What is the importance of wiping the ice dry before introducing it to the water in the calorimeter and how would it affect the outcome of the experiment?
The specific heat of water is different from the specific heat of ice and so 'wet ice' into a calorimeter experiment can increase the mass of water in the calorimeter and become a source of unaccuracy.
Why should you use only the amounts and the materials given in the experiment?
Different amounts may produce different results.
What does NOT describe a nuclear reaction?
Relatively small amounts of energy are released or absorbed.
Describe a constant in an experiment?
In any experiment there will be many things which we need to keep the same. For example, if we are finding out how long a chemical reaction is lasting for, we need to make sure that the ingredients and the same amounts of them are used throughout the experiment. Things we need to keep the same are called constants.
How is an accurate experiment different from a fair experiment?
A fair experiment is fair wheras an accurate experiment is more accurate. LOL Joke. The latter simply means the results are to a higher degree of.... accuracy e.g instead of to 5, the result could be 5.1235 However a fair experiment is a test carried out under fair conditions. If testing more than once during the experiment you have to be sure that things remain at the same level i.e. Temperatures Amounts of reactants Time must remain the same..

What are the optimum amounts of baking soda and vinegar for an explosion in a 9 ounce water bottle?
This experiment may be very dangerous.
What do you mean by variables?
A variable in science is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by a scientist in the experiment. The depended variable is what you measure in the experiment and what is affected during the experiment. A controlled variable is one which the researcher holds constant (controls) during an experiment.
What kind of experiment was the Truman Show?
The Truman Show was a fictional experiment where a man's entire life was filmed without his knowledge and broadcast to the world as a TV show. It explored themes of reality, privacy, and free will.
Why was Erwin Chargaff's experiment important?

Can latex and acrylic water based paints be mixed together?
Some can, it depends on the exact components in both. -Experiment with small amounts and find out.
Why is it that only small amounts of uranium are needed to produce the same electricity as large amounts of coal?
Because the energy released by nuclear fission is extremely great compared with the energy released by coal burning.
What experiment would you use to show water holds heat?
use equal amounts of soil and water, two pans of the same size, an oven, and a thermometer.
