Answer:
2 lithium atoms and 2 Bromide atoms
Step-by-step 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.
