Answer
Forests provide us with oxygen. They protect soil and provide habitat to a large number of animals. Forests help in bringing good rainfall in neighbouring areas. They are a source of medicinal plants, timber and many other useful products. By the process of transpiration and photosynthesis, forests maintain the temperature. Forests provide shelter for the animals and act as a protective camouflage. Forests provide shelter and food to the tribes living in the jungle. Forest trees such as the bamboo are used in making furniture, baskets, ladders, etc. The teak tree is used to make furniture. The Neem tree is used for medicinal purposes. Forests also provide wood to make paper and other products such as gum, wax, rubber, and honey. Forest influence climate, water cycle and air quality. Forests play a very important role in the food chain. When forests are affected, they affect living beings such as animals and plants.

A student is conducting an experiment to observe the reaction of magnesium ribbon when it is burned in air. The student first cleans a small piece of magnesium ribbon using sandpaper and then ignites it using a flame. The ribbon burns with a dazzling white flame, and a white powdery substance is formed after the reaction. The student records these observations and continues to investigate the nature of the product formed by adding a small amount of water to the white powder.
Q.1. What is the white powder formed after burning magnesium ribbon?
(a) Magnesium sulphate
(b) Magnesium oxide
(c) Magnesium hydroxide
(d) Magnesium carbonate
Q.2. Which of the following will most likely happen after magnesium ribbon burns?

(b) The product will turn red litmus paper blue
(c) The product will have no effect on litmus paper
(d) The product will blue litmus paper red as well as red litmus paper blue
Q.3. What is the result of adding water to magnesium oxide?
(a) It forms an acidic solution
(b) It forms a basic solution
(c) It forms a neutral solution
(d) It does not react with water
