This content is not included in CAPS (as part of the Grade 9 Matter and Materials requirements). A) with hydrogen. Important note: This is not required by CAPS but is offered as enrichment. The purpose of the candle shown in the picture is to set the hydrogen gas alight, in other words: to provide enough energy for the reaction to start. Copper + Water + Carbon Dioxide + Oxygen Your teacher will not demonstrate this reaction, because the sulfur dioxide that forms is a poisonous gas that you and your classmates should not be exposed to. Draw a picture equation for the reaction, using the example of carbon above as guide. Challenge question: How many bonds were broken and how many bonds were formed during this reaction? Where do we find non-metals on the Periodic Table? In the following activity we are going to review word equations, picture equations and chemical equations, using the reaction between sulfur and oxygen as our context. What happens when a non-metal and oxygen react? For each of the following reactions, complete the tables by providing the missing equations. Carbon and sulfur both form dioxides with oxygen, but this is not true of all non-metals. Here is a hint: What does the di- in dioxide mean? In this chapter we learnt about some of the reactions between non-metals and oxygen. Here are two examples for the non-metals carbon and sulfur. The common name is water and the systematic name is dihydrogen monoxide. Hydrogen and oxygen also react spectacularly. He provides courses for Maths and Science at Teachoo. calcium when added to water gives calcium hydroxide. Metals can react with water, acid and oxygen. The metallic oxides formed are basic in nature and turn red litmus solution blue. Non-metal oxides have different chemical properties to metal oxides. There are 2 phosphorus and 5 oxygen atoms. Why do you say so? Phosphorus is a very reactive non-metal element.If phosphorus is kept open in air,it react with the oxygen of air and catches fire.So,in order to protect phosphorus from atmospheric air,it is stored in a bottle containing water. (S) It is a very reactive element. Fill in the missing words in these sentences. The general equation for this reaction is: metal + oxygen → metal oxide. As a result, it catches fire if left in open. The definition of an oxidation reaction is broader and includes other reactions which you will learn about in Gr. Reactions of alkali metals with oxygen When the alkali metals are cut, they initially appear shiny grey but quickly become dull and white as they react with oxygen in the air. http://www.flickr.com/photos/cote/66570391/, http://www.flickr.com/photos/thure/2549381513/, https://en.wikipedia.org/wiki/File:Sulfur-sample.jpg, http://www.flickr.com/photos/borderlys/4986300585/, http://www.boston.com/bigpicture/2010/12/kawah_ijen_by_night.html, http://www.flickr.com/photos/itineranttightwad/3694711587/, http://www.flickr.com/photos/indyplanets/3397279830/, http://www.flickr.com/photos/27663074@N07/3415792966/. See if you can write down the formula for sulfur dioxide before we carry on. The energy in these energy sources comes from the energy stored in plants and other living organisms that were fossilised over millions of years. Coal, oil and natural gas are examples of non-renewable fuels. It is, therefore, kept immersed in kerosene. Metal + Oxygen → Metal Oxide 4K + … When a non-metal burns in oxygen, a non-metal oxide forms as product. The question has been included in an attempt to create some relevance. - Oxygen is a very reactive non metal. What is the systematic name of the product of this reaction? The topic of chemical reactions is an abstract one and it often helps to provide some real-world applications to link it to other, less abstract including learners' own experience. Metal oxides are basic in nature.They turn red litmus to blue. Metal + Oxygen Reaction of Copper with Moist air It turns red litmus paper blue Non-Metal Oxide When a metal reacts with oxygen, a metal oxide forms. Metals react with Oxygen to produce metal oxide. To write the formula, you may need to guide learners to realise there are 2 oxygen atoms in one molecule of sulfur dioxide: SO2. 2. The general equation for this reaction is: metal + oxygen → metal oxide. * Most non metals burn in Oxygen/air to … In very small quantities SO2 does not permanently harm a large organism such as a human being, but bacteria cannot survive when it is present. Is it balanced? The picture equation for the reaction is shown below. Sulphur + Oxygen 2 H2 + O2 → 2 H2O. Except where otherwise noted, this site is covered by a closed copyright license. (Fe2O3) (O2) Oxygen is all around us in the air we breathe. What is the common name of the product of this reaction? Saloni took a piece of burning charcoal and collected the gas evolved in a test tube. When phosphorus reacts with oxygen the chemical equation for the reaction is the following: How many phosphorus atoms are in P2O5? Complete Reaction of Non Metals with Oxygen- Materials : Metals & Non-Metals Class 8 Video | EduRev chapter (including extra questions, long questions, short questions) can be found on EduRev, you can check out Class 8 lecture & lessons summary in the same course for Class 8 Syllabus. We use this information to present the correct curriculum and Write a short paragraph (3 or more sentences) to explain what you understand each of the following terms to mean, in your own words. Substances that are not reactive are called unreactive or inert. Magnesium + Oxygen Metals react with oxygen to form metal oxides. The non-metal and oxygen gas (O2) are the reactants in this type of reaction, and a non-metal oxide is the product. The reaction of hydrogen with oxygen (video). - Burning/combustion is the reaction of Oxygen with an element/substances. The reactions of carbon and sulfur with oxygen are examples of non-metals reacting with