1. Complete and Balance the following redox equation.
MnO4 + H +Br-->Mn2 +Br2 +H2O (acidic Solution).
The sum of the smallest whole number coefficients is
2. Consider the reaction:
SO2(g) + NO2(g) ? SO3(g) + NO(g); K = 12.00?T
The reaction vessel is charged initially with SO3(g) and NO(g), each at a partial pressure of 0.500 atm. In the space below, enter the equilibrium the partial pressure of SO2(g) in units of atm
In the Hofmann Degradation of amines an amine is exhaustively methylated with Methyl Iodide and the resultant compound treated with Silver Hydroxide and heated. An alkene is formed which is not the Saytzeff product.
Are there any other particular ones more important or can some of them actually have a harmful effect on the human body.
