When an atom or molecule loses an electron it is oxidized and the reaction is called oxidation, when an atom or molecule gains an electron it is reduced and this is known as reduction. Both oxidation and reduction are known as Redox reaction
Answer:
H2 P4 O1. Explanation: In order to calculate the Empirical formula , we will assume that we have started with 10 g of the compound.
Explanation:
Ripping a paper for sure, because it won’t change the paper’s chemical composition!
Answer:
3 Both mass and charge are conserved.
Explanation:
The equation of the reaction is;
Cu(s) + 2Ag+ (aq) → Cu2+ (aq) + 2Ag(s)
A redox reaction is an acronym for oxidation-reduction reaction. This refers to a reaction in which the oxidation number of one specie is increased while the oxidation number of the other specie is decreased.
This means that one specie looses electrons while the other specie gains electrons. Here, Cu(s) looses electrons while Ag+(aq) gains electrons from left to right in the reaction.
In a redox reaction, both mass and charge are conserved. This means that the total mass and charge on the reactants side is the same as the total mass and charge on the products side.
