How do the names of molecular compounds differ from the names of ionic compounds.
34kurt

Long Answer:

Ionic: Cation is named first followed by the anion.

If it's an ionic compound with a transition metal, there are more than one possible ion. Molecular - named with the least electronegative ion first + prefixes are given to both ions to indicate number of atoms in each element.

Short Answer: Ionic compounds- Cation is named first, followed by the anion.

What is the solubility of ethylene (in units of grams per liter) in water at 25 °C, when the C2H4 gas over the solution has a pa
vredina [299]

<u>Answer:</u> The solubility of ethylene gas in water is 9.16\times 10^{-2}g/L

<u>Explanation:</u>

To calculate the molar solubility, we use the equation given by Henry's law, which is:

C_{C_2H_4}=K_H\times p_{C_2H_4}

where,

K_H = Henry's constant = 4.78\times 10^{-3}mol/L.atm

C_{C_2H_4} = molar solubility of ethylene gas = ?

p_{C_2H_4} = partial pressure of ethylene gas = 0.684 atm

Putting values in above equation, we get:

C_{C_2H_4}=4.78\times 10^{-3}mol/L.atm\times 0.684atm\\\\C_{C_2H_4}=3.27\times 10^{-3}mol/L

Converting this into grams per liter, by multiplying with the molar mass of ethylene:

Molar mass of ethylene gas = 28 g/mol

So, C_{C_2H_6}=3.27\times 10^{-3}mol/L\times 28g/mol=9.16\times 10^{-2}g/L

Hence, the solubility of ethylene gas in water is 9.16\times 10^{-2}g/L
