please solve the above question!! from 34 to 35.
Answers
Explanation:
34. i) The property of metals that allows metals to be hammered into thin sheets is called Malleability. Non-metals do not possess this property.
(ii) The property of metals which enables them to be drawn into wires is called ductility. Non-metals do not possess this property.
(iii) Metals have free electrons which makes them good conductors of heat and electricity. Non- metals do not have free electrons, hence, they are nonconductors of heat and electricity.
35.Aluminum is highly ductile and malleable. It can easily be drawn into wires and drawn into sheets
36. (a) Copper metal is used for making electric wires because it is highly ductile in nature. It is a good conductor of electricity.
(b) Graphite is made of carbon. Its valence electrons are free to move. As a result, graphite is able to conduct electricity which makes it useful for making an electrode in a cell.
37.Evaporate the colourless liquid on a low flame. If no residue is left, then it is pure water otherwise not.
38.sea water , air , soda water
39.1) air can be separated into it constitutes like oxygen, nitrogen etc. by physical process of fractional distillation. 2) error shows the properties of all the gases present in it. 3) air has variable composition
soory I can't do this I am soo soory
