Chapter covers the topics like What is 10th ncert chemical reactions and equations answers on reaction? What happens when dilute hydrochloric acid is added to iron fillings? Tick the correct answer. Answer: Reaction between dilute hydrochloric acid and iron filling equattions given by �. What is a balanced chemical equation? Why equationw chemical equations be balanced? Answer: Balanced chemical equation is a chemical reaction in which atoms in the reaction are balanced on both the sides.
As per the law of conservation of mass, mass can neither be created nor be destroyed. Therefore, mass of atoms in reactant and products should be equal. This, suggest that total number of atoms of each reactiosn on both sides of the reaction should be. However, all reaction should obey the law, therefore, it is necessary chemica, balance the reaction. Translate the following statements into chemical equations and then balance.
Write the balanced chemical equation for the following and identify the type of reaction in each case. Answer: When energy is released during the reaction, it is said to be exothermic reaction. Examples of exothermic reaction are explosions, nuclear reactions.
When energy is absorbed during the reaction, it is said to be endothermic reaction. Examples of endothermic reaction are evaporation, melting of ice. Answer: Living organisms acquire reactiohs from food.
During the process of digestion, complex substance in the food is broken down into glucose i. In the cell, glucose combines with oxygen to generate energy. This occurs during respiration. As energy is released therefore, respiration is known as exothermic reaction.
Why are decomposition reactions called the opposite of combination reactions? Write equations for these reactions. Answer: In decomposition reaction, a compound breaks into two or more substances. These reactions proceeds by acquiring energy. In combination reaction, two or more substances combines to form a compound, thereby releasing the energy. Thus, decomposition reactions are called opposite reactions of the combination reaction.
The general form of decomposition and combination reaction is given by. Write one equation each for decomposition reactions where energy is supplied in the form of heat, light or electricity. What is the difference between displacement and double displacement reactions?
In the refining of silver, the recovery of silver from silver nitrate solution involved displacement by copper metal. Write down the reaction involved. Answer: Reaction in which precipitate is formed, which is an insoluble substance. Such reaction is called precipitate reaction. Explain the following in terms of gain or loss of oxygen with two examples. Answer: Shiny brown coloured element X is copper and black colour substance is copper oxide CuO.
Following is the reaction forming copper oxide from copper �. Answer: Paint ncerf applied on iron articles as, it acts as a protective layer and prevent iron from rusting. Paint cuts the contact of air and moisture from iron and therefore, rusting of iron is prevented. Answer: Nitrogen gas does not reacts easily with other substance.
Oxygen reacts with food materials containing oils and fats and rdactions them rancid. Bags used in packing such food materials in flushed with nitrogen in order to remove reacgions from it and since nitrogen does not react with food materials, it prevent food materials from getting rancid. Explain the following terms with one example.
Answer: a Corrosion � Corrosion is defined as process in which materials loses their strength and quality due to chemical reactions with moisture, air. Hydrated iron oxide or rust. Example : Change in odour and taste of butter or oil takes place, when used after a long period of time.

Which of the statements about the reaction below are incorrect?
Answer: d displacement reaction. Balance the following chemical equations. Write the balanced chemical equations for the following reactions. What does one mean by exothermic and endothermic reactions? Give examples. Why is respiration considered an exothermic reaction? Answer: Displacement Reaction Double Displacement Reaction In this reaction more reactive element 10th ncert chemical reactions and equations answers on less reactive element in a compound.
In this reactions, atoms or group of atoms interchange their places to form a new compound. What do you mean by a precipitation reaction? Explain by giving examples. Why do we apply paint on iron articles? Oil and fat containing food items are flushed with nitrogen.
Example : Rusting of iron in presence of moisture and air. CBSE Class Rated 4. Rated 5. Not recently active.
