Mg: reacts with hot water. Acid + Metal → Ionic compound + Hydrogen gas The ability of metals to be drawn into thin wires is known as Cold, dilute nitric acid reacts with copper to form _____ (hydrogen, nitrogen dioxide, nitric oxide). Gas released in the following reaction will be: This shows that sodium is … It oxidises the H 2 produced to water and itself gets reduced to any of the nitrogen oxides (N 2 O, NO, NO 2 ). You can refer to NCERT Solutions for Class 10 Science Chapter 3 Metals and Non-metals to revise the concepts in the syllabus effectively and improve your chances of securing high marks in your board exams. Reaction of aluminium with dilute hydrochloric acid: Aluminium chloride and hydrogen gas are formed. How will you test the presence of this gas? Surface area of the metal – powdered metals react faster than large lumps. Answer: Graphite (carbon) is an example of a non-metal that conducts electricity. The metal X also reacts with sodium. Some metals reacts with dilute Nitric acid (HNO 3) and produces salt and any of the nitrogen oxides (N 2 O, NO, NO 2) and water. Answer (c) sodium Sodium reacts violently with cold water because it is high in the reactivity series. Metals and Non-metals Class 10 MCQs Questions with Answers. Reason- HNO3 is strong oxidizing agent & oxidized H2 to water. 2Al + 6HCl ⇨ 2AlCl 3 + 3H 2. 14. Question 6. Mg + 2HCl ⇨ MgCl 2 + H 2. Which gas is liberated when a metal reacts with an acid? Question 27. Name two metals which will displace hydrogen from dilute acids and two metals which will not. There are a few highly reactive metals, which react with dilute acids, water, and oxygen, and include potassium, sodium, lithium, and calcium, to name a few. (CBSE 2011) Answer: Hydrogen gas is formed. When zinc reacts with dilute hydrochloric acid (a) the surface of zinc becomes brighter (b) the surface of zinc becomes black and dull (c) the metal turns into powder Sodium reacts violently with dilute mineral acids and displaces hydrogen from them. asked Jun 22 in Chemistry by Renu01 (52.6k points) materials; metals and non metals; class-8; 0 votes. Reaction of magnesium metal with dilute hydrochloric acid: Magnesium chloride and hydrogen gas are formed when magnesium reacts with dilute hydrochloric acid. When a metal react with dilute nitric acid,then hydrogen gas is not evolved.Nitric acid is a strong oxidising agent.As soon as hydrogen gas is formed in reaction between metal and dilute nitric acid,the nitric acid oxidises this hydrogen to water.Nitric acid itself is reduced to nitrogen oxides such as nitrogen monoxide,dinitrogen monoxide. It is because HNO 3 is a strong oxidising agent. The metal which reacts violently with cold water is: (a) zinc (b) aluminium (c) sodium (d) copper. (CBSE 2011) Answer: Magnesium Question 25. Question 1. HCl) and bases (dil. View Answer. Name a non-metal that conducts electricity. When zinc metal reacts with dilute hydrochloric acid, the gas evolved (a) supports combustion (b) turns lime water milky (c) bums with a pop sound (d) has a pungent odour. Bring a burning matchstick near to it, H 2 will burn explosively with ‘pop’ sound. The gas produced when metals reacts with dilute acids is: (a) nitrogen (b) carbon dioxide (c) oxygen (d) hydrogen. Name the metal which reacts with a very dilute HNOs to evolve hydrogen gas. For acids such as dilute hydrochloric acid and dilute sulfuric acid the general equation for their reaction with reactive metal is. Al, Fe, Zn react with steam to from metal hydroxide & H2. Answer Name one metal which reacts with dilute hydrochloric acid to produce hydrogen gas. 1 answer. Reaction with dilute Acids: Metal + Dilute Acid → Salt + H2. Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g) Metal + HNO3 → H2 not evolved. Na & K: react violently with cold water. The metal X reacts with dilute hydrochloric acid to form a gas Y. CBSE Class 10 Science Lab Manual – Properties of Acids and Bases EXPERIMENT 2(a) Aim To study the properties of acids (dil. Ca: reacts less violently.
