In this last example, we did the calculation in two steps. However, it is mathematically equivalent to perform the two calculations sequentially on one line: The units still cancel appropriately, and we get the same numerical answer in the end. Sometimes the answer may be slightly different from doing it one step at a time because of rounding of the intermediate answers, but the final answers should be effectively the same. Example 10 How many moles of HCl will be produced when g of AlCl3 are reacted according to this chemical equation? The molar mass of AlCl3 is From the balanced chemical equation, we construct a conversion factor between the number of moles of AlCl3 and the number of moles of HCl: Applying this conversion factor to the quantity of AlCl3, we get Alternatively, we could have done this in one line: The last digit in our final answer is slightly different because of rounding differences, but the answer is essentially the same.

Practice Grade 5 Unit 5 Week 3 Answer Key
Test Yourself How many moles of Al2O3 will be produced when The steps are the same but are performed in reverse order. Example 11 How many grams of NH3 will be produced when Start by using the balanced chemical equation to convert to moles of another substance and then use its molar mass to determine the mass of the final substance. In two steps, we have Now, using the molar mass of NH3, which is It should be a trivial task now to extend the calculations to mass-mass calculations , in which we start with a mass of some substance and end with the mass of another substance in the chemical reaction. For this type of calculation, the molar masses of two different substances must be used—be sure to keep track of which is which. Again, however, it is important to emphasize that before the balanced chemical reaction is used, the mass quantity must first be converted to moles.

Expect it to be on your test. Second comment before starting: What is the Limiting Reagent? It is simply the substance in a chemical reaction that runs out first. It seems to be a simple concept, but it does cause people problems. Let's try a simple non-chemical example. Reactant A is a test tube. I have 20 of them. Reactant B is a stopper. I have 30 of them. Product C is a stoppered test tube. So now we let them "react. Step by step we use up stoppers and test tubes the amounts go down and make stoppered test tubes the amount goes up. Suddenly, we run out of one of the "reactants. We run out of test tubes first. Seems obvious, doesn't it? We had 20 test tubes, but we had 30 stoppers. So when the test tubes are used up, we have 10 stoppers sitting there unused. And we also have 20 test tubes with stoppers firmly inserted. So, which "reactant" is limiting and which is in excess?
