Tamifu(Oseltamivir), C₁ H₂N₂O₁, an antiviral drug used to treat influenza (Figure 1). The preparation of Tamiflu begins with the extraction of shikimic acid from the seedpods of the Chinese spice, star anise (icium verum)(Figure 2). From 2.6 g of star anise, 0.13 g of shikimic acid can be obtained and used to produce one capsule containing 75 mg of Tamiflu. The usual adult dosage for treatment of influenza is two capsules of Tamiflu daily for 5 days. igure Tamia <1 of 3 > Part D How many capsules containing 75 mg of Tamiflu could be produced from 152 g of star anise?

Based on the balanced reaction 4 HCl + O2 →2 H2O + 2 Cl2  how many moles of  Cl2 could be made by the complete reaction of 20 moles of HCl and excess O2?

In a combustion reaction, the most common fuel that burns contains compounds called hydrocarbons. This organic compound reacts quickly with oxygen and produces carbon dioxide (CO2) and water vapor (H2O). The reaction typically gives off heat and light as well.  The combustion of methane is represented by the equation: CH4 + 2O2 → CO2 + 2H2O 1. In the above reaction what compound is oxidized? 2. Give another example of a hydrocarbon combustion reaction and write the equation.
