Types of Chemical Reactions

Chem 11 More Reaction Types Name: Predict the products and balance the following reactions of all types. Include the subscript states and classify the reactions. a. 2NaCl(s) → 2Na(s) + Cl₂(g) Classify the following reactions as endothermic or exothermic. a. Cl₂ + KI → KCl + I₂ + energy exo b. Mg + O₂ → MgO exo c. energy + NaClO₃ → NaCl + O₂ endo d. C₈H₁₈ + O₂ → CO₂ + H₂O + energy exo e. C + H₂O → CO + H₂ ΔH = 113 kJ endo f. H₂O₂ → H₂O + O₂ + 190 kJ exo g. N₂ + O₂ + 181 kJ → NO endo Answers: If you simply copy these you are only cheating yourself! a. 2 NaCl → 2 Na(s) + Cl₂(g) decomposition b. 2 Sr(s) + O₂(g) → 2 SrO(s) synthesis c. 2 C₆H₁₄(l) + 19 O₂(g) → 12 CO₂(g) + 14 H₂O(g) combustion d. Zn(NO₃)₂(aq) + Pb(s) → No RXN single replacement e. Pt(SO₄)(aq) + Fe(s) → FeSO₄(aq) + Pt(s) single replacement f. 2 NaNO₃(aq) + CuSO₄(aq) → No RXN double replacement g. 2 (NH₄)₃PO₄(aq) + 3 FeCl₂(aq) → 6 NH₄Cl(aq) + Fe₃(PO₄)₂(s) double replacement h. 2 C₆H₁₄(l) + 19 O₂(g) → 12 CO₂(g) + 14 H₂O(g) combustion i.
