determine K for this reaction When a sample of 5.63 grams of pure C 5 H 6 O 3 (g) was sealed into an otherwise empty flask of 2.50 L and heated to 200.
Transition metals can combine with carbon monoxide to form compounds such as Fe(CO)5 and Co2(CO)8. If you combine 0.150 g Ni with CO and isolate 0.437 g Ni(CO)x
If the sign for delta G is negative (spontaneous process) and the sign for delta S is positive (more disorder) for both dissolving processes, how could one be endothermic (positive delta H) and one be exothermic
how many liters of o2 can be made from 342g H2o2 if the density of o2 is 1.428g.
A 4.78g sample of aluminum completely reacts with oxygen to form 6.67g of aluminum oxide. What is the mass percent composition of aluminum in aluminum oxide?
What happens to the solubility of an ionic compound as ionic strength of the solution increases up to ~0.5 M)? Why is there a correlation between the solubility of an ionic compound and the ionic strength of the solution?
What are the molar enthalpy and total enthalpy of the pure system when 50% and 75% have been evaporated at: (i) 30°C, (ii) 50°C? Use liquid at 25°C as a reference state
What is the final temperature (in °C) of 1.53 g of water with an initial temperature of 12.0°C after 7.478 J of heat is added to it?
An iron ore sample is a mixture of Fe2O3 and several impurities. A 752. g sample of the impure iron ore is heated with excess carbon. Only the Fe2O3 present in the ore reacts with the carbon producing 341. g of carbon monoxide by the following rea..
