Calcula el pH de las siguientes sustancias formadas durante una erupción volcánica:
Virty [35]

<em>Calculate the pH of the following substances formed during a volcanic eruption: </em>

<em>• Acid rain if the [H +] is 1.9 x 10-5 </em>

<em>• Sulfurous acid if [H +] = 0.10 </em>

<em>• Nitric acid if [H +] = 0.11</em>

<em />

<h3>Further explanation  </h3>

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.  

pH = - log [H⁺]  

  • pH acid rain

\tt pH=-log[1.9\times 10^{-5}]\\\\pH=5-log1.9\\\\pH=4.72

  • pH Sulfurous acid

\tt pH=-log[10^{-1}]\\\\pH=1

  • pH Nitric acid

\tt pH=-log[11\times 10^{-2}]\\\\pH=2-log~11=0.959

What is the mole fraction of water in pure water
irinina [24]
In pure water, all of the molecules in the liquid are water molecules so the mole fraction is 1 (100 % H2O, 55 mol/L). In sea water, the concentration of water molecules in the solution is less than that of pure water so the vapor pressure of sea water is also lower.

3.75 g of an unknown gas at 59 °C and 1.00 atm is stored in a 1.35-L flask. What is the molar mass of the gas?
MAXImum [283]
You need to find moles of the gas, so you would use the ideal gas law:
PV=nRT
Pressure
Volume
n=moles
R= gas constant
Tenperature in Kelvin
n= PV/RT
(1.00atm)(1.35L)/(.08206)(332K) = 0.050mol
Molar mass is grams per mole, so
(3.75g/.050mol) = 75g/mol
