Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".

The ethanol (MM = 46.08 g/mol) reacts with the dichromate ion in potassium dichromate (MM = 294.20 g/mol) to produce the green chromate ion in chromium sulfate (MM = 392.21 g/mol). The sample is analyzed in a hand-held spectrophotometer, and the amount of light transmitted is converted into an electrical signal. The signal is then converted to an absorbance value which is proportional to the amount of ethanol in a sample. Calculate the grams of chromium sulfate formed from 0.0250 g ethanol. Enter the value with no units.

You are a forensic scientist. You are investigating a murder involving poison. The victim was poisoned with a compound called di-chlorobenzene, whose formula is C6H4Cl2. Autopsy results show that the victim’s body contained about 27.5 g of the poison, but the actual amount could have been slightly higher due to tissue absorption. The main suspect is his wife, Suzanne, who works as a chemistry professor. Records show that she purchased 15 g of benzene (C6H6) two days before the murder. Benzene is one of the compounds use to make the poison. She claims she was using it to make methyl benzene (C6H5CH3), an innocuous compound, for use in her lab. She shows you the bottle of methyl benzene she claims to have made. It contains 25 g of methyl benzene. To produce di-chlorobenzene, the reaction is: Cl2(g) + C6H6(l) ⟶⟶ C6H4Cl2(l) + H2(g) To produce methyl benzene, the reaction is: CH4(g) + C6H6(l) ⟶⟶ C6H5CH3(l) + H2(g) Use stoichiometry to solve this case. Be sure to show all…
