Posted on December 15, 2019 Author Quizzer Categories Chemistry MCQs Class 9 Post navigation. CuO(s) + H 2 (g) → Cu(s) + H 2 O(g) Let us write the oxidation number of each element involved in the given reaction as: Here, the oxidation number of Cu decreases from +2 in CuO to 0 in Cu i.e., CuO is reduced to Cu. ints upwards So, cupric oxide is reduced to copper and hydrogen is oxidized to water. Reaction 2, in which copper (II) oxide, two hydrogen cations and five water molecules produce the hexaquacopper (II) ion, could technically be seen as two separate reactions. The answer is Redox reaction as well as displacement reaction because both reduction and oxidation takes place. CuO + H2 → Cu + H2O. Cu in CuO lost 2 electrons when converted to Cu(s). Fluorine reacts with ice and results in the change. ... B. Cu C. H2O D. CuO. I do Physics/Astronomy, not Chemistry. In (b), the copper(II)oxide is reduced to copper metal by the hydrogen gas, which removed the oxygen from it to form water. Combination reaction as well as double displacement reaction. Q. Consider The Reaction CuO(s) +H2(g) >> Cu(s) +H2O(l). CuO was oxidized. What is oxidation reaction? b)Both A and R are true but R is not the correct explanation of A. Solved: Identify the oxidizing and reducing agents in the equation. in this reaction the reducing agent is h2 and the oxidising agent is cuo . cuo is reduced to cu . For the equation: H2 + CuO ----> Cu + H2O (a) If 10.0 grams of hydrogen are reacted with CuO, how many grams of water will beproduced? 1.Magnesium is oxidized, copper is reduced, and silver is neither oxidized nor reduced. Reason(R): Cu is a less reactive metal. A.Both CuO(s) And Water Are Reducing Agents. asked Jun 8, 2018 in Chemistry by rubby (51.7k points) redox reaction; class-11; 0 votes. Hope it helps!!! Cu2+ + H2 -> Cu + 2H+ This reaction WILL occur, the one you gave WILL NOT. Write the balanced chemical equations for the following reactions (a) Sodium carbonate on reaction with hydrochloric acid in equal molar concentrations gives sodium chloride and sodium hydrogencarbonate. CuO + H2SO4 = CuSO4 + H2O(l) Change in Free Energy: ΔG(20C) = -79.9kJ (negative, so the reaction runs) Change in Enthalpy: ΔH(20C) = -85.9kJ (negative, so the reaction is exothermic) This is a double displacement, exothermic reaction. ʟᴏᴠᴇʀ.7. In many cases a complete equation will be suggested. Consider themetals in the following reactions. This fact may be explained taking into account that the reaction CuO + H 2 → Cu + H 2 O does not lead to a change in gas pressure, as corresponding amount of water vapor is formed in the reaction zone. ғɪʀsᴛ ʟᴏᴠᴇ.4. 17. Redox Reactions. As a result of chemical reaction is obtained salt with copper iodide and water. Reaction stoichiometry could be computed for a balanced equation.
