Ammonia gas combines with solid copper(II) oxide to yield nitrogen gas, copper metal, and steam.
Part 1: What is the unbalanced equation (no stoichiometric coefficients, reactants on left, products on right, separated by an arrow, and phases are not necessary).
Part 2: What is the balanced equation in standard form? Stoichiometric coeffcientst should be the lowest set of whole numbers
Part 3: How many moles of H2O can be formed when 4.50g of CuO are combined with 4.50 x 1023 molecules of ammonia. (three significant figures)? (If the balanced equation is not correct for part B, this part will most likely be incorrect)

Solid copper can be produced by passing gaseous ammonia over solid copper (II) oxide at high temperatures. The other products of the reaction are nitrogen gas and water vapor. The balanced equation for this reaction is: 2NH3(g)+3CuO(s)->N2(g)+3Cu(s)+3H2O(g) What is the theoretical yield of solid copper that should form when 18.1 g of NH3 is reacted with 90.4 g of CuO? If only 45.3 g of copper is actually collected, what is the percent yield?
Nitrogen gas can be prepared by passing ammonia over copper(II) oxide, and the other products are copper metal and water vapor. If a sample containing 3.58 moles of NH3 is reacted with excess copper(II) oxide, how many grams of N2 will be formed?
Nitrogen gas can be prepared by passing ammonia over copper(II) oxide, and the other products are copper metal and water vapor. If a sample containing 2.63 moles of NH3 is reacted with excess copper(11) oxide, how many grams of N, will be formed?
Nitrogen gas can be prepared by passing ammonia over copper(II) oxide, and the other products are copper metal and water vapor. If a sample containing 3.46 moles of NH, is reacted with excess copper(II) oxide, how many grams of N, will be formed?
1. Write a balanced chemical equation for the oxidation of zinc metal (Zn) by copper(II) ions (Cu?") in a copper sulfate solution. Note that copper(II) sulfate completely dissociates in aqueous solution and forms Cu2+ (aq) and SO,- (aq) in water. Zinc metal is a solid and should be represented as Zn (3) Write a chemical equation for the decomposition of limestone (CaCO,) by heating to high temperature to drive off carbon dioxide. The other product of this decomposition reaction is...
1 Reaction C: Copper(II) Hydroxide to Copper(IT) Oxide Observations: The solntich goes from a light blue to a dark blue. when heated the solution turns to a green/black color. Balanced Molecular Equation: Balanced Net lonie Equation: Reaction D: Copper(IT) Oxide to Copper(II) Sulfate Observations: "The back sond is dissolved in the acid. This creates a light blue / Clear solurich Balanced Molecular Equation: Balanced Net Ionic Equation: Reaction E: Copper(II) Sulfate to Copper Metal (and Dissolution of excess Mg) Observations:...
