1. Iron reacts with oxygen gas to give iron(iii) oxide, Fe2O3
a.) Write a balanced equation for the reaction
b.) If 2.68 g pf Fe reacts with excess oxygen gas, what mass of Fe2O3 will be produced?
c.) What mass of O2 is required for the reaction?
2. Aluminum chloride, AlCl3, is an inexpensive reagent used in many industrial processes. It is made by treating scrap aluminum with chlorine according to the following balanced equation: 2Al(s) + 3Cl2(g) --> 2AlCl3(s)
a.) Which reactant is the limiting reactant if 2.70 g of Al and 4.05 g of Cl2 are mixed?
b.) What mass of AlCl3 can be produced?
c.) What mass of the excess reactant is leftover when the reaction is completed?
3. How many grams of Ca are needed to produce 18 moles of Fe? The equation for the reaction is 2FeBr3 + 3Ca--> 3CaBr2 + 2Fe
4. What volume of oxygen at STP is necessary to burn 350.g of glucose? The equation for this reaction is C6H12O6 + 6O2--> 6CO2 + 6H2O
5. Nitroglycerin (C3H5N3O9) is a powerful explosive. Its decomposition may be represented by 4C3H5N3O9 --> 6N2 +12CO2 +10H2O + O2 this reaction generates a large amount of heat and many gaseous products. It is the sudden formation of these gases, together with their rapid expansion, that produces the explosion.
a.) What is the maximum amount of O2 in grams that can be obtained from 200. g of nitroglycerin?
b.) Calculate the percent yield in this reaction if the amount of O2 generated is found to be 3.55 g. What can you conclude about the quality of this experiment? Explain
6. For the reaction O2 + NO --> NO2 (unbalanced):
a.) What mass of NO2 is produced form the reaction 32.0g O2 and 60 g NO?
b.) What mass of the excess reactant is leftover?
a.) Write a balanced equation for the reaction
b.) If 2.68 g pf Fe reacts with excess oxygen gas, what mass of Fe2O3 will be produced?
c.) What mass of O2 is required for the reaction?
