Describe how collecting pressure and temperature data in a sealed rigid container could be used to determine absolute zero
Solid lead (I) sulfide reacts with aqueous hydrochloric acid to form solid lead (II) chloride and dihydrogen sulfide gas.
A solution contains a mixture of Cl- and Br- ions. Can both be positively identified? Briefly explain. Write appropriate equations to support your answer.
In the NMR Spectra there is : 2 quartet( one has 2 hydrogens and the other has 3 hydrogens they are both located in the range 7.5-6.5) and there are two triplets at 4.5-3.5 and they both have two hydrogens, and there is a singlet located at 2.0 th..
