True. Each contour line on a topographic map represent a certain elevation; the closer they are, the steeper the surface is. All points on a contour line are the same elevation.
<u>Answer:</u> The order of reactivity will be F > O > N > C > B.
<u>Explanation:</u>
Reactivity of an element is defined as the tendency for it to gain or loose electrons easily.
From the given elements, all are non-metals except boron.
Boron is a metalloid and it does not attract or loose electrons easily. Hence, it is the least reactive element.
Reactivity of non-metals increases across a period because of the decrease in size and electrons are more attracted towards the nucleus and hence, can gain electrons easily. Therefore, the most reactive metal will be fluorine.
Hence, the order of reactivity will be F > O > N > C > B.

Answer:
58.32
Explanation:
The mass number is one mole and for Mg it is 24.306 for O it is 15.999 and for H it is 1.008. because O and H have 2, you multiply them by 2 and add all the numbers and it equals 58.32
