Scientific Method

The scientific method is the basis of scientific investigation. A scientist will pose a question and formulate a hypothesis as a potential explanation or answer to the question. The hypothesis will be tested through a series of experiments. The results of the experiments will either prove or disprove the hypothesis. This category should contain questions and answers regarding the scientific method.

If 500 g of KCIO decomposes and produces 303 g of KCI how many grams of O2 are produced?

The balanced reaction from the problem is 2KCIO -> 2KCI + O2 So if 303g of KCI is formed that is approximately 1.702 mol (303 g / MW of KCI (178 g/mol)). For every 2 moles of KCI formed there is 1 mole of O2 formed. Therefore, 0.851 mol of O2 are produced and multiplying by the MW of oxygen (32 g/mol) will yield 27.23 g of oxygen.

What was Dr Kettlewell's hypothesis?

He said that moths with darker color were less likely to be eaten by birds. He said that pollution causing soot on walls of building "selected" for darker colored moths because the birds could not see them as well. So more darker moths produced offspring like themselves. Kettlewell said that differential selection by birds using their eyesight to find prey was sufficient to explain the changes in darker pigment, and that this demonstrated the effectiveness of natural selection as an evolutionary force.