oxygen. react with oxygen to make metal oxides. Metals donate electrons to oxygen for the formation of metal oxides. B) with oxygen Non Metals react with oxygen to Produce Non Metal Oxide. On signing up you are confirming that you have read and agree to Iron Oxide (If you are unsure how to name it, sneak a peek at the first chapter!). (CO2) The systematic name of any given compound should be unique so that the compound cannot be confused with any other compound. We think you are located in An important chemical difference between metal and non-metal oxides is that when metal oxides dissolve in water, they form basic solutions and when non-metal oxides dissolve in water, they form acidic solution. If learners do not have coloured pens or pencils, they can use patterns and shading to differentiate between different atoms. A substance that will react readily with many other substances is called a ____________ substance. Our final example is a compound that you should be very familiar with! Homework •Worksheet acid rain •Act 3.3 p.73 •Revision activity 6 p. 74. Write its name and formula. You can also get learners to construct the equation by using sheets of white paper and drawing a '+' and '$$\rightarrow{}$$. Non-metals:Non-metals like carbon, sulphur, and phosphorus react with oxygen to form non-metallic oxides. Thus,Phosphorus is kept in water containers Questions Sulfur burns in oxygen to form sulfur dioxide. (Mg) Reaction of Non-Metals with Oxygen Non Metals react with oxygen to Produce Non Metal Oxide It is acidic in nature Example Note- Why is Phosphorus not kept in open? The energy released by burning coal is used to generate electrical energy in coal-powered power stations. Example Metal Oxide (Cu (OH)2) You may want to ask if water (H2O) is a non-metal oxide. Colours are not important as long as all atoms of the same element have the same colour. The energy in coal comes from the energy stored in plants and other organisms that lived hundreds of millions of years ago. Let's look at a few specific examples of reactions in which non-metals react with oxygen. Get learners to discuss this for a moment. Metal react with oxygen to form metal Oxide. 1 bond was broken (between the oxygen atoms) and 2 bonds were formed (1 between each of the oxygen atoms and the sulfur atom). (O2) For example, 4K + O 2 → 2 K 2 O Metal oxides are generally basic in nature but it can also be amphoteric in nature. Davneet Singh is a graduate from Indian Institute of Technology, Kanpur. Video Acid rain Acid Rain Eating Washington, D.C..mp4. Complete the concept map below. Provide play dough or modelling clay for this part of the activity. The heat and pressure from the top layers caused the plant remains to turn into energy-rich coal. This is Acidic in nature Write the product where it belongs. Some metals like sodium and potassium react vigorously with oxygen. Coal is a form of carbon and when it burns in oxygen we can represent the reaction with the following word equation: Draw a picture equation for this reaction in the space below. In the next section, we are going to look at the formation of another, less well-known, non-metal oxide named sulfur dioxide. When an element is reactive, it means that it will readily react with many other substances. Oxygen also forms covalent oxides with non-metals, that react with water to form acidic solutions. S19), the galvanostatic charge-discharge test was used to examine the rechargeable ZAB with current of 10 mA/cm 2. [3 x 3 = 9 marks]. w/s3. CO2 and SO2), one should be mindful of the possible introduction of a misconception in this regard. Here is a diagram to show what is really happening to the compounds in this reaction. Chemists have evidence that the actual shape of the SO2 molecule is not linear; in other words, the atoms do not all lie in a straight line as they do in CO2. Amphoteric oxides mean that they are acidic as well as basic in nature. Early chemists used the term oxidation for all reactions in which oxygen was a reactant. (CuCO3) Thus,Phosphorus is kept in water containers. Air with Moisture Some of the skills that we practised during this chapter were: writing equations (word, picture and chemical equations) and naming compounds. These reactions are called combustion reactions. … Can you write a word equation for this reaction? Do all non-metals form non-metal dioxides when they react with oxygen? The formation of metal oxide is a redox reaction. Reactions with Hydrogen. For example, magnesium burns rapidly in air: Magnesium + oyxgen → magnesium oxide. Sulphur–Non-metal—does not react with water. The first one is one that you are already familiar with, namely the reaction of carbon and oxygen. You wrote the word equation for the reaction between sulfur and oxygen above. 2Mg(s) + O 2 (g) → 2MgO(s). Two examples of combustion reactions are: Iron reacts with oxygen to form iron oxide: 4 Fe + 3 O 2 → 2 Fe 2 O 3 The archaic (very old) name for sulfur is 'brimstone'. Corrosion reactions are generally very slow, whereas combustion reactions are very fast and produce large amounts of heat and light. Corrosion and combustion are two examples of oxidation reactions. We have looked at two examples of non-metals reacting with oxygen to form non-metal oxides. Use play dough or clay to build models of the reactants and products of the reaction. No, because it contains only one oxygen. Can you think of the names of some alternative, renewable energy sources? (MgO) There are no demonstrations prescribed by CAPS for this chapter, but we have included colourful photographs to provide learners with some experience of the splendour of these reactions. Since coal is a non-renewable energy source as well as one that causes pollution and other environmental problems, scientists and engineers continue to look for alternative fuels and energy sources to eventually replace coal as an energy source.
