Non metals are usually poor conductors of heat and electricity. They are non-lustrous, non-sonorous, non-malleable and are coloured.

In this study, a light-coloured eye is a dominant trait because children born from parents having light-coloured eyes also had light-coloured eyes.

(c) either metals or non-metals 

This element is a metal. Other characteristics expected to be possessed by the element are–lustre, malleability, heat and electrical conductivity. 

(c) Generally, metals are ductile. However, mercury metal - a liquid at room temperature - cannot be drawn into wires and is not ductile.

(a) Phosphorus is a very reactive non-metal.  (b) Metals are good conductors of heat and electricity.  (c) Iron is more reactive than copper.  (d) Metals react with acids to produce hydrogen gas.

Metallic solids are electrical conductors, malleable, and ductile. 

(a) Alloys of metals usually have greater resistivity than that of their constituent metals. (b) Alloys usually have lower temperature coefficients of resistance than pure metals. (c) The resistivity of the alloy,...

(c) Wood , Answer is correct

(D) (ii) and (iv)

(d) In gaseous state the HCl is covalent in nature while in aqueous solution it ionises to give H+ and Cl- ions
