What is the difference between Acidic oxides and Basic oxides?
Oxides are compounds having at least one oxygen atom bonded to another element. If an oxide reacts with a base but not with acids, it is an acidic oxide. The key difference between acidic and basic oxides is that acid oxides form...

while is second ionization energy of alkaline earth metals is less than that of corresponding alkali metals
Although IE1 (first ionization energy) values of alkaline earth metals are higher than that of alkali metals, the IE2 (second ionization energy) values of alkaline earth metals are much smaller...

WHICH ABSORBS THE NITROGEN FROM OXIDES OF NITROGEN OR ABSORBS TOTALLY OXIDES OF NITROGEN IN EASY WAY
Any surface is to some extent able to absorb gases. Thus, a small amount of nitrogen oxides will settle on any of your sorbent at any temperature. But in order...

1. an aqueous solution has a pH equal to 2.what do you infer about its acidic and basic character?
2.what is the colour of methylorange i.acidic mediumii.basic medium
1) It is a very low value of pH. As we know, low pH (<7) is observed in acidic conditions, while high pH (>7) is related with basic conditions. So...

What are alkali metals? Why do these metals not occur in free state in nature? List the principal ores of alkali metals.
Alkali metals are: - Lithium (Li); - Sodium (Na); - Potassium (K); - Rubidium (Rb); - Cesium (Cs); - Francium (Fr). All alkali metals have their outmost electron in the s-orbital. This pre-determines their high chemical...

Question #3
The n to pi star in acetone occur at longer wavelength than the pi to pi star transition, yet the latter transition has a much higher molar absorptivity. Explain.
This is because the lone pair interacts with the solvent such that the solvent align itself with ground state thus lowering energy at ground state and not at excited state.
