Water boils to produce steam at 100\u00b0C (212\u00b0F):<\/strong> This is a physical change, not a chemical reaction. Boiling is a phase change where water turns from liquid to gas (steam) without altering its chemical composition.<\/li>\n\n\n\n<li><strong>B. Water dissolves sugar:<\/strong> This is a physical change, not a chemical reaction. Dissolving sugar in water involves a physical process where sugar molecules become dispersed in water but do not change chemically.<\/li>\n\n\n\n<li><strong>C. Water produces gas with sodium metal:<\/strong> This is a chemical reaction. When water reacts with sodium metal, it produces sodium hydroxide (NaOH) and hydrogen gas (H\u2082). The reaction is:2Na+2H2O\u21922NaOH+H22 \\text{Na} + 2 \\text{H}_2\\text{O} \\rightarrow 2 \\text{NaOH} + \\text{H}_22Na+2H2\u200bO\u21922NaOH+H2\u200bThis reaction involves a change in chemical composition, making it a chemical reaction.<\/li>\n\n\n\n<li><strong>D.
