Question

give reasons for the following in about 40-50 words
1)melamine is used for making floor tiles, kitchenware etc.
2)sodium and potassium are stored in kerosene​

Answer 1

Answer:

((1))

Melamine is used for making kitchenware etc because it can tolerate heat better than any other substances. Basically melamine is a Thermosetting plastic which does not melt by fire. Once it is melted, it cannot be melted again.

((2))

sodium and potassium kept in kerosene because Na and K are very reactive metals and kept in kerosene oil to prevent it from coming in contact with oxygen and moisture as they react to form their hydroxides.

I hope it helps ^^
