Balanced Chemical Equation – Solution
CaCl2 + Na2SO4 → CaSO4 + 2NaCl
The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. New substances are formed as a result of the rearrangement of the original atoms. As a result of a chemical reaction, atoms of chemical elements do not disappear anywhere and new ones do not appear, their number remains unchanged – this follows from the law of conservation of mass of substances.
Chemical Reaction Information
This is a precipitation reaction: CaSO4 is the formed precipitate.
Calcium Chloride + Sodium Sulfate = Anhydrite + Sodium Chloride
Double Displacement (Metathesis)
Substances that react are called starting materials or reactants. The substances that form as a result are called reaction products.
