CIE Inorganic chemistry Quizz 1 Welcome to your CIE Inorganic chemistry Quizz 1 Which of the following is not true about ionization energies of an element? Difference between successive ionization energies of an element is uniform It is defined for gaseous atoms It is affected by distance of electron from nucleus It decreases down a group Which of the following correctly puts the elements in order of increasing first ionization energy? Na, Al, Mg Na, Mg, Al Al, Mg, Na Mg, Al, Na Oxide of which element(s) have giant macromolecular structure?I. SiliconII. PhosphorousIII. Sulphur I only I and II only I and III only II and III only Which of the following statement about period 3 is not true as we move from left to right? Atomic radius increases 1st ionization energy increases Element change from metals to non metals Electronegativity increases Which of the following is incorrect about magnesium? Magnesium reacts with steam to produce magnesium hydroxide Magnesium has shorter atomic radius than calcium Magnesium hydroxide is less soluble in water compared to barium hydroxide Magnesium has higher melting point than barium Which of the following is correct about barium? Barium Hydroxide is soluble in water Barium is less reactive than calcium Barium sulpahte is more soluble in water than magnesium sulphate All the options are correct Which of the following lists elements in order of increasing reactivity? Mg, Ca, Sr, Ba Ba, Sr, Ca, Mg Mg, Ba, Sr, Ca Ca, Ba, Sr, Mg Which of the following is true about group 2 nitrates? The temperature at which thermal decomposition of nitrates takes place increases down the group. Stability of nitrates decreases down the group. Thermal decomposition of nitrates releases carbon dioxide gas Nitrates of group 2 elements are easily polarised when the cation is larger in size For which of the following salts of group 2 elements, the solubility decreases down the group?i. Sulphatesii. Nitratesiii. Hydroxides i only ii and iii only ii only i, ii and iii Which of the following reacts with potassium bromide to give a yellow solution? Aqueous chlorine Aqueous Fluorine Aquesous Iodine Aquesous Silver nitrate What is the reaction called in which chlorine reacts with sodium hydroxide to form sodium chlorate (I)? Disproportionation Oxidation Reduction Displacement Which halide ion gives a pale yellow precipitate with silver nitrate? Iodide ion Fluoride ion Chloride ion Bromide ion Which of the following can cause colour change in compounds of a transient element?I. LigandII. Coordination numberIII. Oxidation state I, II, and III I and II only III only I only Which of the following statements about oxidation state of transition elements is not correct? Compounds with high oxidation states are often reducing agents Chromium has two main oxidation states Manganese has the highest number of possible oxidation states its period Vanadium has four main oxidation states Which of the following is used as a catalyst in Haber process? Iron Vanadium(v)oxide copper silver Transition metals can act as homogeneous catalysts because they can form various oxidation states compounds isotopes colors Addition of concentrated HCl to aqueous ions of Cu leads to a change in coordination number from 6-4 4-6 4-8 8-4 Time is Up!
