When elemental carbon is burned in the open atmosphere, with plenty of oxygen gas present, the product is carbon dioxide.
C(s) + O2(g)--> CO2(g)
However, when the amount of oxygen present during the burning of the carbon is restricted, carbon monoxide is more likely to result.
2 C(s) + O2(g)--> 2 CO(g)
What mass of each product is expected when a 4.50 g sample of pure carbon is burned under each of these conditions?
What is the numerical value of the rate constant and what are the units? D) Calculate the rate of this reaction when the initial concentrations of OCl- and I- are 7.6 x10-3 M and 9.6 x 10-3M respectively.
Determining Copper in Brass, 1st I titrated Na2S2O3 and determined the molarity to be 0.164. I am having trouble with the calculations for the dissolution of brass.
How does this affect the reported solubility product of borax at that temperature? Explain. Temperatures can range from 4.4 degrees C, 17.1 degrees C, 34.6 degrees C, 41.6 degrees C, and 50.6 degrees C.
What volume of O2 at 684mmHg and 37degree celsius is required to synthesize 22.0 mole of NO2.
Using the moles of air, temperature of air and slope of the Air Volume vs. 1/pressure graph, calculate the ideal gas constant.
What is the molar mass of the unknown acid? B) As the acid is titrated, the pH of the solution after the addition of 15.00mL of the base is 9.46. What is the Ka for the acid?
What is the smallest possible integer coefficient of S in the combined balanced equation and compute the final pressure in the tank if nothing else is altered in the surroundings.
Mount Whitney in California is the highest point in the lower 48 states and is within 150 miles of the lowest place in North America. The normal pressure at the summit is 440mm Hg.
Indicators can be used to estimate the pH value of soultions. To determine the pH of a 0.01M weak acid (HX), a few drops of three different indicators are added to separate portions of HX. The resulting colors of the HX solution are below.
A piece of metal of mass 27 g at 99?C is placed in a calorimeter containing 45.1 g of water at 21?C. The final temperature of the mixture is 38.7?C.
What characteristic absorption bands would you expect to find in the infrared spectrum of caffeine?
