Pre-existing oxidation on the metals may influence observations. Explain how this can lead to false positives or negatives, providing one hypothetical scenario for each, using observations from your data.

i believe it is 40–40–20%

explanation:

i do not get it   at all

answer: option (b) is the correct answer.

explanation:

intensive property is the physical property which does not depend on the size of system or amount of material present in system.

for example, color, density, melting point, boiling point etc are all intensive properties.

thus, we can conclude that the boiling point and color of a substance are both examples of intensive properties because they do not depend on the amount of matter in the sample.
