Many cigarette lighters contain liquid butane. Using standard enthalpies of formation, calculate the quantity of heat produced when 5.00 g of butane is completely combusted in air under standard conditions. I did the problem, but I need a second opinion.
What is the pH at the equivalence point? (Kb of NH3 = 1.8 A 20.0 mL sample of 0.20 M sodium acetate is titrated with 0.11 M HCl(aq). What is the pH after the addition of 50.0 mL HCl(aq)?
The flask was removed, was quickly cooled to condense the volatile liquid, dried and weighed. The mass of the flask and the volatile liquid is 34.743 grams
Two common substances that are used in the northern U.S. to melt snow and ice are sodium choride (rock salt) and calcium chloride. You have a bag of a substance sold as melting salt
A compound containing only C, H, and O, was extracted from the bark of the sassafras tree. the combustion of 88.5 mg produced 241 mg of CO2 and 49.2 mg of H2O. the molar mass of the compound was 162 g/mol.
aliquot of 0.0529 m H2SO4 (aq) is to be titrated with 0.0411 m NaOH (aq). What Volume (mL) of base will it take to reach the equivalence point?
A chemistry student needs to weigh out exactly 1.19 mol of Mg(HCO3)2 to perform a laboratory experiment. How many grams should he weigh out?
Zn(s) + 2AgNO3(aq) --> 2Ag(s) + Zn(NO3)2(aq) When 216 g of silver was produced, determine the mole(s) of silver nitrate would be required.
a 75.0 mL sample of potassium hydroxide, KOH, of unknown concentration is titrated with 42.5 mL of 0.575 M acetic acid. How many moles of KOH were in the sample?
The radius of a xenon atom is 1.3\times 10^-8 cm. A 100mL flask is filled with Xe at a pressure of 1.5atm and a temperature of 254K
a 93 L sample of dry air cools from 145 degrees C to -22 degrees C while the pressure is maintained at 2.85 atm. what is the final pressure?
You have standardized the NaOH solution that has a concentration of 0.05418 M. You are given a bottle of vineaga(acetic acid) with an unknown concentration.
The concentration of Mg2+ in seawater is 0.052 M. At what pH will 92% of the Mg2 be precipitated as the hydroxide salt? [Ksp for Mg(OH)2 = 8.9* 10-12.]
