Review Organic Chemistry

1. A cyclic ketone which hasn't got branches and has a Pm=84g/mol contains  71.4% C and 9,5%H. Tell its empiric and its mollecular fórmula. Draw its geometric fórmula. 
2. A compound burns energically, boils at 60°C and solves into water. It doesn't carry electricity. Can it be organic?
3. Name:

1. Write the formula of 

• 2 ethyl 2 propen-al
• 2 propyl 3 chloro butanoic acid
• 3 flúoro 2 cyclopentenone 

4ESO Stoichiometry as a whole

1. When 200 g of NaHCO3 95% react with HCl 0.5M they produce Sodium chloride, water and a gas which provoques global warming  is released. a) Write the chemical equation  (balance it). b)Determine the volume of HCL 0.5M you need c)Determine the volume of gas measured at 20°C and 0.9 atm.
2. In a blast furnace, Iron is reduced from Fe2O3 to Fe (steel in fact) with graphite (C), which turns into CO2. Write the chemical equation. Determine the mass of graphite they need to get a kg of steel, and the volume of CO2 measured at 500°C and 2.5 atm.

Data: Pm Cl:35.5; Na 23; C 12; O 16; H 1 g/mol R=0.082 atm•l/Kmol
