Learners should have encountered the topics coal, fossil fuels, renewable and non-renewable energy sources and electricity generation in previous grades (specifically in Gr 6 and 7 Energy and Change) and they will also look at it again next term. Metals, on being burnt in air, react with the oxygen to form metal oxides. 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. We use this information to present the correct curriculum and If an element forms a basic oxide,then the element will be a metal. Provide play dough or modelling clay for this part of the activity. Draw a picture equation for the reaction, using the example of carbon above as guide. 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. The metallic oxides formed are basic in nature and turn red litmus solution blue. Where do we find non-metals on the Periodic Table? For example, oxygen reacts with solid carbon to form carbon monoxide or carbon dioxide, respectively, as shown below (reaction not balanced): The reactions of carbon and sulfur with oxygen are examples of non-metals reacting with oxygen. Coal is a form of carbon that is used as fuel for many different purposes. These reactions are called combustion reactions. Question 1 How do metal oxide differ form non-metal oxide?

Challenge question: How many bonds were broken and how many bonds were formed during this reaction? Non- metals react with oxygen to form acidic oxides or neutral oxides. Is it a dioxide? But most of the non-metals reacts with oxygen on ignition. If you're seeing this message, it means we're having trouble loading external resources on our website. All rights reserved. Compounds that are reactive will readily react with many other substances. For each of the following reactions, complete the tables by providing the missing equations. Metals:Most metals combine with oxygen to form metal oxides. Hydrogen and oxygen also react spectacularly. 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 equations follow as: Question 14. You can also get learners to practice rearranging the atoms with this equation, making sure they have a balanced equation. 1. Want to see the step-by-step answer? Write a short paragraph (3 or more sentences) to explain what you understand each of the following terms to mean, in your own words. Now, use the formulae of the reactants and products to write a chemical equation. Since the explanation for this shape requires some understanding of bonding models, which are beyond the scope of this level of the curriculum, we recommend that you do not 'go there', but accept 'linear' drawings of the SO2 molecule as correct. In this chapter we look at a few reactions of non-metals with oxygen. Our final example is a compound that you should be very familiar with! CO2 and SO2), one should be mindful of the possible introduction of a misconception in this regard. It is one of the primary fossil fuels that humans use to generate electricity for powering our industries, our activities and our living spaces. Not all non-metal oxides are dioxides, as the following examples show. 2. i) Reaction with oxygen:-Metals react with oxygen to form metal oxides. Most nonmetal oxides are acidic and form oxyacids, which in turn yield hydronium ions (H 3 O +) in aqueous solution. 10 if you continue with Physical Sciences. For example: Carbon forms an acidic oxide CO 2, sulphur forms an acidic oxide SO 2, and hydrogen forms a neutral oxide, H 2; The non-metal oxides are covalent in natures which are formed by the sharing of electrons. (If you are unsure how to name it, sneak a peek at the first chapter!). The reaction is balanced because it has the same number of S and O atoms on either side of the equation. When phosphorus reacts with oxygen the chemical equation for the reaction is the following: How many phosphorus atoms are in P2O5? The reaction of hydrogen with oxygen (video). In this chapter we learnt about some of the reactions between non-metals and oxygen. 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? 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. 4Al + 3O 2 2Al 2 O 3. Once again, the translation between word equation, picture equation and chemical equation is reinforced with exercises and examples.

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. Point out that hydrogen (H) is a non-metal and that water should be a non-metal oxide. It is, therefore, kept immersed in kerosene. 1 bond was broken (between the oxygen atoms) and 2 bonds were formed (1 between each of the oxygen atoms and the sulfur atom). Complete the concept map below. [3 x 3 = 9 marks]. C + O2 → CO2 (carbon dioxide, which is an acidic oxide) When sulfur reacts with oxygen, we get sulfur dioxide.
