Law of electrolysis was given by Faraday.
He discovered that,the amount of chemical change or decomposition is exactly proportional to the quantity of electricity that passes in solution,
Physical change can change a substance by affecting the form of a chemical change.
Examples of physical changes:
Something cut (Paper)
Molded (Bread)
Boiled (Water)
Mixed (Berries and strawberries)
HOPE THIS HELPS YOU! ^_^
The temperature rose. so kinetic energy increase. the answer is A. concentration will not affected
Make sure have same amounts of species on both sides
Cu (s) + 2 AgNO3 (aq) -> Cu(NO3)2 (aq) + 2 Ag (s)
