Answer:
Error.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
Cause and effect can be defined as the relationship between two things or events in which an occurrence one (cause) leads to the occurrence of another (effect).
Experimental error is a factor that can arise from incorrect use of measuring tools or malfunctioning equipment such as thermometer, barometer, multimeter, voltmeter, ammeter, vernier caliper, etc. This error usually causes test results to be inaccurate, incorrect and as such leading to wrong experimental conclusions.
Also, one common example of an experimental error is the error due to parallax.
Atoms must gain or lose electrons in order to become ions if they are to form ionic bonds.

Answer:
The answer is: Law of multiple proportions
Explanation:
The law of multiple proportions is a law of chemical combination given by Dalton in 1803.
According to this law, if more than one chemical compound is formed by combining two elements, then the mass of an element that combines with the fixed mass of other element is represented in the form of small whole number ratio.
<u>Therefore, is an illustration of the law of the law of multiple proportions.</u>
