidases. Nucleosidases hydrolyze the bonds of nucleotides.
- Hydrolase proteins are significant for the body since they have degradative properties.
- Names of hydrolases are shaped as "substrate hydrolase." However, regular names are ordinarily in the "substrates". For instance, a Lipase is a hydrolase that breaks down fats and lipoproteins.
