Answer:
Atoms of elements at the top of a group on the periodic table are smaller than the atoms of elements at the bottom of the group. ... The valence electrons of the larger atoms are farther from the nucleus and are easier to remove, so the metals near the bottom are more reactive than those at the top.

Answer:
4.84 × 10⁻⁶ M
Explanation:
First, we will calculate the partial pressure of Ar (pAr) using the following expression.
pAr = P × χAr
where,
P: total pressure
χAr: mole fraction
pAr = P × χAr
pAr = 0.370 atm × 9.34 × 10⁻³
pAr = 3.46 × 10⁻³ atm
We can find the solubility of Ar in water (S) using Henry's law.
S = kH × pAr
where
kH: Henry's constant
S = kH × pAr
S = 1.40 × 10⁻³ M/atm × 3.46 × 10⁻³ atm
S = 4.84 × 10⁻⁶ M
