Expalin how you would prepare 500.0mL of a solution that is 0.100 M of H2SO4 from concentrated 18.0 M of H2SO4, which is a liquid with density 1.82g/mL?
In 1774, Joseph Priestley discovered that mercury(II) oxide decomposes on heating to elemental mercury and a gas, later called oxygen. If 56.0 g of mercury(II) oxide is heated and 26.0 % of it decomposes,

An aqueous NaCl solutions is made using 112 g of NaCl diluted to a total solution volume of 1.0 L. Calculate the molarity, molality and mass percent of the solution
Reaction kinetics - Determination of the activation energy of the reaction between oxalic acid and potassium permanganate.
At pH 12, magnesium hydroxide is insoluble and does not react with EDTA. The titration of a hard water sample at pH 12 thus yields results for calcium only. A 250.0-mL sample of tap water was adjusted to pH 12 and titrated with 0.01056 EDTA using ..
A compound A has prominent infrared absorptions at 1050, 1786, and 1852 cm-1 and shows a single absorption in the proton NMR spectrum at ? 3.00. When heated gently with methanol, compound B, C5H8O4, is obtained.
