A. Symbols telling how many atoms are in each substance
B. Symbols telling the mass of the substances
C. Symbols telling what form of matter the substances are in
D. Symbols telling how many molecules will react help plz
"C-Symbols telling what form of matter the substances are in." Four different states can exist: Gases (g), liquids (l), solids (s), and aqueous (aq) (dissolvable in water) are among them. The state symbols appear inside brackets slightly underneath the text just after the product or reactant. In every chemical equation, they should be included.
State symbols are the representations of the reactants taking part in any given reaction. The symbols are also used to represent the condition that the reactants have taken after a chemical reaction. The state symbol tells us the number of atoms in every reactant or substance, and they combine
Answer A. This gives more information about the reactants and products. For instance, when an iron nail is placed in a solution of blue copper (II) sulphate. After a while, a brown solid appeared, and solutions became colorless, so it balanced the chemical equation for the reaction of iron with copper (II) sulphate.
