Matter is neither created nor destroyed in a chemical reaction. Thus, the mass of the products of a chemical reaction must be equal to the mass of the starting materials. Formally, this concept is called the law of conservation of mass. A sample of sodium reacts completely with 0.426 kg k g of chlorine, forming 702 g g of sodium chloride. What mass of sodium reacted?
During a filtration or distillation experiment, we separate a mixture into its individual components. Do the chemical identities of the components of the mixture change during such a process? Explain.

- There are quite a few pieces of information we can glean from a chemical formula. The first is the mass of that formula. In looking at the periodic table, we know that each element has its own mass. When we combine that information with how we interpret how many of each element there is in the formula that we just went over, we can calculate the mass of the compound. Using glucose as an example: C6H12O6 tells us that glucose has 6 carbons, 12 hydrogens and 6 oxygens. On the periodic table, carbon has a mass of 12 g, hydrogen has a mass of 1 g, and oxygen has a mass of 16 g (I've rounded for ease. There will be times you use the entire mass provided on the table and times you won't -you'll know when). C = 6 x 12g = 72g H = 12 X 1g = 12 g O = 6 X 16g = 96g Add these values together and you get 180 g so glucose has a mass of 180 g. Calculate the mass of H2SO4.arrow_forwardAccording 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.arrow_forwardWhich of the following is not a consequence of the Law of Conservation of Matter? It provides a basis for balancing chemical equations. It means that there will be no observable change in the quantity of matter during a chemical reaction. As a result, there will be the same number of moles on both the reactant and the product side of a balanced equation. It can be stated as “matter is neither created nor destroyed during a chemical reaction.arrow_forward
