Concentrated ethanol solutions can be used to kill microorganisms. At low concentrations, however, such as in some wines, the microorganisms can survive and cause oxidation of the alcohol. What is the structure of the acid formed?
The half-life for the radioactive decay of is 5730 years. How long will it take for 20% of the atoms in a sample of to decay. If a sample of initially contains 1.1 of , how many millimoles will be left after 2285 years
Using all the inorganic reactants neccessary and only CH3I and acetylene as carbon based compounds, make (2S,3R)-2,3-butanediol. Show both a retrosynthesis and forward synthesis.
A metal sample weighing 124.10 g and at a temperature of 99.3 C was placed in 42.87 g of water in a calorimeter at 23.9 C. At equilibrium the temperature of the water and metal was 41.6 C.
When 28.6 kg of Fe2O3 react with 17.2 kg of CO and 6.3 kg of Fe are recovered, what is the percent yield for the reaction?
Explain how FeBr3 assists the reaction. Br2 dissolves in a number of solvents, but we preferentially use glacial acetic acid.
Find out What mass of the NaHCO3 reacts with the vitamin C When the tablet dissolves in H2O, it "fizzes" because the reason for this is the CHO3 reacts with the citric acid(C6H8O7 a weak organic acid) and the vitamin C?
Magnesium metal is used as a sacrificial anode to reduce the corrosion of underground storage tanks (made of iron, more accurately steel). As a result the sacrifical metal corrodes instead of iron. Explain
From its electronic configuration, predict which of the first 10 elements would be most similar in chemical behavior to the as yet undiscovered element 170.
What is the maximum amount of solid NaCl will dissolve in 1 liter of a 1 M solution with a 1:1 ration of MgCl2 and CaCl2
this solution was added 1.960 grams of KI and 50.00 mL of a 0.00923 M KIO3 solution. The excess I3- was titrated with 50.00 mL of a 0.02000 M Na2S2O3 solution. What was the mass percent of arsenic trichloride in the original sample?
