A small smelter converts galena

1. A small smelter converts galena (lead sulfide) into pure lead by heating the ore with an excess of oxygen. Sulfur dioxide is produced as an air pollutant as a result of the reaction. To remove sulfur dioxide, the flue gas is passed through a slurry of lime (calcium oxide) to produce calcium sulfate. The smelter processes 1 ...continues

This deals with limiting reactants in stoichiometry

If 45.7 grams of Na reacts with excess H2O, how many grams of each product will form? (You need to determine the equation of the reaction in order to determine the answer). I am working as a substitute teacher and need to teach this material to my class - please explain the steps needed to solve this question (at the high sc ...continues

Stoichiometry problem dealing with limiting reagents

If 275.0 mL of 0.5000 M ZnCl2 reacts with 1.650 x 10 to 23rd power of AlPO4 compounds in the following reaction, what is the limiting reagent, how many moles of excess reagent will there be, and how many grams of each product will form? 3 ZnCl2 + 2 AlPO4 yields Zn3(PO4)2 + 2 AlCl3 I am substitute teaching, and I would lik ...continues

This deals with limiting reactants in stoichiometry

If 350.0 mL of 6.00 M H2SO4 reacts with 45.00 grams of Al in the following reaction, what is the limiting reagent, how many moles of excess reagent will there be, and how many liters of H2 will form? The reaction is: H2SO4 + Al produces Al2(SO4)3 + H2 If you could please show the steps, I'd appreciate it.

This deals with limiting reactants in stoichiometry and percent yield.

Use the following equation: H2SO4 + Al produces Al2(SO4)3 + H2 Given this information: 350.00 mL of 6.00 M H2SO4 reacts with 10.00 grams of Al. This collects 13.55 L of H2. What is the percent yield of the reaction? Could you please show the steps taken to solve the problem? Thank you.

This is a stoichiometry problem.

If 7.85 x 10 to the 24th power Sc atoms react with excess CaO, how many grams of each product will form? You will need to determine the equation of the reaction. Please show steps to solve the problem. Thank you.

This deals with calorimeter and heat capacity.

If 2.500 g of Mg is burned in a constant volume calorimeter with a heat capacity of 1.10 kJ/degrees Celsius containing 1.500 L of water at 23.50 degrees Celsius and releases 37.33 kJ of heat, what is the final temperature of the calorimeter and water? Please show work and solve. Thank you.
