3. Indicate whether the following statements are true or false. What is ductility? Question 9. Prev Question Next Question. (d) carbon, Question 10. Explain the term ‘malleability’ with suitable examples. Generally, non-metals do not react with bases. It can be drawn into wires thinner that a hair or beaten into thin sheets. Which non-metal does conduct heat and electricity? The apparatus used ...” in Chemistry if you're in doubt about the correctness of the answers or there's no answer, then try to use the smart search and find answers to the similar questions. Classify the following into metals and non-metals: Non-metal like iodine is used in the purple coloured solution applied on wounds. State whether the following statements are true or false? When rocks exhibit ductile behaviour, their mineral grains tend to flatten and elongate when subjected to differential stress. Question 23. Answer: 1. good conductors, electricity (c) Generally, metals are ductile. 6. True False Correct : A compound is made up of two or more elements is a fixed proportion by mass. 5. CBSE Solutions CBSE Previous Year Question Paper With 14. (a) hydrogen gas (b) non-sonorous (3) False. Answer: What are non-metals? Copper is used in wiring because it is both ductile and conductive. Ductility is one of the properties of metals due to which they can be drawn into wires. 2. Write True Or False : When Iron and Sulphur Are Heated Together a Grey Mass is … (d) None of these, Question 12. Lead is used in making electrodes and batteries. Metals tend to be ductile, malleable, have a metallic luster and are conductors of heat and electricity. 6. acidic The only liquid metal is _____. Answer: (c) (c) 3. For example, a brittle material can behave like a ductile one at an elevated temperature. Sulphur forms _____ oxides. Is it true or false? Pure substances and mixtures. (c) Lithium Answer: But at room temperature, it hardens. Malleability and sonority. Ductile to brittle transition is about how small changes in ambient temperature can make a big difference in terms of mechanical performance. 7. (d) 15. (a) Nitrogen Wir und unsere Partner nutzen Cookies und ähnliche Technik, um Daten auf Ihrem Gerät zu speichern und/oder darauf zuzugreifen, für folgende Zwecke: um personalisierte Werbung und Inhalte zu zeigen, zur Messung von Anzeigen und Inhalten, um mehr über die Zielgruppe zu erfahren sowie für die Entwicklung von Produkten. True or False 5. (c) Iron The card should have information like name of metal/non-metal; its physical properties, chemical properties and its uses. Answer: (5) True. (b) Pick up wrong statement about wrought iron (a) It contains carbon of the order of 0 to 0.25% (b) It melts at 1535 C (c) It is very View Answer. (d) Aluminium, Question 11. (c) Copper displaces zinc from zinc sulphate solution. So this Sulfur is a natural element and exists in many forms. Cast Irons Miguel Angel Yescas-Gonzalez and H. K. D. H. Bhadeshia Cast irons typically contain 2-4 wt% of carbon with a high silicon concentrations and a greater concentration of impurities than steels. This is because iron filings are attracted to the magnet but sulfur is not. C. The 1st statement is false while the 2nd statement is true. Gold and Silver _____ react with dilute acids. For example, when zinc (Zn) reacts with copper sulphate (CuS04), zinc replaces copper being it more reactive than copper. No, because copper is less reactive than zinc and will not be able to displace zinc from its salt solution. It may be solid, liquid, or gas. (d) none of these, Question 19. Advertisement. Whose oxides are basic in nature: Metal or non-metal? In case one principal stress is zero, the other principal stress is equal to: Maximum shear stress. Why or why not? Question 1. 4. Distinguish between metals and non-metals on the basis of their chemical properties. Metalloids possess the properties of That is why it is prepared for making jewellery.
