Answers
Answer:
When an ethnol is burnt in air it reacts with oxygen and produces carbon dioxide water vapour and heat
Explanation:
Pure enthol is flammable colourless liquid with boiling point of 78.5 degree cellulose its low melting point of - 114.5 degree cellulose allows it be used in antifreeze products
(A).C2H5OH
(B). when ethanol is wanting a it burns with Aafrin give carbon dioxide and water are formed stop in this reaction, release of large amount of heat and light takes place.
Methane. Oxygen Carbon dioxide 2H2O(g)+Heat and Light.
(C). first ethanol is a colourless liquid and it is soluble in water equal proportions in Hafiz in order. second the boiling point of Ethanol is 78° C and the freezing point is -1 14 ° C. and once with a blue flame. forth in aqueous solution of Ethanol is neutral to Litmus Paper.
