Answer:

2 lithium atoms and 2 Bromide atoms

Explanation:

  • The complete equation for the reaction is;

CaBr₂ + 2Li → Ca + 2LiBr

  • It is an example of a displacement reaction where a reactive metal displaces a less reactive metal from its compound.
  • According to the law of conservation of mass, the mass of reactants should be equal to the mass of the reactants.
  • The law of conservation of mass is achieved by balancing an equation to make sure the number of atoms is equal on either side of the equation.
  • In our case, the blank will have 2 lithium atoms, 2 Bromine atoms to demonstrate the law of conservation of mass.
