Final answer:
The balanced chemical equation for the decomposition of strontium hydroxide is a) Sr(OH)₂ → SrO + H₂O.
Step-by-step explanation:
The balanced chemical equation for the decomposition of strontium hydroxide is a) Sr(OH)₂ → SrO + H₂O.
When strontium hydroxide decomposes, it forms strontium oxide (SrO) and water (H₂O). The equation is balanced because the number of atoms of each element is the same on both sides of the equation.
