aluminium oxide is extracted from aluminium oxide as shown calculate the mass of aluminium that can be formed from 1020g of aluminium oxide
Chlorine can be prepared in the laboratory by the reaction of manganese dioxide with hydrochloric acid, HCl(aq), as described by the chemical equation
MnO2(s)+4HCl(aq)⟶MnCl2(aq)+2H2O(l)+Cl2(g)
How much MnO2(s) should be added to excess HCl(aq) to obtain 245 mL Cl2(g) at 25 °C and 715 Torr?
7.30 L container holds a mixture of two gases at 43 °C.
43 °C. The partial pressures of gas A and gas B, respectively, are 0.272 atm
0.272 atm and 0.859 atm.
0.859 atm. If 0.210 mol
0.210 mol of a third gas is added with no change in volume or temperature, what will the total pressure become?
A flexible container at an initial volume of 3.10 L contains 8.51 mol of gas. More gas is then added to the container until it reaches a final volume of 13.7 L. Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container.
When 2.5g of Al reacts with 5.0g of Cl2, 8.3g of AlCl3 is formed. Calculate the limiting reactants, theoretical yield, and percent yield for the reaction. 2Al + 3Cl3 ---> 2AlCl3
What is the theoretical yield in g of Ag2S produced from the reaction?
An open flask sitting in a lab refrigerator looks empty, but it is actually filled with a mixture of gases called air. If the flask volume is 1.00 L, and the air is at standard temperature and pressure, how many gaseous molecules does the flask contain?
A sample of oxygen gas was collected via water displacement. Since the oxygen was collected via water displacement, the sample is saturated with water vapor. If the total pressure of the mixture at 26.4
26.4 °C is 741
741 torr, what is the partial pressure of oxygen? The vapor pressure of water at 26.4
26.4 °C is 25.81
25.81 mm Hg.
When the reaction occurred, the amount of Ag-S obtained was 45.0g. What is the percent yield of the reaction
What is the amount in g of the excess reactant expected to remain after the reaction?
