Join Yahoo Answers and get 100 points today. 3Fe(s) + 4H2O(g) steam -----> Fe3O4 (s) + 4H2(g) b) calcium with water: The black copper oxide that is produced can be restored to original copper color through a reaction with hydrogen. Use the chemical equation to complete the activity. In chemistry experiments, this reaction can be sparked by heating copper with a burner, turning the original copper black. Not all metals react with water. C 14. the chemical equation between magnesium sulfate and water can be given as below . All rights reserved. if 6.13 X 10^24 atoms of oxygen are present, how many grams of oxygen do you have? Reaction of copper with water. 2Cu+S→Cu2S Copper (Cu) reacts with sulfur (S) to form copper sulfide as shown in the chemical equation. In fact you get a brown precipitate of copper and a blue solution of copper(II) sulphate because of the disproportionation reaction. Then turn out the Bunsen burner. So I used copper (I): Cu + Br2 -> CuBr Balanced: 2Cu + Br2 + 2CuBr2 But then our teacher used Copper 2 and got a totally different balanced equation: Cu + Br2 -> CuBr2 How do you know which copper to use or does it … express your answer as a balanced chemical equation. It may be wise to check (using pH or litmus paper) that no acid remains. The reaction equations will follow some simple rules. However, it is the hydrated form of the salt and has 5 water molecules. Answer: a. Mg reacts with hot water liberating hydrogen, Copper does not react with hot water. C 13. Cu(OH)2(s) J CuO(s) + H2O(g) Equation 3 Reaction 4: Copper Oxide and Sulfuric Acid But nitrogen in nitric acid is reduced from +5 to +4 by producing nitrogen dioxide which is a brown color and acidic gas. A black solid, it is one of the two stable oxides of copper, the other being Cu 2 O or copper(I) oxide (cuprous oxide). Nitrogen Dioxide and Water Reaction | NO 2 + H 2 O. Nitrogen dioxide (NO 2) is an acidic gas and readily reacts with water (H 2 O) to produce an acidic solution of nitric acid (HNO 3) and nitrogen monoxide (NO).Brown color of nitrogen dioxide gas is disappeared when reaction occurs. b. Copper metal is stable in air under normal conditions. This makes the body of the tank weaker and weaker and this can be dangerous. Video Transcript. Copper coils are used in several electrical appliances. Still have questions? Cu(s) + H2SO4(aq) → Cu2+(aq) + SO42-(aq) + H2(g). Copper metal also dissolves in dilute or concentrated nitric acid, HNO3. Write and balance the equation for this reaction. Copper does not react with water. Define multi-charged polynuclear complexes? Copper reacts with hot, concentrated sulfuric acid to form copper (2) sulfate, sulfur dioxide and water. Quick lime reacts vigorously with water to produce slaked lime with the release of large amount of heat. Copper metal dissolves in hot concentrated sulphuric acid to form solutions containing the aquated Cu(II) ion together with hydrogen gas, H2. When the funnel is removed, the copper turns black again. The copper oxide can then react with the hydrogen gas to form the copper metal and water. Express your answer as a … The reaction between copper metal and the halogens fluorine, F2, chlorine, Cl2, or bromine, Br2, affords the corresponding dihalides copper(II) fluoride, CuF2, copper(II) chloride, CuCl2, or copper(II) bromide, CuBr2 respectively. 1.) A 10. Note that the copper is still in the form of Cu+2, that is, it has not undergone oxidation or reduction. Thanks! Question: Copper Metal Reacts With Hot Concentrated Sulfuric Acid Solutionto Form Aqueous Copper (II) Sulfate, Sulfur Dioxide Gas, And Water. So we are suppose to write the balanced chemical equation for when copper reacts with bromine gas. Therefore, cannot be kept. Can Anyone Help Me Write This Equation And Balance It? At read heat, copper metal and oxygen react to form Cu2O. 13 points When magnesium reacts with hot water what happens by giving a balance chemical equation? If ice is less dense than liquid water, shouldn’t it behave as a gas? If the acid has not been hot enough, excess acid can co-exist with copper oxide. Explanations (including important chemical equations): 2 Cu (s) + O 2 (g) ---> 2 CuO (s) CuO (s) + H 2 (g) ---> Cu (s) + H 2 O (g) Heated copper metal reacts with oxygen to form the black copper oxide. Mg + H2O ——>MgO + H2 (iii) Zinc reacts only with steam. Copper(II) oxide or cupric oxide is the inorganic compound with the formula CuO. For example, if you react copper(I) oxide with hot dilute sulphuric acid, you might expect to get a solution of copper(I) sulphate and water produced. Solid iron(III) oxide reacts with hydrogen gas to form solid iron and liquid water. In practice, the Cu(II) is present as the complex ion [Cu(OH 2) 6] 2+. A base is a metallic hydroxide. It is either magnesium + sulfuric acid = magnesium sulfate + hydrogen or copper + sulfuric acid = copper sulfate + hydrogen the part that says some thing acid could be any acids. A more active metal will react more readily with water than a less active metal. The natural changes that happen to copper objects make them a one-of-a-kind symbol of heritage that s hard to replicate. P atm= 656.7, T h20= 27 C, V initial= 0.30 mL, V final = 17.05 mL and mass of Alka-seltzer 0.123g. (ii) Magnesium reacts with hot water or steam. C 8. Therefore, can be kept.
