Answer 15

two non metals

Question 16

diamonds sand and graphite

Question 17

How to measure melting points

Answer 17

small capillary tube, attaching this to the stem of a thermometer centred in a heating bath, heating the bath slowly, and observing the temperatures at which melting begins and is complete.

Question 18

How to find solubilty

Answer 18

Add a small amount of the solute to the water and stir with a clean disposable spoon until dissolved

Question 19

how to mesure conductivity

Answer 19

with a probe and a meter. Voltage is applied between two electrodes in a probe immersed in the sample water. The drop in voltage caused by the resistance of the water is used to calculate the conductivity per centimeter.
