name a metal that reacts violently with dilute acids

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