The oxidation state of Cl in `HClO_(4)` is +7.Apr 17, 2022
3ans. CrS+2No3 --) 2No+So4+cr^3+
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.
in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
