Balancing Chemical Equations Lab Welcome to It s Elemental Balancing Act Welcome to It s Elemental Balancing Act The computer will give you a number of incomplete chemical equations Balance the chemical equations by selecting coefficients from the pull down menus Once you think the equation is balanced press the Check my answer button Have fun and good luck
The ultimate goal for balancing chemical equations is to make both sides of the reaction the reactants and the products equal in the number of atoms per element This stems from the universal law of the conservation of mass which states that matter can neither be created nor destroyed Balance a chemical equation Recognize that the number of atoms of each element is conserved in a chemical reaction Describe the difference between coefficients and subscripts in a chemical equation Translate from symbolic to molecular representations of matter Version 1 1 10 For Teachers Teacher Tips

Balancing Chemical Equations PhET Interactive Simulations Method Balance each equation in the Data Collection and Processing section Use circles with atom or ion symbols to represent each atom or polyatomic ion If polyatomic ions stay together put the entire ion in a circle Build one molecule or formula of each reactant on the left tray and one molecule of each product on the right tray
The balanced chemical equation for the combustion of glucose in the laboratory or in the brain is as follows C 6H 12O 6 s 6O 2 g 6CO 2 g 6H 2O l Construct a table showing how to interpret the information in this equation in terms of a single molecule of glucose moles of reactants and products 2 2 4 1 2 2 1 4 4 4 yes A balanced chemical equation often may be derived from a qualitative description of some chemical reaction by a fairly simple approach known as balancing by inspection Consider as an example the decomposition of water to yield molecular hydrogen and oxygen This process is represented

N2 H2 NH3 On the left there is 2 N and 2 H On the right there is 1 N and 3 H If we tried to balance starting with H you d need to use a fraction or decimal and would get messy so let s start with N There s 2 on the left and 1 on the right so we need to change the coefficient of NH3 to 2 Now we have Balancing Equations The chemical equation described above in Figure PageIndex 1 is balanced meaning that equal numbers of atoms for each element involved in the reaction are represented on the reactant and product sides This is a requirement the equation must satisfy to be consistent with the law of conservation of matter
