If the word equation is incomplete, complete it and write the balanced chemical equation. Avoid spilling it on yourself. It is above copper in a metal reactivity series, so copper cannot replace the hydrogen in "HCl" to form "CuCl"_2. Cu + HCl = CuCl2 + H2 - Chemical Equation Balancer. E. Identify the precipitate (if any) that forms when Na 2 S and CdSO 4 are mixed. The Calitha - GOLD engine (c#) (Made it … For this type of reaction to occur, the reduction potential of the reactant receiving the electrons must be lower than the reduction potential of the reactant giving up electrons. In this case the activity series tell's us there's no reaction. A. Cu(s) + HNO3 (aq) ---->Cu(NO3)2 (aq) + NO2 (g) + H2O(l) Caution: Nitric acid is extremely corrosive. In the ion-electron method (also called the half-reaction method), the redox equation is separated into two half-equations - one for oxidation and one for reduction. There will be no reaction. Conversion of copper to copper II nitrate. Give reason(s) for the product(s) 1. barium chloride + sodium sulfate → 2. calcium + hydrochloric acid → 3. iron(II) sulfide + hydrochloric acid → hydrogen sulfide (g) + 4. zinc chloride + ammonium sulfide → 5. Write and balance a chemical equation that describes the reaction of {eq}Cu(NH_3)4SO_4 \cdot H_2O {/eq} with hydrochloric acid in aqueous solution. But this reaction is different from typical metal - acid reaction because nitric acid is an oxidizing acid.. Cu + HNO 3 reacts in different ways and give different products. Read our article on how to balance chemical equations or ask for help in our chat. Write a balanced equation for the reaction of NaCH 3 COO and HCl . If it is spilled on your clothes, Each of these half-reactions is balanced separately and then combined to give the balanced redox equation. Copper reacts in two ways with nitric acid. ); The Gold Parsing System (Hats off! Identify the precipitate (if any) that forms when NaCH 3 COO and HCl are mixed. Reaction Information. Balanced Chemical Equation. D. Write a balanced equation for the reaction of KOH and Cu(NO 3 ) 2 . You can also ask for help in our forums. Copper will not react with hydrochloric acid. What a great software product!) Each of these half-reactions is balanced separately and then combined to give the balanced redox equation. In this case the activity series tell's us there's no reaction. So in summary, by simply looking at the Activity Series you can predict which redox reactions will occur and which won't. Copper is a very unreactive metal, and it does not react with hydrochloric acid. "Cu(s) + HCl(aq)"rarr"no reaction" If you do, rinse it immediately with a great deal of water and call your instructor. Cu + 2 HCl → CuCl 2 + H 2. C.Identify the precipitate (if any) that forms when KOH and Cu(NO 3 ) 2 are mixed. According to the concentration of HNO 3 acid solution, products given by the reaction with copper are different. how about when Cu metal is put into a beaker of HCl (aq)? B. Copper and Nitric Acid Reaction | Cu + HNO3. Examples of complete chemical equations to balance: Fe + Cl 2 = FeCl 3; KMnO 4 + HCl = KCl + MnCl 2 + H 2 O + Cl 2; K 4 Fe(CN) 6 + H 2 SO 4 + H 2 O = K 2 SO 4 + FeSO 4 + (NH 4) 2 SO 4 + CO; C 6 H 5 COOH + O 2 = CO 2 + H 2 O Tell the type of reaction. Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. This program was created with a lot of help from: The book "Parsing Techniques - A Practical Guide" (IMHO, one of the best computer science books ever written. In the ion-electron method (also called the half-reaction method), the redox equation is separated into two half-equations - one for oxidation and one for reduction. ØWhat mass of Cu is deposited if a current of 1.50 Aflows for 1.00 hourin the electrolysis of a CuSO4 solution? Mossy zinc beakers Hydrochloric acid Procedure: A. The reaction: Cu2+ (aq) + 2e-→ Cu (s) time → charge → mol e-→ mol Cu → g Cu 1.00 hr x 60 min x 60 sec x 1.5 C x 1 mol e-x 1 mol Cu x 63.55 g Cu = 1 hr 1 min sec 96,487 C 2 mol e-1 mol Cu = 1.78 g Cu … There will be no reaction.
