2017年5月20日 · Hydrogen gas, H2, reacts with nitrogen gas, N2, to form ammonia gas, NH3, according to the equation 3H2(g)+N2(g)→2NH3(g) a. How many moles of NH3 can be produced from 18.0 mol of H2 and excess N2? b. How many grams of NH3 can be produced from 3.46 mol of N2 and excess H2. c. How many grams of H2 are needed to produce 13.36 g of NH3? d.

2023年3月12日 · So the number of moles of H2 required is 1.021 mol N2 * 3 mol H2/1 mol N2 = 3.063 mol H2 (notice that mol N2 canceled out, so the equation is set up correctly) However, the question ask for number of grams of H2 needed, so we need the molar mass of hydrogen gas or H2, which is 1*2 = 2 g/mol

2024年10月10日 · 4. Ammonia is produced by the chemical reaction of nitrogen and hydrogen. N2 (g) + 3H2(g) →→ 2NH3 (9) (A) Calculate the number of moles of hydrogen, H2, needed to react with 1.80 moles of nitrogen, N2. (5 points) (B) Calculate the grams of NH3 formed when 2.4 moles of H2 reacts completely with sufficient amount of N2. (5 points)

2023年11月6日 · The reaction N2 + 3H2 → 2NH3 is not classified as a double replacement or redox reaction. It is actually a synthesis reaction, which is a type of chemical reaction where two or more reactants combine to form a single product. In this case, nitrogen gas (N2) and hydrogen gas (H2) react to form ammonia (NH3).

2019年7月31日 · ammonia is produced according to the reaction: 3h2 n2 --> 2nh3 if 17.78 g of h2 react with 44.41 g of n2, what mass (in grams) of ammonia can be produced? Community Answer This answer was loved by 1 person

In the reaction N2 + 3H2 = 2NH3, we are looking at a redox process, where one species is being oxidized and another is being reduced. To identify the changes in oxidation state, we assign oxidation numbers before and after the reaction. Nitrogen (N2) has an oxidation state of 0, as it is in its elemental form.

3h2 +n2 →2nh3 Now, the equation is balanced, indicating that three molecules of hydrogen gas react with one molecule of nitrogen gas to produce two molecules of ammonia. This correct answer is a)
