Answer:
Precise but not accurate.
Explanation:
We can tell the performance of the balance is precise, because the repeated measurements give values close to one another.
However, the performance of the balance is not accurate, as the mean value of the repeated measurements (195.587) is not close to the value considered as true (in this case the standard calibration mass with a certified value of 200.002 g).

Silver is A precious shiny grayish-white metal, the chemical element of atomic number 47. Silver is sometimes found in nature in metallic form. It forms a sulfide mineral Ag 2 S called acanthite. Mineral forms of silver include sulfides formed with antimony called Stephanite, miargyrite and pyrargyrite. Silver is a naturally occurring element on the periodic table and can be found in natural deposits throughout the world. As such, it was discovered in 5000 BC, but not invented, by people.
Answer:second law of thermodynamics
Explanation:the second law of thermodynamics states that the total entropy of an isolated system can never decrease over time and is constant if only if all processes are reversible.
Answer:
3 M
Explanation:
Molarity equation: M = n/v
n = moles of solute
v = liters of solution
9 moles of NaCl / 3 L
9/3 = 3 M
