Answer:
You can learn about common things happening to the environment that aren't good. Such as erosion, and the effects it has on the land surrounding it.
Explanation:
0.2 m/s! keep in mind, speed= distance divided by time :D
Calcium would be more reactive because it is closer to francium on the periodic table, francium is the MOST reactive element.
Answer: Infrasound because sound waves travel easily through water to accessible buoys.
Explanation: its installation: underwater microphones hung from buoys near a volcano. how it works: senses low-frequency sound waves near a volcano. Since in its installation it specifies that it has UNDERWATER microphones and the question asks in predicting an eruption from an UNDERSEA volcano, that makes perfect sense.
Answer
is: 1) ccl4, kb = 29.9°c/m, carbon tetrachloride has the greatest boiling point
elevation.
The boiling point elevation is directly
proportional to the molality of the solution according to the
equation: ΔTb = Kb · b.
<span>
ΔTb - the boiling point
elevation.
Kb - the ebullioscopic
constant.
b - molality of the solution.
So the highest boiling poing elevation will be for solution with highest ebullioscopic constant because molality is the same.</span>
