(iv) What do you observe when ammonia is passed over copper oxide ? In general, to balance an equation, here are the things we need to do: The steps are simple, but it is a process of trial and error. Answer: Nitric oxide is oxidized by the oxygen of air to form brown coloured nitrogen dioxide : Question 25: Nitric oxide gives a black colour with ferrous sulphate solution. (b) Platinum. Therefore, the removal of these catalyst poison from nitrogen and hydrogen is very essential. 17. There are 4 hydrogen (H) atoms on the reactants side and 2 hydrogen (H) atoms on the products side. Let's take a look at an equation representing a chemical reaction: In this chemical reaction, nitrogen (N2) reacts with hydrogen (H) to produce ammonia (NH3).The reactants are nitrogen and hydrogen, and the product is ammonia. (iii) In the reaction of the catalytic oxidation of ammonia the catalyst glows red hot, Why ? In general, a chemical equation looks like this: According to the law of conservation of mass, when a chemical reaction occurs, the mass of the products should be equal to the mass of the reactants. (v) State the property illustrated in the above reaction (iii). (ii) Ammonia from nitrogen. The reaction shown is a combustion reaction: a compound reacts with oxygen and produces carbon dioxide and water. 26. (iii) Name the catalyst used. (ii) Why commercial nitric acid is brown ? (ii) Tetrammine copper (II) sulphate. Answer: This is because ammonium nitrate on heating decomposes explosively with the formation of nitrous oxide and water. 14. (ii) A compound X is dissolved in the ammonia solution to give a deep blue coloured solution, write the name of the compound having deep blue colours ? Catalytic oxidationof ammmonia. Dilute hydrochloric acid and dilute nitric acid. Answer: To the nitrate solution, add freshly prepared iron (II) sulphate solution. When ammoniacal liquor is boiled with milk of lime, the ammonia formed is passed into ice or cold water to form liquor ammonia. (viii) In ammonia molecule there is one lone pair of electrons available on nitrogen atom. Question 16: Nitric acid stains the skin yellow. (i) The burning metal which combines directly with nitrogen. Earn Transferable Credit & Get your Degree. It emulsifies fats, grease, etc. K2SO_4 4. (v) How is the temperature maintained in the Ostwald’s process ? So, the gases that are to be used should be pure and dry. Ammonia can be obtained from it by boiling. (v) Ammonia is a reducing agent. Why ? Copper and concentrated nitric acid. (ii) Name the gas evolved B. No change will be observed with hydroxide ion. Ammonia with excess chlorine. (iv) During laboratory preparation how is ammonia dried and collected ? The number of atoms of the reactants and products need to be balanced. Brown ring is due to the formation of nitrosonium pentaqua iron (I) sulphate [Fe+ (NO+) (H2O)5] SO4, which is an octahedral complex compound. 23. 4NH 3 + 3O 2 2N 2 + 6H 2 O (ii) Ammonia, when reacts with oxygen in presence of platinum (as catalyst) at 800°C, ammonia is oxidised to nitric oxide (NO). (iv) What is the name of the industrial process, which starts with the reaction of catalytic oxidation of ammonia. Answer: (i) A-Conc. - Definition & Effects, Decomposition Reaction: Definition & Examples, Double Displacement Reaction: Definition & Examples, Single-Displacement Reaction: Definition & Examples, Reactant in Chemistry: Definition & Examples, Limiting Reactants & Calculating Excess Reactants, Molar Volume: Using Avogadro's Law to Calculate the Quantity or Volume of a Gas, Balanced Chemical Equation for Photosynthesis, Combustion Reaction: Definition & Examples, Gas Evolution Reactions: Definition & Examples, FTCE Physics 6-12 (032): Test Practice & Study Guide, UExcel Anatomy & Physiology: Study Guide & Test Prep, Introduction to Natural Sciences: Certificate Program, GACE Science Test I (024): Practice & Study Guide, ILTS Science - Chemistry (106): Test Practice and Study Guide, ILTS Science - Earth and Space Science (108): Test Practice and Study Guide, TExES Health EC-12 (157): Practice & Study Guide, SAT Subject Test Biology: Practice and Study Guide, Introduction to Biology: Certificate Program, Create an account to start this course today. 4. Limiting reagent is the reactant which limits the progress of a chemical reaction. When jar is full of gas litmus will turn blue. (b) A better catalyst is ferric oxide (Fe2O3) containing 1% of potassium oxide (K2O) and 3% of aluminium oxide (Al2O3) which acts as promoters. (b) Nitrogen. Filter off the precipitate if formed. Answer: This is because of the formation of reddish brown layer of iron oxide which prevents its further reaction with the acid. This time, we put a coefficient of 3 in front of H2 to balance the chemical equation. Answer: (i) (a) Ammonium nitrate, NH4NO3 (b) Ammonia. Give the reason. {{courseNav.course.mDynamicIntFields.lessonCount}} lessons So now we look at the hydrogen (H) atoms. Answer: The heat produced by burning of magnesium is quite sufficient to decompose nitric oxide into nitrogen and oxygen. To do this, we need to put a coefficient of 2 in front Fe2O3 and a coefficient of 3 in front of CO2. Question 2: The diagram shows an experimental set up for the laboratory preparation of a pungent smelling gas. (c) Name a simple method you would employ to prepare ammonium salts in your laboratory. Thus, nitric acid can be prepared by the catalytic oxidation of ammonia. (c) It turns phenolphthalein solution pink. (d) Write the equation for conversion of F and G. (iv) Name the coloured gas and the colourless gas. (iii) The concentrated nitric acid produces yellow stains and blisters on skin. In the chemical equation, to make the number of nitrogen (N) atoms equal on both sides, first, we place a coefficient of 2 in front of NH3. There are 2 nitrogen (N) atoms and 6 hydrogen (H) atoms on both the reactants and products side. Mention the catalyst used. HNO3 on Iodine. Now that the Fe atoms are balanced, we can balance the carbon atoms. Question 10: During the manufacture of nitric acid by Ostwald’s process excess of oxygen is taken. Question 14: (i) Give the balanced equations for laboratory preparation of nitric acid and describe the reaction. (v) In the Ostwald’s process, the catalytic oxidation of ammonia to nitric oxide is an exothermic reaction. (ii) Copper reacts with hot and concentrated nitric acid to form copper nitrate, water and nitrogen dioxide.gas, which has reddish brown fumes and a pungent smell is liberated.
