If an 20 mL acetic acid is neutralized with 50 mL of 0.8 M NaOH, what is the concentration of the acid?
Many gases are shipped in high-pressure containers. Consider a steel tank whose volume is 65.0L and which contains O2 gas at a pressure of 16,500kPa at 23°C.
A "little more" than 5 mL of a saturated solution of borax is transferred to the corresponding calibrated test tube and subsequently titrated with the standardized hydrochloric acid solution.
A gas in a sealed container has a pressure of 125 kPa at a tempurature of 30.0 degrees celcius. If the pressure in the container is increased to 201 k Pa, what is the new tempurature?
The concentration of Mg2+ in seawater is 0.052 M. At what pH will 86% of the Mg2+ be precipitated as the hydroxide salt? [Ksp for Mg(OH)2 = 8.9 10-12.]
Chemistry - Other explained in this solution, If world energy consumption continues to rise at the present rate of 2.4%, how long will it take to double (expressed in years)?
Neon crystalizes in a face-centered cubic lattice. It's density is 1.45 g/cm3. What is the edge length of the unit cell? Note: The atomic weight of Ne is 20.2 g/mol, and Na is 6.02 x 10^23/mol
A student takes a mixture of sugar (C6H12O6), diamond powder (C) and BaCO3, separates the mixtures and recovers 1.75g sugar, 0.86g diamond powder and 2.29g BaCO3(s). Student % recovery was 96.46%, less than the initial amount of mixture they start..
