identify the most basic atom for reaction with a proton. what factors are important to the stabilization of the resulting cation?
What has a higher boiling point: dimethylpropane or pent-1-ene? and why
to find the number of chiral carbons
Why are the molecules of hydrocarbons no polar?
calculate the amount of hydreogen peroxide required for the reaction with pottasium permanganate contained in200ml of 0.1m solution (acidic medium)
Define heat capacity; molar heat capacity and specific heat capacity of a substance and give relations between them.
A water sample was tested for water hardness. A 50.00 mL sample, prepared and buffered
to pH 10, required 23.55 mL of 0.0250 M EDTA. A second 50.00 mL aliquot, prepared with
NaOH, was titrated with 14.53 mL of the same EDTA solution.
a. Calculate the total hardness of the water sample, express in ppm CaCO3
b. Calculate the concentration of CaCO3 in the sample in ppm
c. Calculate the concentration of MgCO3 in the sample in ppm
