Question

Dominic and Eva are using the same type of stopwatches to measure the time it takes for a chemical reaction to occur. They each use the same stopwatch to measure the time. These are their results: Person Trial 1 Dominic 78 seconds Eva 81 seconds Why are their results unreliable and can lead to a pseudoscientific claim? Group of answer choices They did not repeat their tests multiple times. They used the same type of stopwatch. They did not change the reactants in their chemical reactions. Only one person should have collected the data.

Answer 1

They did not repeat their tests multiple times

Step-by-step explanation:

Answer 2

The correct answer is - They did not repeat their tests multiple times

Step-by-step explanation:

If a scientific process or practice which is fundamentally based on believes or idea that has no valid evidence and not proved scientifically, such type scientific process called Pseudoscience or the false science.

In this case, Both Dominic and Eva performed experiments and recorded different time periods by the same stopwatch for the same chemical reaction.

This could result in an error in the data they get and affect the conclusion or results. To avoid this experiment must be repeated to be sure of the result and eliminate errors.
