Aqueous hydrobromic acid (HBr) reacts with solid sodium hydroxide (NaOH) to produce aqueous sodium bromide NaBr and liquid water (H2O). What is the theoretical yield of water formed from the reaction of 6.5g of hydrobromic acid and 2.0g of sodium hydroxide? 

Round your answer to 2 significant figures.

Gaseous butane (CH3(CH2)2 CH3) will react with gaseous oxygen (O2) to produce gaseous carbon dioxide (CO2) and gaseous water (H20). Suppose 39g of butane is mixed with 150g of oxygen. Calculate the minimum mass of butane that could be left over by the chemical reaction. Round your answer to 2 significant digits.
