<span>1. Gaseous acetylene (C2H2) reacts with oxygen gas to form gaseous carbon dioxide and gaseous water.
2. Chlorine gas reacts with aqueous potassium iodide to form solid iodine and aqueous potassium chloride.
3. Solid lithium oxide reacts with liquid water to form aqueous lithium hydroxide.
4. Gaseous carbon monoxide reacts with oxygen gas to form carbon dioxide gas.</span>
There are several differences between<span> a </span>physical and chemical change<span> in matter or substances. A </span>physical change<span> in a substance doesn't </span>change<span> what the substance is. In a </span>chemical change<span> where there is a </span>chemical<span> reaction, a new substance is formed and energy is either given off or absorbed.</span>
