CuO(s) + 2HNO3(aq) --> Cu(NO3)2(aq) + 2H2O(l) If the reaction is between CuO and citric acid, then the complete neutralization of the acid will produce copper citrate and water.

The oxide will dissolve in a minute or two…leaving a clear, aqua blue solution (the result of the formation of copper (II) chloride). Is there a way to chemically reduce suspension or solution containing copper (II) oxide powder, back to copper metal. The empirical formula is the smallest whole number ratio of copper to oxygen atoms. Likewise, how do you calculate the empirical formula of copper oxide? OR Select a Topic that Interests you. Copper(II) nitrate is poisonous if swallowed. In the case of a reaction between CuO and nitric acid, you will get copper(II) nitrate and water. From the equation, we know that 2 moles of copper(II) nitrate decompose into 2 moles of copper(II) oxide, 4 moles of nitrogen dioxide gas and 1 mole of oxygen gas. 6.1 Write down the balanced reaction of the above equation. ? This activity includes every compound formula and name that can be formed from the list 44 Ions provided in Chemistry A at Pickerington High School Central. At the microscopic level, the coefficients in a chemical reaction tell us the number of particles 1 involved in the reaction. To obtain the empirical formula divide the number of moles of both copper and oxygen by the smaller of the two numbers. Take a look at this word equation for the reaction: copper + oxygen → copper oxide. Add 25 mL of 3 M hydrochloric acid to the black copper (II) oxide in the beaker. Stir gently or cover with a watch glass and swirl gently. Conversion 4: CONVERTING COPPER (II) OXIDE TO COPPER (II) CHLORIDE 1. View complete question Question 6 When copper nitrate (Cu(NO3)2) is heated the copper nitrate decomposes to form copper oxide (Cuo), nitrogen dioxide (NO2) and oxygen (O2). When sulfuric acid and copper (II) oxide are allowed to react, copper (II) sulfate and water are formed. 5. 6.1.2 Use the Periodic Table to calculate the relative formula mass Mr copper nitrate. Actually, the nitrate ion oxidizes the copper metal to copper (II) ion while itself being transformed to NO 2 gas in the process; the copper (II) ion then binds to six water molecules. For example, copper and oxygen react together to make copper oxide. Write a balanced equation for this reaction. solid copper(II) nitrate is heated to produce solid copper(II) oxide, gaseous nitrogen dioxide and oxygen gas. After dividing by the smaller of the two numbers round each to the nearest whole number. When copper (II) sulfate and aluminum are allowed to react, aluminum sulfate and copper are formed.
