Determine each of the following for a 0.500 M HBr solution. 1) Express your answer using three significant figures [H3O+]= M 2) Express your answer using three decimal places pH= 3)the balanced equation when reacted with LiOH. Express your answer as a chemical equation. Identify all of the phases in your answer 4) milliliters of HBr solution required to neutralize 40.0 mL of a 0.450 M LiOH solution. V HBr = mL
of an apparatus that could be used to electroplate a ton spoon with Ag. Label the anode and cathode, suggest an electrolyte, and write the anode and cathode half reactions. explain how the process takes place.
What is the pH at the half-stoichiometric point (half-way to the endpoint) for the titration of 0.22 M HNO2(aq) with 0.10 M KOH(aq)?
The reduction reaction has the product 4-tert-butylcyclohexanol which is a mixture of cis and trans isomers. Methanol is the solvent, but I don't think that goes into the balanced equation.
A mixture of camphor and water boils at approximately 99.1?C. At this temperature the vapour pressure of water is 736 mmHg. Calculate the percentage of camphor and water in the steam distillate by number of moles.
An industrial wastewater contains 2000 mg/L of total Ammonia as N, 490 mg/L of total Ni and has no inorganic carbon. The PH = 2.8. Using the diagram calculate to what pH the waste must be adjusted to so that the total Ni concentration is 1 mg/L.
A person ate 0.999 pound of cheese (an energy intake of 7990 kJ). Suppose that none of the energy was stored in his body. What mass (in grams) of water would he need to perspire in order to maintain his original temperature? (It takes 44.0 kJ to v..
A gas cylinder that contains argon has an internal volume of 6.88 L. A pressure gauge attached to the cylinder reads 1870 psi (1 atm = 14.7psi) at 20.0C.
A 64 L sample of dry air is cooled from 137°C to -20.°C while the pressure is maintained at 2.85 atm. What is the final volume
Design a series of reactions to convert ethanol to 2-butanol. You can use other inorganic reagents you need
A hydrogen atom is removed from the first carbon atom of a butane molecule and is replaced by a hydroxyl group. Draw the new molecule formed.
a sample of neon to escape from a hole in a container, how long would it take for an equal amount of nitrogen gas, N2, to escape
A student during an extraction experiment lost track of whether a beaker contained an aqueous solution or an organic solution. How could the student determine which type of solutions was in the beaker by a simple test
