Metals

good conductors of heat and electricity.

mostly solid at room temperature.

they can be solids ,liquids and gaseous at room temperature..

they are flexible and can be drawn into wires

Non-metals

they are brittle and break into sharp pieces.

poor conductors of heat and electricity.

Good conductors of heat and electricity - Metal

Brittle and break - Nonmetal

Flexible - Metal

Mostly solids at room temp. - Metal

Poor conductors of heat and electricity - Nonmetal

Solids, liquids, or gasses at room temperature - Nonmetal

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

i'm pretty sure its b i might be wrong though!
