<u>Answer:</u> The correct answer is Option E.
<u>Explanation:</u>
Atomic radius is defined as the total distance measured from the nucleus of an atom to the outermost shell.
<u>Trend down the group:</u>
Moving from top to bottom, a new shell gets add up around the nucleus and the outermost shell gets far away from the nucleus. Due to this, the distance between the nucleus and outermost shell increases, which results in the increase of atomic radii of the atom.
<u>Trend across the period:</u>
Moving from left to right in a period, more and more electrons gets add up in the same shell. The attraction between the last electron and the nucleus increases. This results in the shrinkage of size of an atom. Thus, decreasing the atomic radii of the atom.
Hence, the correct answer is Option E.
Answer: A volume of 600 mL of 3.0 M 
solution can be prepared by using 100.0 mL OF 18 M .
Explanation:
Given: 
= ?, 
, 
Formula used to calculate the volume is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that a volume of 600 mL of 3.0 M solution can be prepared by using 100.0 mL OF 18 M .
Answer:
Meteorologists use computer programs called weather models to make forecasts. Since we can't collect data from the future, models have to use estimates and assumptions to predict future weather. ... A seven-day forecast is fairly accurate, but forecasts beyond that range are less reliable.
Answer:
Explanation:
Helo,
In this case, the pressure must be computed as follows:
Which is using the density of mercury (13.6 g/mL) and its height, thus, we obtain (using the proper units):
Best regards.
