Carbon monoxide (CO) is a poisonous gas because it binds very strongly to the oxygen carrier hemoglobin in blood. A concentration of 8.00 x 102 ppm by volume of carbon monoxide is considered lethal to humans. Calculate the volume in liters occupied by carbon monoxide in a room that measures 12.67 m long, 14.87 m wide, and 16.96m high at this concentration.
The volume of HI(aq) required to reach the equivalence point : (1c) The pH at the half-neutralization point. (1d)The pH at the equivalence point.
Draw a planar structure for the following compound using dashed or solid wedges to show the stereochemistry of the substituent groups
During the late 1800's, hard rock miners replaced candles with carbide lamps for work in mine shafts. The lamps worked by dripping water onto calcium carbide that generated acetylene gas (H2C2) that was burned.
Sodium bisulfite solution is added to an experiment at the end in order to destroy the unreacted bromine. What reaction is occuring here? Is HSO3- acting as an oxidizing or reducing agent? Write a balanced equation.
ldentify whether or not the reaction would favor the reactants or produ€ts under the specified conditions, and identify whether K gets smaller or bigger
The "lead" in lead pencils is actually almost pure carbon, and the mass of a period mark made by a lead pencil is about 0.0001g How many carbon atom's are in the period?
A reaction inside a cylindrical container with a movable piston causes the volume to change from 14.0L to 21.0L while the pressure outside the container remains constant at 0.975 atm.
Draw an oxygen saturation curve for a cooperative protein that shows a p50 of 45 torr. On the same graph draw a c curve that shows a protein that is non-cooperative with p50 of 15 torr
A list of atomic masses of the elements says that the mass of Br is 80 amu. In the mass spectrum of bromobenzene, no significant signal is seen at m/z 157.
