CBSE 10 Science 01 Chemical Reactions and Equations 5 Topics | 6 Quizzes 1.1 Chemical Reaction 1.1 Chemical Reaction - … Answer: Redox (reduction–oxidation, pronunciation: / ˈ r ɛ d ɒ k s / redoks or / ˈ r iː d ɒ k s / reedoks) is a type of chemical reaction in which the oxidation states of atoms are changed. a) Total mass of reactants 73g products 73g 2, Mg → Mg2+ +2e–, Question 3. c) Cl (i) Mg → Mg2+ + 2e– (Oxidation) H2 is the reducing agent and Cl2 is the oxidizing agent. reactions. Therefore, redox reaction is also known as oxidation-reduction reaction. Hence 2 + x – 8 = 0 b) Situation 2: ………………. Answer: Analyze the following equation fill-up the blanks. When surface area increases rate of reaction also increases. Redox reaction: These are oxidation and reduction reaction that describes all chemical reactions in which the oxidation number is decreased or increased. b) Suppose you want to increase the rate of reaction again. No . Some materials available in the laboratory are given below. Consequently the rate of reaction increases. Question 63. Common Redox Reactions. Redox Reactions. What is the relation between rate of reaction and surface area? Note down the number of atoms in the reactant side and the number of atoms in the product side in the table below. Which way you would choose? Mg → Mg2+ + …………… The reduced atom is … All the magic that we know is in the transfer of electrons. Classification of Redox Reactions. O, Question 38. Here sodium is the reducing agent and chlorine is the oxidizing agent. In the formation of hydrogen chloride does the oxidation number of hydrogen increase or decrease? The substance that causes oxidation is called the oxidising agent or oxidant. Reducing agent – C Answer: Now add some manganese dioxide (MnO2) into the test tube. Step I: H2+ O2 → H2O The substance remaining in the filter paper is manganese dioxide itself When examined carefully it becomes clear that there is no change in its amount or property. 3. These reactions find extensive use in pharmaceutical, biological, industrial, metallurgical and agricultural areas. The process in which the oxidation number increases is called oxidation. b) The oxidized atom is Question 29. 2. How many product molecules are needed to equalize the number of oxygen atoms on both sides? Question 74. [2×(+1)] + x + (4x – 2) = 0 Eg. 2Mn + -2×7 = 0 Answer: Same, Question 64. What is meant by Redox reaction? Add a piece of Mg m to one of them. H Oxidation state of potassium = +1 f) Reducing agent Step II: 2Al+ 3O2 → 2Al2O3, Question 23. Na → Na++1e– CO2 + C2CO.

Let the oxidation state of sulphur be ‘x’ We know the sum of oxidation states of all atoms in a compound is zero. a) Which gas is formed here? CuO + H 2 → Cu +H 2 O. The electronic configuration of magnesium and chlorine are 2, 8, 2 and 2, 8, 7 respectively. The process in which the oxidation number decreases is called reduction. Based on oxidation number which is the oxidizing agent and reducing agent? Procedure: Prepare dilute solution of sodium thiosulphate in a beaker. Answer: Balance the chemical equation Al + O2 → Al2O2 Some apparatus and chemicals are given. Oxidation number of hydrogen decrease from +1 to 0 The reducing agent is zinc and oxidising agent is HCl. b) Suggest any two ways you would choose to increase the rate of this chemical reaction. Take equal volumes of this solution in two boiling tubes. Question 70. Fe + 2HCl → FeCl2 + H2 What is redox couple? Which is the product? In heated test tube, Question 72. a) Design an experiment to prove that the nature of reactants can influence the rate of reaction. It will get extinguished. Zn, Question 50. Answer: … Answer: Now rewrite the equation Answer: A reaction involving both a reduction process and a oxidation process is called a redox reaction. Zigya App. Mn = +4, Mn2O3 Chlorine (Cl), Question 33. Answer: 2Mn + 2x -2 = 0 F+ le– → F– Sulfur pieces do not react with cold concentrated nitric acid. Answer: Both are equal. It converts the single compound into two compounds, in which one is of higher oxidation state, and … Answer: Mg → Mg2+ + 2e–, Question 27. In a chemical reaction mass is neither created nor destroyed. 1. Question 10. HSSlive chemistry redox reactions Question 1. x – 7 =0 Zn, Mg, dilute HCl, CaCO3, test tube, water. C + O2 → CO2 There are generally two methods for balancing redox reactions (chemical equations) in a redox process. a) Which materials will you choose for the preparation of more CO2 in less time? H 2 is getting oxidised to H 2 O. Write down the total mass of the reactants and the total mass of product in the above experiment. How many Zn atoms are there in the reactant side and in the product side? This energy is called threshold energy. What are catalysts? Take equal volume of dil.
