How do you ensure that an experiment is a fair test chem?
To ensure an experiment is a fair test in chemistry, you should control all variables except for the one being tested.

Why should you use tongs and not fingers to handle cooled crucible and lid?
Tongs should be used to handle a cooled crucible and lid to prevent burns or injury from residual heat.

To determine whether Fleming's hypothesis should be supported or rejected based on an experiment, one would need to analyze the results of the experiment in relation to the hypothesis. If the data from the experiment aligns with the predictions made by Fleming's hypothesis, then it should be supported. However, if the results contradict the hypothesis, it may need to be rejected or revised.
Describe the relationships between pure chemistry and applied chemistry?
