Hydrochloric acid and sodium hydroxide are mixed together to form salt and water. during the reaction, the temperature of the solution increases. which of these best explains why this is considered to be a chemical change? no energy was destroyed. heat was given off. it involved liquids. new substances formed.

The option "New substances formed" best explains why this is considered a chemical change.

Explanation:

A chemical change is a process in which one or several substances, called reagents, undergo modification of their molecular structures and are transformed into other substances, called products.

On the other side, a neutralization reaction is one in which an acid (or an acid oxide) reacts with a base (or basic oxide). In the reaction a salt is formed and in most cases water is formed. A salt is an ionic compound formed by the union of ions and cations through ionic bonds.

So:

acid + base ⇒ salt + water

Neutralization reactions are generally exothermic, which means they release energy in the form of heat.

In this case, hydrochloric acid and sodium hydroxide are mixed together to form salt and water.  Then it is a neutralization reaction, producing a chemical change that releases energy. In this way, during the reaction, the temperature of the solution increases.

So, the option "New substances formed" best explains why this is considered a chemical change.

hail is a solid form of precipitation composed of large, layered ice particles called pellets that often have spherical shapes. this phenomenon occurs during thunderstorms in the could type known as cumulus

hope this you out ^w^

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
