1) Why is DNA classified as a polymer? What are the monomers? (2) What force holds together the strands of DNA? Why would covalent bonding be problematic? You must provide sufficient detail in your answer and incorporate information from the course materials to receive credit.
A study of the water-gas shift reaction given below was made in which equilibrium was reached with [CO] = [H2O] = [H2] = 0.10 M and [CO2] = 0.31 M. After 0.41 mol H2 is added to the 2.0 L container and equilibrium is reestablished

Find for the combustion of naphthalene. The heat capacity of the calorimeter, determined in separate experiment, is.
What component of air will bring about this reaction and what is its approximate concentration in air? If you had a stoppered flask with basic luminol and then opened it to the air
Choose the answer which presents the chemical formulas for two substances in order of decreasing melting point (highest melting point first) and gives a valid reason for this order.
A particular element exists in two stable isotopic forms. One isotope has a mass of 34.9689 amu ( 75.77% abundance). The other isotope has a mass of 36.9659 amu. Calculate the average mass of the element and determine its identity.
Compounds like CCl2F2 are known as CFCs and were once widely used as refrigerants. Breaking down of these molecules in the atmosphere releases Cl atoms
How many grams of argon would it take to fill a light bulb with a volume of 0.475L at STP
Which of the following compounds/ions exhibit resonance? Select "yes" or "no" for each compound
Assume that while extracting material from gallstones you have isolated a compound that you suspect is cholesterol, but you cannot be sure. How would you experimentally prove that the sample that you have isolated is actually cholesterol using mel..
consider the titration of 25.00ml of 0.650 M propanoic acid, HC3H5O2 ( Ka = 1.3 X 10^-5), with 0.750 M sodium hydroxide, NaOH, and answer the following questions?
The crossed aldol condensation of acetaldehyde with benzaldehyde is aided by the fact that benzaldehyde bears no α-protons. However, a possible competitive reaction is the “selfcondensation†of two molecules of acetaldehyde.
