The relative pKa values depend on the substituent. The ortho isomer is the most acidic, and the para isomer is the least acidic. Explain these relative acidities. 107PRACTICE PROBLEM Examine the compounds below with their pKa values. Show the conjugate base of each compound and rationalize why...
X(s) and X2O3 (s) is allowed to react with 6M HCl(aq) . 0.0954dm3 of the acid is needed for both the metal and its oxide to undergo complete reaction.Based on this information , Deduce respectively the greatest value and the smallest possible value of the relative atomic mass of X...
9. James Chadwick added the finishing touch to the Atomic Theory.What sub-atomic particle did Chadwick discover?What is the charge on this particle and where is it located in the atom? ** The Rutherford-Bohr model of the atom is still not entirely correct.Currently, the“Quantum-Mechanical ...
The pattern of bars is called mass spectrum and each bar corresponds to a particular mass.The bar produced by the heaviest ion (the one with the highest mass/charge)gives the relative formula/molecular mass of the compound.(i)Suggest the name of the sub-atomic particle that must be lost ...
1. A beam of neutrons of constant velocity, mass M. (M. 1.67 x 10 * kg) and energy E, is incident on a linear chain of atomic nuclei, arranged in a regular fashion as shown in the figure... A ski jumper starts from rest from point A at the top of a hill that is a height...
and planets revolved around the Earth. This view was supported by observations that appeared to show the Sun and other celestial objects moving across the sky relative to the Earth. It wasn't until the heliocentric model was proposed by Nicolaus Copernicus in the 16th century that the Earth's...
Anions are generated when an atom obtains one or more electrons, resulting in an excess of negatively charged electrons in the nucleus relative to protons that are charged positively. Discuss this question10. Atoms with the same number of neutrons but a different number of protons are called __...

The relative age of planetary surfaces is often defined by the abundance of impact craters, as these form at a more-or-less uniform rate. With the notable exception of regions on Enceladus, the surfaces of the Saturnian satellites were revealed by Voyager imaging to be heavily cratered, and...
Isomerism is when two or more polymer molecules or repeat units have the same composition, but different atomic arrangements.Concept Check 4.2Question: On the basis of the structures presented in the previous section, sketch the repeat unit structure for poly(vinyl fluoride).Answer: Inasmuch as ...
