A 16.4-L sample of gas at STP is heated to 55°C at 605 torr. What is the new volume?
Methyl Orange is an acid-base indicator. In dilute solution, at pH greater than 4.4, it is yellow. At pH=3.2 the solution appears red. Draw a structure of the species that is formed at the lower pH of the acid proton adds to the azo nitrogen atom ..
How can i find the pressure of oxygen if it's in a mixture of .40 moles of oxygen and .20 moles of nitrogen at 1.2 atm pressure
Determine the boiling point of an aqueous solution that is 2.30 m ethylene glycol (C2H6O2); Kb for water is 0.52 degrees celsius/m.
Titration of 15mL of 0.125M unknown base with 0.103M HCl required 18.2mL to reach the equivalence point. the pH at the equivalence point was 2.74.
A 50.0 mL sample of vinegar (density = 1.06 g/mL) was diluted to 500.0 mL. Titration of a 50.0 mL aliquot of this solution required 42.5 mL of 0.0900 M NaOH to reach the end point. Determin the acid content of the vinegar as wt. % acetic acid.
