The law of conservation of mass states that in any given chemical reaction, the total mass of the reactants equals the total mass of the products.. Chemical equations obey the law of conservation of mass. They show that all the atoms in the reactants are still present in the products.. Outline. Time Derivatives & Vector Notation. Differential Equations of Continuity. Momentum Transfer Equations. Introduction. FLUID. In order to calculate forces exerted by a moving fluid as well as the consequent transport effects, the dynamics of flow must be described mathematically . and Stoichiometry. Mole Ratio. Recall:. The coefficients . of a balanced chemical equation give the mole ratio of one chemical . to another. We can use these numbers to predict the number of moles of product produced. What happens in a Chemical Reaction?. Chemical . bonds. in the reactants are . broken. , then atoms are . rearranged. to form new substances (. products. ). .

Back to Combustion! . CH. 4. + 2O. 2. . → CO. 2. + 2H. 2. O. If 575 g of . methane . gas is combusted with 2300g of oxygen, 1150g of H. 2. O are produced. How much CO. 2. is produced? . Before we can solve this question let’s review an old concept you learned in grade 8!. What happens in a Chemical Reaction?. Chemical . bonds. in the reactants are . broken. , then atoms are . rearranged. to form new substances (. products. ). . The amount of . matter. does not . change. In a chemical reaction the total mass of everything at the end of the reaction is the same as the total mass at the beginning.. The Law of Constant Composition. However you make a compound, it always contains the same elements in the same proportions by mass.. In a chemical reaction the total mass of everything at the end of the reaction is the same as the total mass at the beginning.. The Law of Constant Composition. However you make a compound, it always contains the same elements in the same proportions by mass.. What is a thermal decomposition reaction? Can you given an example?. GOOD PROGRESS:. Recall the definition of ‘conservation of mass’. Explain conservation of mass in chemical reactions. OUTSTANDING PROGRESS:. Give an example of a non-communicable disease.. What is a pathogen?. Name the four types of pathogens.. Which pathogen is the usual cause of food poisoning?. Name another disease this type of pathogen can cause in humans..
