Uracil is one of the Four nuleotide monomers that make up the nucleic acid RNA. uracil acid and has a molar
mass of 112g/mol. A biologist prepares a solution of the
acid by dissolving 1.24g of the compound in 1.0L of solution. The pH of the Solutionis 5.71. Calculate the
acid-dissociation Constant ka for uracil. what percent of its molecule were dissociated in the solution

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).

One does not belong why? ice, gold ,wood ,diamond and table salt
