In the reaction A _ products, at t = 0, [A] = 0.1565 M. After 1.00 minute, [A] = 0.1498 M and after 2.00 minutes, [A] = 0.1433. (a) calculate the average rate of the reaction during the first minute and then during the second minute. (b) why are these two rates not equal?

3-ethyl-4-methylhexa-1,3-diene undergoes a combustion reaction. For this reaction, the following concentrations were used: [O2] = 0.06 M, [CO2] = 0.09 M and [H2O] = 0.10 M. Determine the concentration (in mol/L) used of 3-ethyl-4-methylhexa-1,3-diene if the following thermodynamic parameters were determined for the reaction at 25 C: _H = -763.02 kJ/mol and _S = -2542.01 J/K mol.

Calculate the mass (in pounds) of carbon dioxide and carbon monoxide emitted by burning a gallon of gasoline. Although gasoline is a mixture of many components, simplify the calculation assuming the gasoline fuel is 20% n-heptane, 40% n-octane, 20% n-nonane and 20% n-decane on a mass basis. You may also assume that gasoline behaves ideally, and 90% of each component of the fuel combusts conpletely, […]

Create 5-6 slides excluding title about the kinetics and mechanism of the oxidation of bromothymol blue by permanganate ion in perchlorate acid solution. The kinetics and mechanism are based on the 5 pages research journal attached together in this question. No need to create the content from scratch. Its just designing the presentation.

When heavy metals such as lead (Pb), mercury (Hg), cadmium (Cd) and arsenic (As) build up in the body they can become toxic. Chelation therapy is a useful tool to treat heavy metal poisoning. In this medical procedure special drugs that can act as ligands are used to bind strongly to these metal ions. The resulting metal-drug complexes are readily excreted from the body thus […]
