Concentrated nitric acid is a strong oxidizing agent. It is used for oxidizing most metals. The products of oxidation depend on the concentration of t...
Ammonia is prepared on a large-scale by the Haber's process. N2(g) + 3H2(g) → 2NH3(g)
Nitrogen is highly electronegative as compared to phosphorus. This causes a greater attraction of electrons towards nitrogen in NH3 than towards phosp...
General trends in chemical properties of group -15 (i) Reactivity towards hydrogen: The elements of group 15 react with hydrogen to form hydrides o...
Nitrogen is chemically less reactive. This is because of the high stability of its molecule, N2. In N2, the two nitrogen atoms form a triple bond. Thi...
General trends in group 15 elements (i) Electronic configuration: All the elements in group 15 have 5 valence electrons. Their general electronic c...
It is difficult to study the chemistry of radon because it is a radioactive substance having a half-life of only 3.82 days. Also, compounds of radon s...
Balanced equation XeF6 + 2H2O → XeO2F2 + 4HF
Air contains a large amount of nitrogen and the solubility of gases in liquids increases with increase in pressure. When sea divers dive deep into the...
ICl is more reactive than I2 because I-Cl bond in ICl is weaker than I-I bond in I2.
Two poisonous gases that can be prepared from chlorine gas are (i) Phosgene (COCl2) (ii) Mustard gas (ClCH2CH2SCH2CH2Cl)
When chlorine reacts with water, it produces nascent oxygen. This nascent oxygen then combines with the coloured substances present in the organic mat...
Sea water contains chlorides, bromides, and iodides of Na, K, Mg, and Ca. However, it primarily contains NaCl. The deposits of dried up sea beds conta...
Anomalous behaviour of fluorine (i) It forms only one oxoacid as compared to other halogens that form a number of oxoacids. (ii) Ionisation enth...
Fluorine is a much stronger oxidizing agent than chlorine. The oxidizing power depends on three factors. 1. Bond dissociation energy 2. Electron...
H2SO4(aq) + H2O → H3O+ + HSO4- ; Ka1 > 10 HSO4- + H2O(l) → H3O+ + SO4- ; Ka2 = 1.2 x 10-2 It can be noticed that Ka1 >> Ka2 This is bec...
Correct answer: (3) X = Ammonium salts, Y = SO2 Explanation: Oxides of nitrogen and sulphur are acidic and settle down on ground as dry deposition...
