The solubility of N2in blood at 37°C and at a partial pressure of 0.80 atm is 5.6 × 10−4mol/L. A deep-sea diver breathes compres
Luda [366]

Solution :

According to Henry's law of solubility, we have c = kp

Henry's law constant, $k=\frac{c}{p}$

                                      $=\frac{0.00056}{0.80}$

                                      = 0.0007 mol/L.atm

When the pressure is = 4 atm

The solubility is c = 0.0007 mol/(L.atm) x 4 atm

                             = 0.0028 mol/L

Therefore, in a 5 liter of blood, the moles of nitrogen dissolved

= 0.0028 x 5

= 0.014 moles

At the surface, the solubility is = 0.00056 mol/L

So the moles of the nitrogen dissolved = 5 x 0.00056

                                                                  = 0.0028 moles

Therefore, the number of moles of nitrogen released = 0.014 - 0.0028

                                                                                         = 0.0112 moles

Given total pressure = 1 atm                                                                        

Temperature = 37 degree C

                     = 37 + 273

                      = 310 K

R = $0.0821\ L -atm/ mol.K $

Therefore, volume of the nitrogen is

$V=\frac{nRT}{P}$

$V=\frac{0.0112 \times 0.0821 \times 310}{1}$

  = 0.285 L

Write a net ionic equation to show why solid lithium hydroxide, lioh (s), forms a basic solution when it dissolves in water.
Doss [256]
<span>Solid lithium oxide, the basic anhydride of lithium hydroxide reacts with water to make lithium ions and hydroxide ions. Li2O(s) + H2O(l) --> 2LiOH(aq) ...... molecular equation Li2O(s) + H2O(l) --> 2Li+ + 2OH- ..... ionic equation, and net ionic equation BUT!!!!! The decomposition of potassium chlorate into KCl and O2 gas does not take place in aqueous solution. The equation should be. 2KClO3(s) --> 2KCl(s) + 3O2(g) No ionic equation. There is nothing in solution. This reaction does not occur in aqueous solution. 2Na(s) + I2(g) --> 2NaI(s) No ionic equation. There is nothing in solution. Clearly, to have an ionic equation there must be ions, and to have ions the salts have to be dissolved in water.</span>
