Answer:
electrolysis is the process by which electric current is passed through a substance to effect a chemical change
Answer: C) a redox reaction that produces an electric current
Explanation:
Chemical cell is a device which is used for the conversion of the chemical energy produced in a redox reaction into the electrical energy. The cell consists of the negative terminal called as anode where oxidation takes place and a positive terminal called as cathode where reduction takes place.

<span>Condensation takes place when gas molecules lose heat and kinetic energy. The warmer molecules are the faster they move. Gas molecules move very quickly and have a lot of kinetic energy and heat energy. As the gas molecules lose heat they also lose kinetic energy. As the molecules slow down they move closer together to form liquids.</span>
levels greater than seven are bases
levels on 7 are neutral
levels low than 7 are acids
there are 14 levels, Acids change litmus paper red and Bases change litmus paper blue.
Answer: because of isotopes
relative atomic mass =(75/100 × 35) + (25/100 × 37) = 35.5
isotopes of any element behave the same chemically because neutrons do not have any charge
