In the following reaction, C2H5OH + 3O2 → 2CO2 + 3H2O, if 54 grams of water is produced, how many grams of C2H5OH is needed for the reaction.
When the equation above is balanced and all coefficients are reduced to their lowest whole-number terms, the coefficient for O2
if 500g of potassium chlorate solid decomposes and produces 303g of potassium chloride solid, how many grams of oxygen gas are produced?
The vapor pressure of water is 28.3 torr at 29°C then determine what is the partial pressure of oxygen collected if a reaction at that temperature produces Carbon Dioxide which is collected over water at a total pressure of 576 torr, ?
The solute increases the volume of the solution, and an increase in volume requires an increase in the temperature to reach the boiling point (derived from PV = nRT).
Using the average bond dissociation enthalpies(BE) given, estimate the standard molar heat of reaction of the gas-phase reaction of hydrogen peroxide with methanol to yield formaldehyde and water:
Because of increasing evidence of damage to the ozone layer, chlorofluorocarbon (CFC) production was banned in 1996. However, there are about 100 million auto air conditioners
How many moles of oxygen are consumed in burning 1.60 moles of benzene, C6H6?
You have 1005.3 g of a bleach solution. The percent by mass of the solute sodium hypochlorite, NaOCl, is 3.62%. How many grams of solvent are in the solution?
75.0 mL of a 1.80 M solution is diluted to a volume of 258 mL. A 129-mL portion of that solution is diluted using 187 mL of water.
Suppose 10.0 g of CH4 is used in a reaction that can theoretically produce 95.8 g of CCl4. What is the percent yield of CCl4 if the reaction produces only 80.0 g of CCl4.
Calculate the number of moles of sodium hydroxide used in the titration. b. How many equivalents of unknown acid were titrated? c. Determine the equivalent mass of the unknown acid
