In this simulation, select the sandwiches icon where you can set the number of bread slices, cheese slices, and meat slices to prepare a sandwich. you can then move to the molecules version where you will be able to relate the analogy to one of three specific chemical reactions. a) in the sandwiches mode, select the "cheese sandwich" option and observe the equation given for the preparation of a cheese sandwich. when the number of bread slices and cheese slices is set to "0," you will see that there is "no reaction." now, in the equation, set the number of bread slices to "2" and the number of cheese slices to "1." you will see that the product formed by these three elements is one cheese sandwich with two slices of bread and one slice of cheese. this equation can be written as2 bread + cheese → cheese sandwichclassify the following combination of bread and cheese according to the limiting ingredient in the preparation of the cheese sandwich mentioned above. b) in the sandwiches, mode select the "cheese sandwich" option and observe the equation given for the preparation of a cheese sandwich. in the equation, set the number of bread slices to "2" and the number of cheese slices to "1." you will see that the product formed by these three ingredients is one cheese sandwich. suppose you have 44 bread slices and 34 cheese slices. how many cheese sandwiches can you make? c) go to the molecules mode by selecting the icon at the bottom. notice that there are three real reactions: the synthesis of water, the synthesis of ammonia, and the combustion of methane. select each of the reactions, and observe the reactants taking part in the reactions. suppose you are carrying out each of these reactions starting with 5 mol of each reactant. observe that some reactants are in excess whereas some reactants limit the amount of products formed. classify each of the reactants as a limiting reactant or an excess reactant for a reaction starting with 5 mol of each reactant. d) find the number of moles of water that can be formed if you have 118 mol of hydrogen gas and 54 mol of oxygen gas.
