Atomic radii increase when going down a group and decreases when going towards the anion periods. So A and D.
Hello!
To find the number of moles that are in the given amount, we need to divide the total number of atoms by Avogadro's number, which is 1 mole is equal to 6.02 x 10^23 atoms.
5.0 x 10^25 / 6.02 x 10^23 ≈ 83.0564
Therefore, there are about 83.06 moles of iron (sigfig: 83 moles).
Answer:
Situation B indicates the significant depression of temperature in the wet bulb thermometer.
Answer Statement: B
Explanation:
Temperature Depression & Relative Humidity
As we can see that there are four cases to study the affect of relative humidity on the temperature measured by thermometers, set up in different situations i.e., one is dry and the other one is dry.
As situation B describes the most admissible temperature drop in the wet bulb thermometer with a relative humidity of approximately 17% i.e., this can be the appropriate to reflect the lowest relative humidity with a fact that the relative humidity reduces with a larger count of temperature depression. Whereas, the relative humidity for other situations are resulting much higher.
