Given the following equation. What is the maximum mass of FeO3 that can be prepared when 360.0g of FeS2 are mixed with 47.5g of oxygen gas?A balanced equation is this: 4 FeS2 (s) + 11 O2 (g) ----> 2 Fe2O3 (s) + 8 SO2 (g)
The bottom liquid is a relatively heavy lubricating oil, and the top liquid is water. Of the total block volume, 54.2% is immersed in the oil and the balance is in the water. In a separate experiment, an empty flask is weighed, 35.3 cm cubed of th..
Calculate the relative amounts of 1-chloropropane and 2-chloropropane obtained by the radical chlorination of propane, using this relative rate of reactivity.
When a 2.00-g sample of KSCN is dissolved in water in a calorimeter that has a total heat capacity of 1.083 kJ·K-1, the temperature decreases by 0.460 K.
2-methyl-2-butanol reacts with HBr to form 2-bromo-2-methyl butane and water while butanol reacts with HBr to form 1-bromobutane and water. Give a detailed explanation as to why the 2-methyl-2-butanol forms a carbocation in the mechanism while but..
Electron affinity can be defined for molecules just as it is defined for single atoms. Write a complete chemical equation representing the electron affinity of OH. Include all relevant state symbols.
phosphoric acids, rather than hydrochloric acid, used to catalyze the dehydration of alcohols?
Draw the condensation reaction that would form the dipeptide Met-Ile from the amino acids, Methionine and Isoleucine. Based on the characteristics of the side chains ONLY, would you expect the dipeptide to be polar or nonpolar
A sample of commercial sulfiruc acid is 96.4% H2SO4 by mass, and its density is 1.84 g/ml. Calculate the molarity of the sulfuric acid solution.
The inlet velocity to and the outlet velocity from the scrubber are 25 ft/s and 20 ft/s, respectively. The scrubber cools the flue gas to 5500F. Determine the duct size required at the outlet of the unit.
We do not have any gardening books, magazines, or access to the Internet (horrors!). We need to observe a number of characteristics for these plants. What are some of the characteristics that we want to observe. What might be your initial hypothes..
