Question

find the value of a for which the following system of linear equation has infinite numbers
(a-1) ×-y=5​

Answer 1

Step-by-step explanation:

Oxidation is a half reaction which cannot occur on its own. It must always be accompanied by reduction, which is a chemical reaction in which a molecule, atom or ion gains electrons. ... Hence, reduction and oxidation are complementary processes: as one compound is oxidised, another is reduced.
