What type of matter is in this sign, making it light up?
A. Solid
B. Liquid
C. Plasma

C. Plasma

Explanation:

Plasma is a state of matter that is similar to gas, but typically at a higher temperature. The primary difference between a plasma and a gas is that plasma is a mixture of electrons and positively charged gas ions. The electrons come from collisions between the gas particles; the collisions are so strong that they cause electrons to break free of the gas particles.

Most lighted signs have some kind of gas inside of them, such as neon. These signs are connected to an electrical plug or a battery. When the sign is switched to "on," an electrical current will move through the gas, causing it to become plasma.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
