A pure titanium cube has an edge length of 2.65 .How many titanium atoms does it contain? Titanium has a density of 4.50g/cm^3
we need to form a cyclohexanone with a methyl group at the 6 position and a 2,3-butanediol group (with both OH groups at the back (dashed lines)) at the 2 position. All carbons on the target need to come from the starting materials, but other than..
A student dissolved 0.1319g of an unknown diprotic acid in 100mL of distilled water. The acid was then titrated with 0.1005M NaOH solution. The second equivalence point showed the sharpest change in pH, and so it was used to determine the molecula..
A mixture of 0.10 mol of NO, 0.050 mol of H2, and 0.10 mol of H2O is placed in a 1.0- L vessel at 300 K . The following equilibrium is established:
To what final volume should you dilute 60.0mL of a 5.40M KI solution so that 40.0mL of the diluted solution contains 3.75g of KI
Water has a considerably higher boiling point and lower vapor pressure than other molecules of similar or larger molar mass. For example, dinitrogen (N2), methane (CH4), etc.
Methyl salicylate is an ester and can be prepared from salicylic acid and methyl alcohol by the same method
The volume of a sample of ideal gas at 25 degrees celius is 372 mL. what will be the volume of the gas if it is heated at constant pressure to 50 degrees celius? what will the volume fo the gas be if it is cooled to -272 degrees celius.
What is the kinetic energy of the emitted electrons when cesium is exposed to UV rays of frequency \rm 1.0\times10^{15}Hz
The pH of an acid solution is 5.14. Calculate the Ka for the monoprotic acid. The initial acid concentration is 0.010M.
Bonding in some solids does not fit neatly into one of the four categories. Explain why the bonding in Na2CO3 is not purely ionic.
A solution to replace potassium loss contains 40.mEq/L each of K+ and Cl-. How many moles each of K+ and Cl- are in 1.5L solution
All numerical answers must be reported to the correct number of significant figures. What volume of 1.000 M LiCl must be diluted with water to prepare 250.0 mL of 0.100 M LiCl
