The reason why is because Copper is very unreactive , One of the last few in the reactivity series and its reduction potential is higher . Please register to post comments. Cu + 2H2SO4 + 2e- ---> Cu2+ + 2e- + SO4(2-) + SO2 + 2 H2O. Sulfur trioxide (SO3) gas reacts with water (H2O) to form sulfuric acid (H2SO4). Nếu cho hỗn hợp trên phản ứng với dung dịch H2SO4 đặc nguội dư thu được 8,96 khí SO2 (sản phẩm khử duy nhất, ở đktc). So, since there is one Cu product, it must have come from one Cu originally. Balancing result for chemical equations: cu (copper) h2so4 (sulfuric acid) = h2o (Water; Hydrogen oxide; Drinking water; Steam) so2 (sulfur dioxide) cuso4 (copper(ii) sulfate) . Phương trình hoá học có chứa chất tham gia Cu H2SO4 và chất sản phẩm H2O SO2 CuSO4 kèm trạng thái chất, màu sắc và phân loại phương trình You need to be careful with the small and capital letters because they have different meaning. Add / Edited: 18.08.2015 / Evaluation of information: 5.0 out of 5 / number of votes: 1. directly helping charity project in Vietnam building shcools in rural areas. Sulfuric Acid - H 2 SO 4. BUT note there are one SO4 and also one SO2 and one H20 which could only have been derived from an SO4 group from the LHS. 1 Chuỗi :H2SO4-> H2->Cu->Cuo->H2O-> Ca(OH)2->CaCO3(1) (2) (3) ( 4) (5) (6)2 . Nếu bạn đăng câu hỏi kèm NHỮNG GÌ MÌNH ĐÃ LÀM ĐƯỢC, bạn sẽ nhận được những chia sẻ TẬN TÌNH Yes, it will react to make copper sulphate and waterCu(OH)2 + H2SO4 --> CuSO4 + 2 H2O. All questions on Chemistry. Reaction Information. A. Fe(OH) 2. identify solutions Cu(NO3)2 AgNO3 NaCl ID 458280. Cu + 2H 2 SO 4 → CuSO 4 + SO 2 + 2H 2 O. 1-Methylimidazolium hydrogen sulfate. Phenomenon: Red solid of copper (Cu) dissolves gradually in solution, and bubbles appear when sunfur dioxide (SO2) is created. Answers. Сoding to search: CuO + H2SO4 = CuSO4 + H2O. Cho 1,92 gam bột Cu vào 100 ml dung dịch hỗn hợp (gồm KNO3 0,16M và H2SO4 0,5M) thu được dung dịch X và khí NO (sản phẩm? CuO plus H2SO4 --> H2O + CuSO4. Co is cobalt. Zn is more reactive than is Cu, so it will replace the Cu. To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. ChemiDay you always could choose go nuts or keep calm with us or without. 11,2 C. 16,8 D. 1,12 Xem đáp án câu 1 B. Fe(OH) 2, Cu(OH) 2 C. Fe(OH) 3, Cu(OH) 2 D. Fe(OH) 3. The reaction above is between copper metal and heated NON-aqueous (aka concentrated H2SO4). There will be NO products Form when reacting Copper with Sulfuric Acid. Cu = 63.55g/mol. This is an unfortunately common reaction that occurs in the atmosphere in some places where oxides of sulfur are present as pollutants. Reactants. Become a Patron! hyastian2829 hyastian2829 Answer: It's B . Most of the Co and Mn contents were leached within half an hour of reaction in the presence of Cu(II)/SO 2 when cobalt was associated with manganese minerals. Compound states [like (s) (aq) or (g)] are not required. Cu có phản ứng H2SO4 nhưng chỉ tác dụng với dung dịch đặc nóng thôi và giải phóng ra SO2. ); The Gold Parsing System (Hats off! Add your answer and earn points. Joe S. 02 May 2016. So, since there is one Cu product, it must have come from one Cu originally. Thus, the reaction isZnSO4 + Cu ==> CuSO4 + Zn.

Zn is more reactive than is Cu, so it will replace the Cu. 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. D. 36,82. H2SO4 has the lowest amount of moles as compared to Cu, therefore is the Limiting reactant. Calculate the change in mass of cathode and that of the anode. În ploaia acidă, acidul sulfuric trece sub formă diluată (sulfat de hidrogen sau ioni de sulfat) și ajunge pe pământ. I will assume that you mean CuCO3 and H2SO4.
