Copper metal can reduce silver ions to metallic silver. The copper is oxidized to copper ions according to the reaction A copper strip with a mass of 2.10 g is dipped into a solution of AgNO3. After some time has elapsed, the copper strip is coated with silver. The strip is removed from the solution, dried, and weighed. The coated strip has a mass of 4.89 g. What are the masses of copper and silver metals in the strip?
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
Copper metal can reduce silver ions to metallic silver. The copper is oxidized to copper ions according to the reaction
A copper strip with a mass of 2.10 g is dipped into a solution of AgNO3. After some time has elapsed, the copper strip is coated with silver. The strip is removed from the solution, dried, and weighed. The coated strip has a mass of 4.89 g. What are the masses of copper and silver metals in the strip? (Hint: Remember that the copper metal is being used up as silver metal forms.)
2Ag+ (aq) + Cus --> Cu+2 + 2Ag
Mass = ___g
Mass = ___ g
