If 0.0106 g of a gas dissolves in 0.792 L of water at 0.321 atm, what quantity of this gas (in grams) will dissolve at 5.73 atm?
Alex73 [517]

Answer:

0.189 g.

Explanation:

  • This problem is an application on <em>Henry's law.</em>
  • Henry's law states that the solubility of a gas in a liquid is directly proportional to its partial pressure of the gas above the liquid.
  • Solubility of the gas ∝ partial pressure
  • If we have different solubility at different pressures, we can express Henry's law as:

<em>S₁/P₁ = S₂/P₂,</em>

S₁ = 0.0106/0.792 = 0.0134 g/L and P₁ = 0.321 atm

S₂ = ??? g/L and P₂ = 5.73 atm

  • So, The solubility of the gas at 5.73 atm (S₂) = S₁.P₂/P₁ = (0.0134 g/L x 5.73 atm) / (0.321 atm) = 0.239 g/L.

<em>The quantity in (g) = S₂ x V = (0.239 g/L)(0.792 L) = 0.189 g.</em>

What is the name of the ionic compound AlBr3?
Aleksandr [31]

Answer: Correct name will be is aluminum bromide

Explanation:

In a molecular formula ,AlBr_3

Aluminium atoms present = 1  

Bromine atoms present = 3

Charge on aluminium is +3 and charge on bromine is -1.

While naming:

  • Name of the cation is written first. Simple name of the element is written
  • After name of cation name of an anions written with suffix 'ide' in the end.

So, the name of AlBr_3 will be aluminium bromide.
