A chemical change involves a rearrangement of atoms to form new substances with different chemical properties, while a change of state is a physical change where a substance transitions between its solid, liquid, or gas state without changing its chemical composition.

No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.

A physical reaction is were the current substance can be changed in state and then changed back easily to it's previous state, a chemical reaction is the opposite, it is difficult to change it back to its previous state.

Element oxidation state is a chemical property, as it is related to the number of electrons an atom gains, loses, or shares when forming chemical bonds with other atoms. It reflects an element's ability to undergo chemical reactions.

When a chemical is in an aqueous state, it means that it is dissolved in water. This allows the chemical to interact with water molecules, forming a homogeneous solution. The presence of water can affect the physical and chemical properties of the compound.

A physical state is physical and not chemical
Physical Property is observed without changing a substance into another substance.
Chemical property is the ability of a substance to change into different substance.

not always, like the change is in the display without change in composition then it is change of state, other then will be chemical change

1 answer
State symbols in chemical equations are used to indicate the physical state of the substances involved (solid, liquid, gas, or aqueous solution). This information is important because the physical state can affect the reaction conditions and the behavior of the substances in the reaction. Including state symbols provides a more complete and accurate representation of the chemical reaction.
1 answer
State symbols in a chemical equation indicate the physical state of the reactants and products. Common state symbols include (s) for solid, (l) for liquid, (g) for gas, and (aq) for aqueous (dissolved in water).
