The oxidation number of a pure element is zero.
Answer:
They learned because they keeped studying they would never give up and if they found something new or interesting they may have just studied it more.
Explanation:
Sample A dissolves most slowly because it tells us, first off, that A dissolves slower than B. It also tells that B dissolves more slowly than C. This means that’s A is slower than B and C, because there is no way A would be faster than C if B is already slower (because A is slower than B.) I hope this helps. :)
Answer:
1.These results are accurate because the collected data is very close to the actual value.
4.These results are precise because all three trials are within a very close range.
Explanation:
Although in the ordinary language the terms precision and accuracy may be confused, in science those terms refer different properties of the measurements.
The accuracy is how close a measurement is to the true value, while the the precision refers to the reproducibility and repeatability, this is how the results show the same (close) value.
To differentiate precision and accuracy, It is very illustrative, to use the image of a throwing arrows to a target: if the arrows get close to the center of the target, then the results are accurate (close to the goal). If the arrows are not close to the cener of the target, but they are all close to each other, then the result is precise (the arrows land, approximately, in the same spot every time).
