How can the NaCl be removed from the copper oxide? Add aqueous Ag NO₃ to the mixturePlace the mixture in a separating funnel Heat the mixture and allow it to cool Add water to the mixture and filter Question 4 of 17Question 5 of 17 5. The results of the accurate weighing of some crystals are as follows: Mass of weighing bottle empty = 25.652 gm Mass of weighing bottle + crystals = 26.541 gm What is the mass of the crystals? 1.889 gm 1.111 gm 0.111 gm 0.889 gm Question 5 of 17Question 6 of 17 6. NaF and MgO have both atomic ration 1:1 in their crystals such property is Isotropy Allotropy Isomorphism Polymorphism Question 6 of 17Question 7 of 17 7. The temperature at which two or more than two types of crystals exist in equilibrium is called. Transition temperature Melting Point Eutectic temperature Boiling pointQuestion 7 of 17Question 8 of 17 8. Iron acts as an electrical conductor due to Electron cloud Free protons Free ions Free neutrons Question 8 of 17Question 9 of 17 9. Crystal Lattice is an arrangement of particles in Three dimensions Two dimensions One dimension Four dimensions Question 9 of 17Question 10 of 17 10. The solids in which atoms, ions or molecules have random non-repetitive three dimensional arrangements are termed as: Alloys Glasses Amalgams Crystals Question 10 of 17Question 11 of 17 11. Electric current can pass through graphite in one direction but not through other direction of crystal such a property is called Anisotropy Isomorphism Allotropy Polymorphism Question 11 of 17Question 12 of 17 12. Lead and zinc can be separated by distillation because they have different. Boiling point Densities Reactivities Mass numbers Question 12 of 17Question 13 of 17 13. Lattice energy is also called Bond Energy Energy of affinity Crystal energy Ionization energy Question 13 of 17Question 14 of 17 14. When gaseous ions are allowed to form a crystal, energy Has no effect Is sometimes absorbed and sometimes released Is evolved Is absorbed Question 14 of 17Question 15 of 17 15. A crystal of the purple compound Potassium Permanganate placed at the bottom of a beaker of water and the beaker left until there is no further change. What will be observed? A colourless liquid with the purple crystal unchanged A colourless layer below a purple layerA Purple layer below a colourless layer A uniformly purple solution Question 15 of 17Question 16 of 17 16. Which of the following method is most suitable for obtaining a pure, dry sample of NaCl from a mixture of NaCl and sand? Shake the mixture with water. Filter and dry the substances on the filter paper. Shake the mixture with water. Filter and evaporate the filtrate. Shake the mixture with water and distil off the sand Heat the mixture gently and collect the substances which boil off Question 16 of 17Question 17 of 17 17.
