xt{H}_8 + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O} \] Answer: Step 1: Count atoms on both sides. Step 2: Balance carbon atoms: 3 on reactant side, so produce 3 CO₂ molecules. Step 3: Balance hydrogen atoms: 8 H on reactant side, so produce 4 H₂O molecules. Step 4: Balance oxygen ato
s physical properties (melting point, boiling point, solubility, density) and chemical properties (reactivity, flammability). Answers and Explanations: Describing physical properties involves measurable attributes, e.g
ting in higher boiling points. For example, water’s hydrogen bonds give it a high boiling point relative to its molar mass. Q10: Why do molecules with similar molecular weights have different physical states? A: Differences in intermolecular forces, molecular polarity, and shape affect h
