Dimethyl ether and ethanol are structural isomers of C2H6O. Which one will have a higher boiling point? Explain why and do the same for their melting points.
give the products (if any) expected from the treatment of each of the following compounds with ozone followed by dimethyl sulfide
Predict the products when 1-propanol is heated in the presence of an acid. please include a picture of it. Really appreciate it.
The heated iron metal is poured in to a calorimeter with 100 ml of water at room temperature and the calorimeter is closed. The recorded temperature of the calorimeter is 28 degrees C.
When 0.455g of Thyroxine is dissolved in 10.0g of benzene, the freezing point of the solution is depressed by 0.3000C. What is the molar mass of Thyroxine?
Determine the moles of benzene that would be needed to completely react with 0.445 moles of oxygen
Pick any two normalized eigenfunctions of the particle in the box Hamiltonian. Show by direct integration that these functions are orthogonal functions.
What is the molarity of a solution made by dissolving 2.355g of sulfuric acid in water and diluting to a final volume of 50.0 mL
A lead fishing weight with a mass of 68 g absorbs 146 cal of heat. If its initial temperature is 56°C, what is its final temperature.
The Wittig reaction involves coupling between a phosphonium ylide and a carbonyl-containing molecule. If a chemist wants to use the Wittig reaction to synthesize 3-methyl-3-hexene, which reactants should be used
Write the formula of the reactants and products-including the symbols for the state- (s), (l), (g), (aq)- then balance the equation.
Consider the dissolving of lead iodide: PbI2 (s) ?? Pb2+ (aq) + 2 I- (aq) The solubility of lead iodide (like many salts) increases at higher temperatures: At 20°C, the molar solubility is 1.45 × 10-3M
The pH of the resulting solution is 6.35. Calculate the Ka for the acid.
