Chapter 1 Chemical Reactions and Equations Q.1. Why should magnesium ribbon be cleaned before burning in air ? Ans: Magnesium ribbon is a very reactive metal. When stored it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide being a stable compound prevents further reaction of magnesium with oxygen. The magnesium is cleaned before burning in air to remove this layer so that the metal can be exposed to air properly. Q.2. Write the balanced

This symbol reminds those handling the package to keep out of the rain and not to store it in damp conditions. It is normally found on card based packages which would be damaged if placed in contact with water. The broken wine glass suggests that the product inside the packaging could be easily damaged if dropped or handled without care and attention. The contents are fragile! The two hands holding or protecting the package is another reminder that the contents should be handled with care

First‚ measure the length‚ L‚ of the rod using a meter stick and make an estimate of the uncertainty in the length and call this number all. Next‚ insert the rod into the aluminium jacket and put it in place on the supporting apparatus. It is very important that the rod is properly placed. One end must be firmly pressed against the screw protruding from the supporting apparatus‚ while the

Solder (/ˈsoʊldə/‚[1] /ˈsɒldə/[1] or in USA /ˈsɒdər/[2]) is a fusible metal alloy used to join together metal workpieces and having a melting point below that of the workpiece(s). Soft solder is typically thought of when solder or soldering is mentioned‚ with a typical melting range of 90 to 450 °C (190 to 840 °F).[3] It is commonly used in electronics‚ plumbing‚ and assembly of sheet metal parts. Manual soldering uses a soldering iron or soldering gun.Alloys that melt between 180 and 190 °C (360

JSUNIL TUTORIAL ‚ SAMASTIPUR‚ BIHAR IX CBSE CHAPTR - ATOMS AND MOLECULES The word atom is derived from the Greek word “Atomos” which means indivisible. John Dalton modelled atoms as hard indivisible spheres. An Indian philosopher Maharishi Kanad‚ postulated that if we go on dividing matter (padarth)‚ we shall get smaller and smaller particles. Ultimately‚ a time will come when we shall come across the smallest particles beyond which further division will not be possible. He named these particles
