1.53 g of aluminum metal is placed in a Erlenmeyer flask with 1.5 M sulfuric acid. The hydrogen gas produced from the reaction is collected over water as seen in the diagram below. The aluminum is allowed to react with the sulfuric acid until it stops reacting. There is still some unreacted aluminum left in the reaction flask. The gas in the collection flask is brought to the same atmospheric pressure as the surroundings, 765.25 torr and a temperature of...

Sulfuric acid dissolves aluminum metal according to the following reaction: 2Al(s)+3H2SO4(aq)-----=Al2(SO4)3(aq)+3H2(g) Suppose you wanted to dissolve an aluminum block with a mass of 14.9g . What minimum mass of H2SO4 would you need? What mass of H2 gas would be produced by the complete reaction of the aluminum block? Express your answer in grams.

4. Consider the reaction of aluminum and oxygen: Al(s) + O2(g) Al2O3(s) (i). Which is the limiting reactant if we start with 30.0 g Al and 30.0 g O2? (ii). What is the Theoretical Yield for the reaction? (iii). If 25.85 g of Al2O3 was collected at the completion of the reaction (actual yield), what is the % yield for the reaction? 5. (a). A 1.506-g sample of limestone-containing material gave 0.558 g of...

9. (Basically the same reaction as #8 above, without some of the assumptions) In one experiment, a student placed 50.0mL of 1.00M HCI at 25.5°C in a coffee-cup calorimeter. To this was added 50.0mL of 1.00M NaOH solution also at 25.5°C. The mixture was stirred, and the temperature quickly increased to a maximum of 32.2°C. 2pts a Provide a thermochemical reaction, including AH in kJ. (include sign) b. What is the energy (AH)...

Microscale techniques: In today's experiment we will be using very small amounts of chemical reactants. This method is generally less expensive and more environmentally-friendly than traditional "test tube" chemistry. Some of the waste products produced in today's experiment, particularly those containing lead and barium, are harmful to the environment. By using such small amounts of chemical reactants we generate far less waste than by using larger scale methods. Procedure 1. Put on your safety goggles. Be sure to wear them...
