Le soleil brillait, les gens souriaient, et je me sentais tranquille. Je me promenais dans le parc quand tout à coup j’ai vu mon ami Marc. Il marchait vers son bureau mais dès qu’il m’a aperçu, il s’est arrêté pour bavarder un peu. Nous discutions de nos familles quand il a commencé à pleuvoir. Nous avons continué à parler pendant quelques moments et puis j’ai dû retourner au travail.

QUESTION 8 Nitric аcid (HNO3) is used in the prоductiоn оf fertilisers. Nitric аcid is mаnufactured in three stages.· STAGE 1 - ammonia reacts with oxygen in the presence of a platinum catalyst to produce nitrogen monoxide gas, NO, and water.· STAGE 2 - nitrogen monoxide gas reacts with more oxygen to produce nitrogen dioxide gas, NO2 . · STAGE 3 - nitrogen monoxide gas reacts with water to produce nitric acid and more nitrogen monoxide gas. a(i) Complete the chemical equation for the reaction in stage 1. ...........NH3 + ..........O2 ↔ .......... NO + ........... H2O (1) a(ii) State the purpose of the platinum catalyst. (1) b Give a chemical equation for the reaction of nitrogen monoxide and oxygen in stage 2. (1) c(i) The equation for the reaction in stage 3 is 3NO2 + H2O → 2HNO3 + NO Calculate the maximum mass, in tonnes, of nitric acid that could be produced in this reaction from 13.8 tonnes of nitrogen dioxide. [1 tonne = 1.0 × 106g] (4) c(ii) Suggest what use can be made of the nitrogen monoxide gas formed in stage 3. (1) d When copper(II) oxide reacts with dilute nitric acid, copper(II) nitrate is produced. The equation for the reaction is CuO + 2HNO3 → Cu(NO3)2 + H2O 0.200 mol of nitric acid reacts with excess copper(II) oxide. A mass of 15.3 g of copper(II) nitrate is produced. Calculate the percentage yield of copper(II) nitrate. [Mr of copper(II) nitrate = 187.5] (3) [11]
