A tank contains a mixture of helium, neon, and argon gases. If the total pressure in the tank is 490. mmHg and the partial press

OleMash [197]

Answer: The partial pressure of neon is 173 mmHg

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

$p_{total}=p_A+p_B+p_C$

Given : $p_{total}$ =total pressure of gases = 490 mm Hg

$p_{He}$ = partial pressure of Helium = 215 mmHg

$p_{Ar}$ = partial pressure of argon = 102 mm Hg

$p_{Ne}$ = partial pressure of neon= ?

$p_{total}=p_{He}+p_{Ar}+p_{Ne}$

$490=215+102+p_{Ne}$

$p_{Ne}=173mmHg$

Thus partial pressure of neon is 173 mmHg

draw the lewis structure for CO2, H2CO3, HCO3-, and CO3 2-.Rank these in order of increasing attraction to water molecules. Expl

gavmur [86]

Answer:

The structures are attached in file.

Hydrogen bonding and intermolecular forces is the reason for ranks allotted.

Explanation:

In determining Lewis structure, we calculate the overall number of valence electrons available for bonding. Making carbon (the least electronegative atom) the central atom in the structure, we allocate valence electrons until each atom has achieved stability.

In order of decreasing affinity to water molecules:

$CO_{3}^{2-} > HCO_{3} ^{2-} > H_{2} CO_{3}$

This is due to the fact that the $CO_{3}^{2-}$ will accept protons more readily than the bicarbonate ion, $HCO_{3} ^{2-}$ . Carbonic acid, $H_{2} CO_{3}$ will not accept any more protons, hence it is the least attractive to water molecule, even though soluble.
