Answer: Option (d) is the correct answer.
Explanation:
A branch of science that deals with substance or matter identification and why substances combine or separate is known as chemistry.
Chemistry is based on classification of elements and most of its work includes experimentation in order to verify that the results obtained are appropriate or not.
Thus, we can conclude that the statement, it gives the same result when an experiment is repeated, is true.
The statement which best explains why chemistry is reliable is: D. It gives the same result when an experiment is repeated.
Chemistry can be defined as a branch of science that is mainly focused on the study of chemical elements, matter and substance, so as to investigate and identify their composition, structure and properties. Thus, Chemistry is a branch of science that deals with the study of matter based on their structure (form), reactions, composition, and properties.
Basically, scientists are able to determine and understand; how and why matter interact, substance combine or science by conducting experiments in Chemistry.
Furthermore, Chemistry is typically based on conducting experiments, gathering data and analyzing test results, so as to verify the accuracy, authenticity and credibility of a result.
Hence, Chemistry is reliable because the result from an experiment is always the same when it is repeated.
