48. Given the equation representing a reaction:
This equation represents
(1) sublimation
(2) condensation
(3) fission
(4) fusion
Solution: Sublimation is a phase change going from solid to gas phase. Condensation is a phase change going form gas to liquid. Fission is a nuclear reaction. In fission we see neutron on the left side. Fusion is a nuclear reaction with small nuclei coming together such as hydrogens coming together to form larger atoms. This reaction is fusion, choice 4
