name a metal that reacts violently with dilute acids

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. Which gas is liberated when a metal reacts with an acid? Temperature – warm acid solutions attack metals faster than cold solutions. Answer Name a non-metal that conducts electricity. 14. 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. 1 answer. Answer (c) sodium Sodium reacts violently with cold water because it is high in the reactivity series. Video Explanation. Ca: reacts less violently. Acid + Metal → Ionic compound + Hydrogen gas Reaction with dilute Acids: Metal + Dilute Acid → Salt + H2. Mg: reacts with hot water. Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g) Metal + HNO3 → H2 not evolved. The metal X also reacts with sodium. View Answer. Question 25. (CBSE 2011) Answer: Magnesium Question 27. It oxidises the H 2 produced to water and itself gets reduced to any of the nitrogen oxides (N 2 O, NO, NO 2 ). 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 For acids such as dilute hydrochloric acid and dilute sulfuric acid the general equation for their reaction with reactive metal is. This shows that sodium is … Surface area of the metal – powdered metals react faster than large lumps. 2Al + 6HCl ⇨ 2AlCl 3 + 3H 2. Gas released in the following reaction will be: The metal X reacts with dilute hydrochloric acid to form a gas Y. Name one metal which reacts with dilute hydrochloric acid to produce hydrogen gas. HCl) and bases (dil. The metal which reacts violently with cold water is: (a) zinc (b) aluminium (c) sodium (d) copper. Reaction of aluminium with dilute hydrochloric acid: Aluminium chloride and hydrogen gas are formed. How will you test the presence of this gas? Answer: Graphite (carbon) is an example of a non-metal that conducts electricity. Sodium reacts violently with dilute mineral acids and displaces hydrogen from them. Question 6. Na & K: react violently with cold water. Question 1. 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. Al, Fe, Zn react with steam to from metal hydroxide & H2. The ability of metals to be drawn into thin wires is known as NaOH) by their reaction with Litmus solution (blue/red) Zinc metal Solid sodium carbonate Materials Required Test tubes, test tube stand, test tube holder, cork, droppers, boiling tube, match-box, burner, […] 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. Name two metals which will displace hydrogen from dilute acids and two metals which will not. Mg + 2HCl ⇨ MgCl 2 + H 2. 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. Name the metal which reacts with a very dilute HNOs to evolve hydrogen gas. Reason- HNO3 is strong oxidizing agent & oxidized H2 to water. The gas produced when metals reacts with dilute acids is: (a) nitrogen (b) carbon dioxide (c) oxygen (d) hydrogen. CBSE Class 10 Science Lab Manual – Properties of Acids and Bases EXPERIMENT 2(a) Aim To study the properties of acids (dil. (CBSE 2011) Answer: Hydrogen gas is formed. It is because HNO 3 is a strong oxidising agent. Cold, dilute nitric acid reacts with copper to form _____ (hydrogen, nitrogen dioxide, nitric oxide). asked Jun 22 in Chemistry by Renu01 (52.6k points) materials; metals and non metals; class-8; 0 votes. Bring a burning matchstick near to it, H 2 will burn explosively with ‘pop’ sound. Metals and Non-metals Class 10 MCQs Questions with Answers.
