The following and use the results in the data sheet provided
a) What is the theoretical yield of bismuth when 276 g of Bi2O3 reacts with excess carbon as shown below?Bi2O3 + C(s) => Bi(s) + CO(g) (not balanced)
b) solved
c) Potassium reacts with oxygen to make potassium oxide, K2O. What is the maximum mass (g) of K2O(s) that could be prepared from 8.18 g of K(s) and 2.72 g of O2(g)?
Carbon monoxide and water vapor, each at 190 Torr, were introduced into a 250 mL container. When the mixture reached equilibrium at 690 ?C, the partial pressure of CO2(g) was 108 Torr.
The values of delta h and delta s for the reaction CaCo3(s) yields CaO(s)+CO2(g) are 177.8kJ and 160.5 J/K respectively. the pressure of CO2 at equilibrium for the process
Predict the products when cyclohexanol is heated in the presence of H+. Show both the organic product and the byproduct
Calculate the pH in the titration of 25.0 mL of 0.100 acetic acid by sodium hydroxide after the addition
When doing a recrystallization, why is it important to allow the saturated solution to boil for ~1 minute and cool SLOWLY to room temperature before placing it in an ice-water bath?
What is the theoretical percent, by weight, of calcium in Ca(OCl)2
At a certain temperature and pressure 4.2 L of N2 reacts with 6.3 L of O2. If all the N2 and O2 are consumed, what volume of N2O3, at the same temperature and pressure, will be produced?
the recrystallization is slow typically the flask is closed with a cork. What do you think is the reason for using a cork and not a plastic stopper (which would seal the flask better)
The normal boiling point of ethanol (C2H5OH) is 78.3 °C and its molar enthalpy of vaporization is 38.56 kJ/mol. What is the change in entropy in the system in J/K when 62.2 grams of ethanol
