Research and write about the history of Haber Process of producing ammonia. How did it address the Malthusian Threat? What was the Haber-Nernst Controversy (be sure to use Le Chatelier's Principle in the explanation)? How did Bosch ultimately come up with the solution?
Given the following data table of average bond enthalpies, estimate the ΔH^rxn for the reactions 2H2+O2-- 2H2O. What is the hybridization of xenon in each of your Lewis resonance structures?
transferred from an oven (183°C) to 189 g of water at 23.2°C, into which it is immersed. The water and steel together reach a temperature of 27.9°C. What is the mass of the steel in grams
A 1-L flask is filled with 1.10 g of argon at 25 C. A sample of ethane vapor is added to the same flask until the total pressure is 1.20 atm . What is the partial pressure of argon,PAr , in the flask?
Calculating percent purity from a reaction, One of the reactions that occurs in a blast furnace, where iron ore is converted to cast iron is Fe2O3 + CO = Fe + CO2.
Write the formula of all the different carbon dioxide molecules that can be formed from these samples. Which molecule has the largest mass?
An unknown compound contains only carbon, hydrogen, and oxygen. Combustion of 4.00 g of this compound produced 5.87 g of carbon dioxide and 2.40 g of water.
calculate the initial reaction rate when [O3] & [NO] remain essentially constant at the values [O3]0= 7.48 x 10-6 M & [NO]0= 3.26 x 10-5M, owing to continuous production from separate sources.
