Chemists generally use the term atomic weight rather than average atomic mass. We state in the text that the latter term is more correct. By considering the units of weight and mass, can you explain why this is so? The response has to be a narrative, in the form of a paragraph showing work (mathematics) wherever applicable. This paragraph should be at least 10 complete sentences. These sentences must be explaining your answer. please type the answer
According to the law of conservation of mass, which statement about chemical reactions is always true? The number of atoms of each element in the reactants is the same as the number of atoms of each element in the products. The states of the substances in the reactants is the same as the states of the substances in the products. The number of substances in the reactants is the same as the number substances in the products. The number of molecules in the reactants is the same as the number of molecules in the products.

You take three compounds, each consisting of two elements (X, Y, and/or Z), and decompose them to their respective ele- ments. To determine the relative masses of X, Y, and Z, you collect and weigh the elements, obtaining the following data: a. What are the assumptions needed to solve this problem? b. What are the relative masses of X, Y, and Z?c. What are the chemical formulas of the three compounds? d. If you decompose 21 g of compound XY, how much of each element is present? I am requesting to have this equation simplied for I am not sure where the 15 comes from in the equation. How can one find the chemical formulas? Where does the 4.2 and the 0.4 come from? Why are the mases of X and Y multiplied with 1/5?
