a student produces 2.73 g of a compound. She calculates the theoretical yield as 3.40 g. What is the percent yield
Compute percent C16H34 that reacted to form CO(g) in the process. If experiment carried out at constant V, how much heat would have been released?
Consider the reaction 4 Fe(s) + 3 O2(g) → 2 Fe2O3(s). If 12.5 g of iron(III) oxide (rust) are produced from 8.74 g of iron, how much oxygen gas is needed for this reaction?
Large quantity of ammonia are burned in the presence of platinum catalyst to give nitric oxide as d first step in the preparation of nitric acid.
The molar heat capacity of silver is 25.35 J/mol * C. How much energy would it take to raise the temperature of 8.60 g of silver by 11.1 C?
Phosphorous trichloride (PCl3) is produced from the reaction of white phosphorous (P4) and chlorine: P4(s) + 6 Cl2(g) → 4 PCl3(g) . A sample of PCl3 of mass 298 g was collected from the reaction of 75.37 g of P4 with excess chlorine.
calculate how much CaCN2 is required to form 12.6 moles of ammonia? Given that the percent yield is 65.8%?
How many moles of HCL must be added to 1.50L of 1.70M KOH to obtain a pH of 2.00?
calculate the mass loss on heating 1.200 g of a NaHCO3-NaCl mixture containing 65% NaCl
You use a properly calibrated explosimeter to measure the flammable hazard inside a tank that contained toluene and may still have some residual product a. inside.
3NaHCO3 + H3C6H5O7= 3CO2 + 3H2O + Na3C6H5O7 1g of sodium bicarbonate and 1g citric acid are allowed to react. Find the limiting reagent.
Why Do I Require More CaCO3 to Raise pH than Predicted? If you can remember back to a discussion and inquiry we exchanged last week concerning the use of sodium carbonate vs. calcium carbonate
