Question 1: What is meant by a skeletal chemical equation? Using suitable chemical reaction, differentiate between a skeletal chemical equation and a balanced chemical equation. Answer 1: If the number of atoms of any element in a chemical equation is not equal on both sides, then it is a skeletal equation.

For example:. Here, the number of chlorine and hydrogen atoms are not equal on both sides. In a Balance equation, the numbers of atoms of different elements on both sides of a chemical equation are equal.

Question 2: Explain the following terms with examples in each case: i Oxidation and ii Reduction. Answer 2: i Oxidation: it us a process a in which oxygen or any electronegative element is added up or b hydrogen or any electropositive element is removed. Examples are: a Sulphur burns in the air with a blue flame to form sulphur dioxide. Here oxygen is added up to sulphur. Question 3: Why is respiration considered an exothermic reaction?

Answer 3: During digestion, food is broken down into simpler substances. Food like rice, potato and bread are made up of carbohydrates. These carbohydrates are further broken down into glucose. Glucose during respiration inhalation of oxygen is oxidised with the liberation of energy as shown below. Thus, respiration is an exothermic process. Examples are: a Hydrogen reacts with chlorine to form hydrogen chloride. Important Questions on 10th Science Chapter 1 What is a balanced chemical equation?

Why should chemical equations be balanced? A reaction which has an equal number of atoms of all the elements on both sides of the chemical equation is called a balanced chemical equation. The law of conservation of mass states that mass can neither be created nor destroyed. Hence, in a chemical reaction, the total mass of reactants should be equal to the total mass of the products.

It means that the total number of atoms of each element should be equal on both sides of a chemical equation. Hence, it is for this reason that chemical equations should be balanced.

Why is respiration considered an exothermic reaction? Energy in our body is obtained from the food we eat. During digestion, large molecules of food are broken down into simpler substances such as glucose. Glucose combines with oxygen in the cells and provides energy. The special name of this combustion reaction is respiration. Since energy is released in the whole process, it is an exothermic process. Why are decomposition reactions called the opposite of combination reactions? Decomposition reactions are those in which a compound breaks down into two or more substances.

These reactions require a source of energy to proceed. Thus, they are the exact opposite of combination reactions in which two or more substances combine to give a new substance with the release of energy. Why do we apply paint on iron articles?

Iron articles are painted because applying paints prevents them from rusting. When painted, the contact of iron articles from moisture and air is cut off. Hence, rusting is prevented their presence is essential for rusting to take place. Oil and fat containing food items are flushed with nitrogen. Nitrogen is an inert gas at room temperature and does not easily react with oil and fat containing items.

On the other hand, oxygen reacts with food substances and makes them rancid. Thus, bags used in packing food items are flushed with nitrogen gas to remove oxygen inside the pack. When oxygen is not present inside the pack, rancidity of oil and fat containing food items is avoided. Chapter 2: Acids, Bases and Salts �.
