Give an example of a chemical or physical process that illustrates the law of conservation of mass?
Every time you balance a chemical equation, you uphold the law of conservation of mass, which says that matter cannot be created nor destroyed. Take a basic balanced chemical equation: 2Na + Cl2 --> 2NaCl. That's the synthesis of salt from its constituent elements sodium and chlorine. Looking at the Periodic Table, the Atomic Mass of sodium is 23 and chlorine is 35. Two moles of sodium is 46, and diatomic chlorine is 70. That adds up to 116. Now look at salt. One sodium and one chlorine add up to 58. Double it because your molar coefficient is 2, and you get 116. 116=116, so this once again proves the law true.

Is malleability an example of physical properties or chemical properties?
Malleability is an example of a physical property. It refers to the ability of a material to be reshaped without breaking. Chemical properties, on the other hand, describe how a substance interacts with other substances in chemical reactions.
Is a phase change an example of a physical or chemical or nuclear or a covalent change?
A phase change is an example of a physical change, not a chemical, nuclear, or covalent change. During a phase change, the substance undergoes a change in state (solid, liquid, gas) without any change in its chemical composition.
