Using a sample of 35.00 mL of HCl solution after titrating it with a 0.1477 M NaOH solution. it is observed that a volume of 29.15 mL of KOH was neede to complete the process of titration. Determine what is the concentration of this unknown HCl solution?
A 1.0 L buffer solution is 0.250 M LiC2H3O2 and 0.050 M HC2H3O2 . Which of the actions will destroy the buffer? (a)adding 0.050 moles of LiC2H3O2(b)adding 0.050 moles of HCl(c)adding 0.050 moles of HC2H3O2(d)adding 0.050 moles of NaOH.
Compute the number of moles - As we know many volatile substances are present in Earth's atmosphere in trace amounts.
Multiple choice questions in organic chemistry - Which of the following statements are true about the processes of melting and freezing?

Explain Cyclopentadiene reacts as a diene in the the Diels-Alder reaction a great deal faster than does 1,3 butadiene.
The mass of an Argon atom is more than that of a Helium atom. Does that mean that because of Argon has larger mass, it exerts a higher pressure on the walls of container than Helium at the same volume, molar density and temperature? Give explanati..
