Sat 2. All questions compulsory (Chemistry) Q1) Acid present in apple is: A Orlic acid B. Malic acid Acetic acid D. Formic acid Q2) Generally, when certain metals react with an acid they release gas A Nitrogen B. Oxygen Cardrogen D. Argon Q.3) Which of the given is used as an antacid? A Sodium hydrocarbonate B. Calcium hydroxide C Magnesium hydroxide DA the these Which one of the following is formed when calcium hydroxide reacts with carbon dioxide? 4 Hydrogen gas B Water C Salt D. Both Band C Q-5) Soda ash chemical formula is A NaHCO B. Na Coz. 9H20 ha.co, D. Na,coz 10H20 Q.6 When electricity passes through Nad aqueous solution A Sodium metal is deposited LB. Only Chlorine gas is produced chlorine & Hydrogen gases are produced Q.7 Vinegar is used in picking as it A is an acid B. Prevents the growth of microbes c Prevents drying of a picke D. Increases taste Q.8 Generally, non-metals are not conductors of electricity. Which of the given is a good conductor of electricity? A Diamond B. Graphite c Sulphur D. Fullerene 09 Electrical wires have a coating of an insulating material. The material generally used is A Sulphur B. Graphite CPCD. All can be used Q.10) Metals as we know, are very useful in all fields, industries in particular. Non-metals are no less in any way. Oxygen present in air is essential for breathing as well as for combustion. Non-metals form a large number of compounds which are extremely useful, e.g., ammonia, nitric acid, sulphuric acid, etc. Non- metals are found to exist in three states of matter. Only solid non- metals are expected to be hard however, they have low density and are brittle. They usually have low melting and boiling points and are D. All of the given are produced meclizo
