D. Membrane. Can also be called cell membrane so you don't get confused with the nucleus's membrane/envelope!
Answer:
The Equations sort each listed half reaction as either an oxidation or a reduction.
Fe + CuSO4 + → FeSO4 + Cu
(Fe oxidized, Cu reduced)
Explanation:
For proper understanding of the concept of the Redox reaction, let us know the meaning:
Reduction- Oxidation or "redox" reactions occur when elements in a chemical reaction gain or lose electrons. This reaction causes an increase or decrease in oxidation numbers. The Half Equation Method is used to balance these reactions. The equation is separated into two half-equations, one for oxidation and one for reduction. For Example -
CuO + H2 → Cu +H2O.
In this redox reaction, CuO is getting reduced to Cu since Oxygen is getting removed.
Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s) Oxidation state of Fe changes from 0 to +2 and oxidation state of Cu changes from +2 to 0.
Huh? What is the question
What is waste water treatment ?
“The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment.”
