2. +7
Explanation:
The oxidation state of Cl in `HClO_(4)` is +7.Apr 17, 2022
3ans. CrS+2No3 --) 2No+So4+cr^3+
Cr=1 Cr=1
S=1 S=1
N=1=2 N=1=2
O=3=6 o=5=6
now that is how it look and it is not balanced in oxygen so add 2 in the front of No3.
it will look something like this 2NO3. even if u add 2 in the fornt it is not balance so add again 2 in the No in second and it will look like this 2NO.
so now it is blance.

Answer is 14.5 g L⁻¹.
<em>Explanation;</em>
Here, the question says reduce the units as one.
The presented units are g/L. To reduce the units to one, what we can do is take L to the upper side.
This can be done according to the rules of indices;
1 / aˣ = a⁻ˣ
Like that, we can write 1 / L as L⁻¹.
Hence, the reduced unit is g L⁻¹.
But remember to keep a space between when writing two different units.
Actually, this is an unit for density.
<span>The ability of a substance to dissolve in another at a given temperature and pressure is: </span>solubility
Here's my reasoning:
There are two things that make up a solution:
A solute and a solvent.
The solute gets dissolved into the solvent (most likely water).
