Iron(III) oxide reacts with carbon monoxide to produce iron and carbon dioxide.
Fe2O3(s) + 3 CO(g) --> 2Fe(s) + 3 CO2(g)
What is the percent yield for the reaction if 65.0 g of iron(III) oxide produces 15.0 g of iron?
What is the percent yield for the reaction if 75.0 g of carbon monoxide produces 85.0 g of carbon dioxide?
Determine the percent yield(with respect to CO2 and CH4) of the reaction if 1.25g of CO2 was formed by reacting 2.50g of CH4(g) with excess O2 in the reaction: CH4(G) +O2(g) ---->CO2(g) +H2O(g).
Is a first order rate constant of 3.14x10^-4 1/s at room temperature, if you currently have a 2.5 M N2O5 how long will it take for 65% of N2O react?
Problem- 1) Calculate the resolution for a 1115.5 keV Zn peak that has a FWHM of 2.01 keV. 2) Calculate the resolution for a 1115.5 keV Zn peak that has a FWHM of 200 keV.
Ethanol (CH3Ch2OH) the intoxicant in alcoholic beverages, is also used to make other organic compounds. In concentrated sulfuric acid, ethanol forms diethyl ether and water.
The activation energy for the following first-order reaction is 318 kJ/mol. N2O5(g)-->2NO2(g)+(1/2) O2(g). The value of the rate constant (k) is 6.65x10^-5 s^-1 at 84 degrees C. What is the value of k at 49 degrees C. (R=8.314 J/mol K)?
