Chất rắn A phản ứng vừa đủ với 20 ml HCl 1M. 17. Copper oxide (CuO) is a black solid and produced copper has red-brown color. How Many Grams Of Which Reactant Will Be Left Over? 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 … Cloudflare Ray ID: 5f9a251d6daad37a = 17.031 g/mole) and the number of moles of CuO (M.W. 2, 3, 4 C. 1, 2, 3 D. 3, 4, 5 Xem đáp án câu 2 Lv 6. Balance The Equation. a.Viết ptpu. The following reactions are carried out: A: Nitrogen + metal → compound X. Enter either the number of moles or weight for one of the compounds to compute the rest. Hiện tượng: có hiện tượng khí thoát ra. B: X + water → ammonia + another compound C: Ammonia + metal oxide → metal + water + N 2 . First we compute the number of moles of NH 3 (M.W. Another way to prevent getting this page in the future is to use Privacy Pass. I hope this helps you. The following reactions are carried out: A: Nitrogen + metal → compound X. 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?. Not necessarily. One metal that can be used for reaction A is magnesium. • 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.

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. It would depend upon how strong the bond between the oxygen or oxide is. 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. In many cases a complete equation will be suggested. Question: V. _ NH3(g) + _ Cuo(s) → _N2(g) + - _Cu(s) + _H20(9) 16. If you do not know what products are enter reagents only and click 'Balance'.
