Question
1. The reaction between aluminum and iron(II) oxide can generate temperatures approaching 3000°C and is used in welding metals: 2A1 + Fe:(), Al:0; + 2Fe In one process, 124 g of Al are reacted with 601 g of Fe203. (a) Which is the limiting and excess reactant in the given reaction? (b)Calculate the mass (in grams) of Al203 formed. 2. The depletion of ozone (03) in the stratosphere has been a matter of great concern among scientists in recent years. It is believed that ozone can react with nitric oxide (NO) that is discharged from the high altitude jet plane, the SST. The reaction is: 0, - NO • 11: + NO: If 0.740 g of 03 reacts with 0.670 g of NO, how many grams of NO2 will be produced? Which compound is.the limiting reagent? 3. Consider the reaction: Mn(), + 4HC1 MnCl, + Cl, - 2H4) . .. If 0.86 mole of Mn02 and 48.2 g of HCl react, which reagent will be used up first? How many grams of Clz will be produced?
