Yes, it is true, a product is formed..
Gas
cell membrane
The reactants and the products must contain the same numbers of the same types of atoms, that is, atoms with the same atomic number, and either the products must contain at least one type of chemical bond distinct from any chemical bond in the reactants or the reactants must contain at least one type of chemical bond not found in the products.
A change in the amount (or concentration) of at least one of the reactants and products or a change in temperature or pressure.
The products of a chemical reaction have different properties than the reactant because they underwent a chemical change by definition of a chemical reaction. The products are new combinations atoms forming different molecules.
Reactants are on the left side, at least in languages read from left to right.
At least 2 of the reactants must change their chemical formula.

No. A material is heated, i.e. changes state, then hardens again. No chemical change, but at least a partial state change.
In any chemical reaction, at least one chemical bond is either broken or formed. However, particularly in organic chemical reactions, many bonds may remain intact from the reactants to the products, provided that at least one is broken or formed.
The least reliable indicator of a chemical change is shape. Change of shape usually indicates a physical change, unless the material change resulted from a recombination or decomposition of the material's chemical form, as in the rotting of vegetable matter.

At least one change in chemical bonding.
Almost any chemical element or compound can participate in some type of chemical reaction and thereby be a reactant. One of the more common reactants is oxygen. It may be that only helium can never be a reactant.
They are on the left side of the equation with an arrow pointing to the substances being formed on the right side of the equation (the products).
Lowers the activation energy of a reaction, therefore speeding the reaction up.Catalysts speed up chemical reactions. They do not change the products or reactants of the reaction, and are not used up or consumed in the reaction. Biological catalysts are called enzymes. Catalysts lower the activation energy (or energy needed to start a reaction), and cause the reaction to occur more quickly.
