Important Question for Class 10 Science Metals and Non …
61.No reaction takes place when granules of a solid ‘A’ are mixed with a powder of solid ‘B\ However when the mixture is heated, a reaction starts with evolution of much heat. Product ‘C’ of the reaction settles down as a liquid metal and solid product ‘D’ keeps floating over the liquid ‘C\ This reaction is sometimes used for making metals for ready use in odd places.
metal - Students | Britannica Kids | Homework Help
Some metals are less reactive with water. Calcium reacts vigorously with water, though not as vigorously as sodium and potassium. A few metal-water reactions vary with the temperature of the water. For example, magnesium reacts slowly with cool water
Calcium - Compounds | Britannica
Calcium - Calcium - Compounds: The most important calcium compound is calcium carbonate, CaCO3, the major constituent of limestone, marble, chalk, oyster shells, and corals. Calcium carbonate obtained from its natural sources is used as a filler in a variety of products, such as ceramics, glass, plastics, and paint, and as a starting material for the production of calcium oxide. Synthetic

Reaction of aluminium with water Aluminium is a silvery white metal. The surface of aluminium metal is covered with a thin layer of oxide that helps protect the metal from attack by air. So, normally, aulumium metal does not react with air. If the oxide layer is
Do not use water on metal. If the spilled calcium has come into contact with water, proceed cautiously. The reaction can rapidly proceed to self-ignition of hydrogen and spattering of molten calcium. Evacuate the area, put on protective equipment and proceed as
Calcium hydride - Wikipedia
Calcium hydride is the chemical compound with the formula CaH 2, and is therefore an alkaline earth hydride.This grey powder (white if pure, which is rare) reacts vigorously with water liberating hydrogen gas. CaH 2 is thus used as a drying agent, i.e. a desiccant.

A possible extension is to hold a cold piece of metal or glass above the place where you burst the bubbles so that the water vapour that forms during the reaction condenses on the metal or glass. Place approximately 1 g of the magnesium pieces in the test tube, but do not add the hydrochloric acid until everything else is ready to be asseled.

When reaction between an acid and a metal occurs, we observe formation of gas bubbles. When these gas bubbles are passed through soap solution, gas filled soap bubbles rise into the air. When a burning candle is brought near a gas-filled soap bubble, the gas present in …
Calcium Metal - Australian Science Teachers Association
Calcium metal reacts with water to give calcium hydroxide and hydrogen gas. €Hydrogen gas is flammable, and therefore it is important to carry out this reaction in a well-ventilated area or in an operating fume cupboard.€ Slow addition of the calcium to the water will also help to
