Asubstance is tested in a lab it is found to maintain a unique shape and is a good conductor of electricity if is made up of electron protons and neutrons what state of matter is the substance most likely to be ?

Explanation:

It is known that a solid substance will be made up of atoms which are strongly held together. And, each atom of this solid substance consists of protons, neutrons and electrons.

Only solid substances have a fixed shape and volume.

As electricity is the flow of electrons and a solid substance is able to conduct electricity if it has free electrons available.

For example, in solid state also copper is a good conductor of heat and electricity.

Thus, we can conclude that when a substance is tested in a lab it is found to maintain a unique shape and is a good conductor of electricity if is made up of electron protons and neutrons then state of matter most likely to be solid.

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.
