Boiling point.
It is the temperature at which the vapor pressure of the liquid equals the vapor pressure of tha atmosphere that surrounds it, which permit to defeat the attraction among the molecules in the liquid phase and pass to the gas phase.
The molar mass of CO is 28 g/mol while that of CO2 is 44
g/mol. Let us calculate the total moles present in the container.
total moles = [5g / (28 g/mol)] + [5g / (44 g/mol)]
total moles = 0.2922 mol
Using PV = nRT, we get the pressure:
P = nRT / V
P = (0.2922 mol * 0.0821 L atm/mol K * 323.15 K) / 0.75 L
<span>P = 10.34 atm</span>
A is the answer
In an ozone molecule, the three atoms must be connected, so there must at least be a single bond between them. Place
dots in pairs around the oxygen atoms until each oxygen atom has eight valence electrons, starting with the atoms on the
outside and doing the central atom last if there are enough. Do not exceed the total number of valence electrons
identified in part A. Remember that the dashes between the oxygen atoms, which represent single bonds, each indicate
the presence of two valence electrons
It all depends on the objects' densities ,because if they're less dense than the oil they will not even sink to the bottom of the beaker
