Elemental sulfur (S8) reacts with oxygen to form sulfur dioxide, a poisonous gas that can be used as a food additive to sterilize dried fruit and wine. Carbon burns in oxygen to form carbon monoxide and carbon dioxide gases. Elemental phosphorus (P4 82 2 222
Magnesium oxide (MgO) is a compound which is formed when oxygen (a gas & non-metal) from the air reacts with magnesium (a metal) to form a white powder known as magnesium oxide, a non-metal.
Measure the length of and empty gas jar M 1 . Place a candle stick on a petri dish. Float it on water in basin/trough. Cover it with the gas jar. Mark the level of the water in th
(b) A piece of sodium metal is added to absolute ethanol to form sodium ethoxide and hydrogen gas. Answer: 2Na + 2C 2 H 5 OH ⇨ 2C 2 H 5 ONa + H 2 (c) Iron (III) oxide on heating with carbon monoxide gas reacts to form solid iron and liberates carbon dioxide gas.
WATER Pure water is a colourless , odorless , tasteless , neutral liquid. Pure water does not exist in nature but naturally in varying degree of purity. The main sources of water include rain, springs, borehole, lakes, seas and oceans: Water is generally used for the
Calcium has a silvery color metal, which is harder than sodium, and softer than aluminium. It is less chemically reactive than the alkaline and other alkaline-earth metals. It readily forms a white coating of nitride in air, which protects it from further corrosion, and it burns in air with a yellow-red flame.
The metal reacts slowly with oxygen, water vapor, and nitrogen of the air to form a yellow coating of the oxide, hydroxide, and nitride. It burns in air or pure oxygen to form the oxide and reacts rapidly with warm water to produce hydrogen gas and calcium hydroxide.
Iron burns in oxygen to form iron (III) oxide. How many moles of oxygen gas, O 2, are needed to produce 2.56 moles of iron (III) oxide? 4 Fe (s) + 3 O 2 (g) → 2 Fe 2 O 3 (s) 2) Phosphorus trichloride forms when white phosphorus reacts with chlorine. A sample of PCl 3 was collected from a reaction of 77.25 g of P 4 with 100g of chlorine.
This occurs when the white form is exposed, but not the red form. Phosphorus is commonly used in fertilizers, to replace vital vitamins that are removed naturally from soils by plants.Oxygen Oxygen has the atomic nuer 8, and is a non-metallic element that forms oxides with most other elements.
2013/1/16· or a metal carbonate. Insoluble salts can be made by using a precipitation reaction. (a) Complete the table to show which acid or metal compound is used to make each salt listed. For each metal compound, state whether it would be used as a solid or in (5)
Pure oxygen is a clear gas which is colourless, odourless, tasteless and slightly heavier than air. One cubic metre of oxygen at 20°C and atmospheric pressure weighs 1-33 kg. Under normal pressure it liquifies at a temperature of -182-9°C forming a clear, bluish liquid.
