Using the Law of Conservation of Mass, answer the following questions. If you need to review this concept,select here. A chemical reaction occurs in a closed system to observe and test the Law of Conservation of Mass. A piece of copper metal is placed in a silver nitrate solution in an Erlenmeyer flask. The flask is stoppered, weighed, and observed. The reaction that occurs is Cu(s) + 2 AGNO3(aq) – Cu(NO3)2(aq) + 2 Ag(s). Once the chemical reaction was complete, the system was weighed again. The mass of the reactants is measured to be a total mass of 142.5 g. After the reaction is complete, what will be the mass of products formed? Record only your final answer with the correct number of significant digits and proper units.

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.
