I would go with b: the reproducible of a measured value. but im not 100%

Answer:

the agreement between a measured value and an accepted value

Explanation:

Accuracy measures how close a measured value is to a standard value. For example, if the weight of a bag of rice is 1 kg and the measured value is 0.90 kg rather than 0.75 kg, then the former measure value is more accurate than the later measured value.

Precision on the other hand is how close are the measured values to one another. For example, if that same 1 kg rice bag was measured 3 times and the readings were 0.75 kg, 0.73 kg and 0.74 kg then the measured values are precise but inaccurate.

What is a cation and where can you find it on the periodic table?
Maslowich

Answer:

A cation is an ion with fewer electrons than protons. Therefore, it has a positive charge. The electric charge on a proton is equal in amount to the charge on an electron. Anions are atoms or radicals (groups of atoms), that have gained electrons. Since they now have more electrons than protons, anions have a negative charge. Halogens always form anions, alkali metals and alkaline earth metals always form cations. Most other metals form cations (e.g. iron, silver, nickel), whilst most other nonmetals typically form anions (e.g. oxygen, carbon, sulfur).

Explanation:

An anion and cation cannot be specifically found on the periodic table.

c. Conclusion is <em>incorrect</em> because a conclusion is a decision you make to accept or reject your hypothesis.

d. Hypothesis is <em>incorrect</em> because a hypothesis is a proposed explanation for why something happens.
