Copper (Cu) Copper is a reddish brown color metal and less reactive than other metals such as alkali metals and alkaline earth metals. Lv 4. Update: Ummm... Hi. a. CuO is very stable and therefore does not dissociate in water and therefore cannot react with the sulfate ion in potassium sulfate. 2 grams of pseudoephedrine are dissolved in 20ml acetone, and cooled in an ice bath. One or more statements may be true. CuO (s) + H 2 SO 4 (aq) → CuSO 4 (aq) + H 2 O (l) Sulfuric acid can also be used to displace weaker acids from their salts. 0 0. valdivia. No, H2SO4 is not acting as a reducing agent; in fact, that is not a redox reaction. The following reaction: 2NaOH(aq) + H2SO4(aq) → Na2SO4(aq) + 2H2O(l)was studied in a coffee cup calorimeter.

A redox reaction occurs when a substance loses electrons and the other gains electrons, i.e., their oxidation states are changed. CuO, 30 0 oC. When sulfuric acid and copper (II) oxide are allowed to react, copper (II) sulfate and water are formed. ď. Looking at the equation, you have a 1:1 reaction, meaning for every one mole of CuO you need one mole of H2SO4 in order to produce one mole of CuSO4 and one mole of H2O. 9 years ago. A redox reaction occurs when a substance loses electrons and the other gains electrons, i.e., their oxidation states are changed. Both reaction are redox reactions and have to consider about their oxidation numbers when reactions are being balanced. Yes, hydrogen will make bubbles.No. ċ.

So, the LHS must at a minimum start with TWO "H2SO4"s and one "Cu" which then produce one "CuSO4" and one SO2 and TWO "H2O"s. i.e. Neglect the heat capacity of the cup and the thermometer, and assume the solution of products has a density of 1.00 g/mL and a … These compounds undergo substitution and elimination very easily, often more reactive than alkyl halides. Cameron E. 1 decade ago. Reaction C: Cu(OH)2(s)-> CuO(s) + H2O(l) blue cupric hydroxide solid, Cu(OH)2, is decomposed with heating into the black cupric oxide solid< CuO. And that after adding the water it turned from green to blue. This reaction is congruent with the Lowry Theory of Acids and Bases, so this could be defined as a Acid-Base reaction. 4 years ago. I know it isn't redox... Is this acid/base reaction? 0 0. Well, the CuO and H2SO4 react one mole to one mole, and .80g of CuO is 79.5 g/mol, or .0101 moles of CuO. If the answer is yes, in what conditions does the reaction take place? I don't know if $\ce{C}$ or $\ce{CuO}$ react with $\ce{H2SO4}$. Cyclohexanol will not reduce with LiAlH 4, but the corresponding tosylate reduces to cyclohexane very easily. Identify Oxidations and Reductions b) For each redox reaction… Copper Oxide + Sulphuric Acid = Acid + Base = Salt + Water. Well, because you know this, just you know how many moles required in the reaction, and you know the concentration of the thing you want. This is a Decomposition reaction because it is breaking down Cu(OH)2 into two differend molecules. Also can be looked at as a reduction reaction. Reaction 4: Converting copper oxide to copper sulfate CuO + H2SO4 -----> CuSO4(aq) + H2O(l) Reaction 5: Converting copper sulfate back to copper metal CuSO4(aq) + Zn(s) -----> ZnSO4(aq) + Cu(s) In the first reaction, we saw how the copper was dissolved in to a green liquid in the beaker releasing a brown gas (toxic). (just one Cu) Cu + 2(H2SO4) --> CuSO4 + SO2 + 2(H2O) (.0101 mol) * (1000 mL/6.0 mol) = 1.677 mL of 6.0M H2SO4. Relevance. First convert 0.80g of CuO to moles utilising the molar mass of CuO. 1.06 grams CrO3 are added to .92ml H2SO4, and distilled water is added to bring the total volume to 4ml. Answer: 3 question This question involves a reaction between copper oxide, CuO, and sulfuric acid, H2SO4: CuO+H₂SO₄→CuSO₄+H₂O What mass of water is produced when 2.0 g of copper oxide reacts with an excess of sulfuric acid? 5 CuSO4 (aq) + Zn (s) →ZnSO4 (aq) + Cu (s) Precipitation After adding all the Zinc there was still a blue hue left, so more zinc was added until it was a clear liquid. Get an answer for 'Which type of chemical reaction is CuCO3 `->` CuO+CO2 ?' Now, we will study briefly about reactants, copper and HNO 3. CuO plus H2SO4 --> H2O + CuSO4. Nitric acid - HNO 3. O2 slowly reacts with Cu to produce CuO, and this will dissolve in the acid to give Cu2+ ions. 3MnO2 + 4A1 3Mn + 2A120, C. MgCO… A. CuO + H2SO4 → CuSO4 + H2O B. Reactants - Cu and HNO 3. CuO (s) + H2SO4(aq) → CuSO4(aq) + H2O(l) Ionic equation: CuO(s) + 2H+(aq) + SO4 2-(aq) → Cu2+(aq) + SO4 2- (aq) + H2O(l) Net ionic equation: CuO(s) + 2H+ → Cu 2+(aq) + H2O(l) 3 1. daviss. Then use the mole ratio from the balanced … The maximum temperature achieved was 30.6°C. Write a balanced equation for the reaction. The acid dissociates one H+ ion, that is likely to be absorbed by the CuO molecule, and then turned into the insoluble CuOH molecule. Also, copper can react with H2SO4 in the presence of oxygen. 4 years ago. Substitution reaction. That is an acid-base reaction. Consider that CuO(s) + H2SO4(aq) reacts to give CuSO4(aq) and CuO(s) + K2SO4 does not give a product. Comments. Mixing copper oxide and sulphuric acid is an experiment involving an insoluble metal oxide which is reacted with a dilute acid to form a soluble salt.Copper (II) oxide, is a black solid, which, when reacted with sulphuric acid creates a cyan-blue coloured chemical called copper II sulfate.
