Sulfuric acid and sodium carbonate react to form carbon dioxide, water, and sodium sulfate as shown in the balanced equation below: H2SO4(aq) + Na2CO3(s) + CO2(g) + H2O(1) + Na2SO4(aq) In the presence of excess sulfuric acid, how many moles of CO2 would be released if you have 12.50 g of Na2CO3(s)? The molar mass of sodium carbonate is 106.0 g/mol, the molar mass of sulfuric acid is 98.08 g/mol, and the molar mass of carbon dioxide is 44.01 g/mol....

Why does octanol has higher bouling point than water? I belive that water can form 4 H bonds and more polar than octanol. So I expected to see higher boiling point for water. But actually, octanol has higher boiling point than water. Does it imply that octanol has stringer intermolecular force? If so, could anyone explain why?
