ANSWER:- 2Cu2O(s) + O2(g)4CuO(s) moles of Cu2O = 55.6/143 = 0.39 moles moles of O2 view the full answer Check if there are the same numbers of oxygen atoms on the left and right side, if they aren't equilibrate these atoms by adding water molecules. This is an example of a redox equation, the which we can address by separately treating the oxidation and reduction reactions…. Compound states [like (s) (aq) or (g)] are not required. We take in energy from food and we give out energy through work. You can use parenthesis or brackets []. Check all that apply. Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. 2CuSO 4 2CuO + 2SO 2 + O 2. Give two reasons why a 100% yield is not obtained in actual chemical manufacturing process. They are actually more covalent than ionic. 0. This reaction takes place at a temperature near 1800°C. In a particular redox reaction, Cr is oxidized to CrO4^2– and Cu2^+ is reduced to Cu^+ . Which is a good example of a contact force? Our bodies are perfect examples of that. Produces 8.0 Mol Of Cuo C. Must React With 256 G Of O2 D. Cannot React With Oxygen E. Produces 16.0 Mol Of Cuo 2. Copper also reacts with chlorine Cu + Cl2 CuCl2. So I broke it down into Net formula and got rid of the Cu and I got this : 2NO31- -----> O2- + NO2 + O2 ox. = 2NO31- -----> NO2 red. Oxidizing agent which helps in oxidizing and it is CuO Complete and balance the equation for this reaction in acidic solution. See if you can find examples of how our bodies are endothermic and exothermic. The Balanced Equation 2Cu(s) + O2(e) → 2Cuo(s) Tells Us That 8.0 Mol Of Cu A. Reacts With 8.0 Mol Of O2 B. Substitute immutable groups in chemical compounds to avoid ambiguity. The answer will appear below, Always use the upper case for the first character in the element name and the lower case for the second character. Chemical equations can be identified as … Why did scientists who study weather need more advanced technology? oxidized reduced.
