B: X + water → ammonia + another compound C: Ammonia + metal oxide → metal + water + N 2 . Another way to prevent getting this page in the future is to use Privacy Pass. NH3 is your limiting reactant since "an excess of CuO" is present, so you must find the moles of this (grams divided by molar mass) and use that number. = 79.5 g/mole). Balance that equation NH3+CuO --- Cu +N2 + H2O ANSWER:- 2NH3 + 3CuO --- 3Cu + N2 + 3H2O HOPE IT'S HELP YOU ANY DOUBTS YOU CAN ASK ME THANK YOU Please register to post comments. Substitute immutable groups in chemical compounds to avoid ambiguity. In the presence of 50 ppm NH 3, the results showed that CuO/TiO 2 catalysts could still maintain 98–100 % of Hg 0 conversion in the range of 100–400 °C, while the catalytic performance of … 2, 3, 4 C. 1, 2, 3 D. 3, 4, 5 Xem đáp án câu 2 Compound states [like (s) (aq) or (g)] are not required. Enter either the number of moles or weight for one of the compounds to compute the rest. Question: V. _ NH3(g) + _ Cuo(s) → _N2(g) + - _Cu(s) + _H20(9) 16. 1 decade ago. CuO: 3: 79.5454: N 2: 1: 28.0134: Cu: 3: 63.546: H 2 O: 3: 18.01528: Units: molar mass - g/mol, weight - g. Please tell about this free chemistry software to your friends! A vacuum layer of 10 Å was added along the z direction to construct the slab supercell models. 18.

Phương trình hoá học có chứa chất tham gia CuO NH3 và chất sản phẩm Cu H2O N2 kèm trạng thái chất, màu sắc và phân loại phương trình Add / Edited: 04.10.2014 / Evaluation of information: 5.0 out of 5 / number of votes: 1. The CuO (111) and Cu 2 O (111) surfaces from the corresponding optimized primitive cell were constructed with a p(3 × 3) supercell and six atomic layers. The following reactions are carried out: A: Nitrogen + metal → compound X. If you do not know what products are enter reagents only and click 'Balance'. Phương trình hoá học có chứa chất tham gia CuO NH3 và chất sản phẩm Cu H2O N2 kèm trạng thái chất, màu sắc và phân loại phương trình With solid CuO and supply of heat, ammonia is oxidized to nitrogen gas and CuO is reduced to copper. 4, 5, 6 B. If 18.1 g of NH 3 are reacted with 90.4 g of CuO, which is the limiting reagent?How many grams of N 2 will be formed?. Cuperic oxide is in essence "rusted" copper.... a rather strong bond between the copper and the oxygen. Examples: Fe, Au, Co, Br, C, O, N, F.     Compare: Co - cobalt and CO - carbon monoxide, To enter an electron into a chemical equation use {-} or e. To enter an ion specify charge after the compound in curly brackets: {+3} or {3+} or {3}. Reaction stoichiometry could be computed for a balanced equation. One metal that can be used for reaction A is magnesium. One metal that can be used for reaction A is magnesium. = 17.031 g/mole) and the number of moles of CuO (M.W. ChemiDay you always could choose go nuts or keep calm with us or without. Finding the grams of N2 and CuO from that molarity is just multiplication. 17. a.Viết ptpu. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. Balance The Equation. NH3 +CuO = Chất rắn A + Hỗn hợp khí B. Nhờ các bạn giải giúp Cho lượng khí NH3 đi từ từ qua ống sứ chứa 3,2g CuO nung nóng đến khi phản ứng xảy ra hoàn toàn ; thu được rắn A và 1 hỗn hợp khí B.
