How can bias lead to an incorrect conclusion or experimental error?
When in doubt, find what you like.
What sources of experimental error lead to a percent yield higher than 100 percent?
The reaction may have not been complete yet, therefore resulting in a higher percent yield than 100%
Why is experimental design a key factor in science inquiry?
The experimental design is always a key factor in the science inquiry. The experimental design shows the methods that lead to the science.
Which material has greater density lead or feathers?
Lead
Explain whether the rinsing of conical flask with the standard sodium carbonate would lead to experimental error?
It depends on the nature of the chemical going into the conical flask. If you are titrating for carbonate or sodium ions there could be an error. Whatever, the product going into the flask, first flush it with a little of that product. Throw it away and then titrate. However, it they have been cleaned in a lab washing machine,, by a lab. technician, then the conical flask should be 'whistle' clean. L:ab. technicians use a special water soluble of pH 7 cleaner.
Which has a greater weight a kilogram of butter or a kilogram of lead which has greater density?
They both weight a kilogram. Lead has a higher density.
Which has greater weight a kilogram of butter of kilogram of lead what is greater density which has greater volume?
They both weigh the same: 1kg = 1kg. The kg of butter has a greater volume and the kg of lead has a higher density.
What has a greater mass 2 atoms of lead or 5.1 X 10-23 mole of helium?
The weight is greater for 2 atoms of lead.
Which has greater volume lead or feathers?
the same
What statement of no difference in experimental treatment?
When setting up an experimental procedure one prepares a control treatment as well as one or more experimental treatments. At the end of the experiment, if there is no difference between the experimental and control groups the experiment is typically said to be not conclusive. With a typical set-up, this result generally fails to lead to a rejection of the null hypothesis.
