Answer:
Sum of the coefficients is 3, in both sides (reactant & product)
Step-by-step explanation:
HCl and Ca(OH)₂ react in a neutralization reaction.
It is called neutralization because we can produce H₂O. It always occurs when you react an acid with a base.
The equation for this is:
2HCl + Ca(OH)₂ → CaCl₂ + 2H₂O
Sum of the coefficients is 3, in both sides (reactant & product)
