To determine the volume of the gas mixture, we first need to determine the total pressure of the mixture. To do this, we use the definition of the partial pressure of a component in the gas mixture. The partial pressure is the pressure of a component as if it were alone in the container. It is equal to the mole fraction of the component times the total pressure of the system. From this, we determine total pressure.
Pneon = xneonP
P = Pneon / xneon
P = 8.87 kPa / (225 / (225 + 320 + 175))
P = 8.87 kPa / 0.3125 = 28.384 kPa
Assuming ideal gas, we use PV=nRT to calculate for the volume,
PV = nRT
V = nRT / P
n = 225 mg ( 1 mmol / 20.18 mg) + 320 mg ( 1 mmol / 16.05 mg ) + 175 mg ( 1 mmol / 39.95 mg ) = 35.47 mg = 35467.0 g
V = 35467.0 (8.314) (300) / (28384) = 3116.68 m^3
We can measure the properties of several unknown solids by some of the characteristics :
Covalent.
Ionic.
Metallic.
Network covalent.
<span>covalent bonds are weaker than ionic and create molecular compounds. these have low melting and boiling points.
</span>
<span>ionic compounds are very strong bonds, it takes a lot of energy to melt and boil these compounds. these are brittle compounds.
</span>metallic bonds are found in metals, of course. these are described as "sea of electrons" because the valence elctrons of each metal atom can freely move between the metal atoms in the crystal. this is what allows for electric conductivity in metals, the easy flow of electrons through the metal.
<span>network covalent are covalent bonds. the are different from covalent bonds because they are much stronger bonds. a diamond is made only of C. one sees in other compounds that carbon bonds are covalent and weaker than ionic. in a diamond, the C atoms are in a network of covalent bonds and, as we see everyday, graphite, also only carbon, is so weakly held together that we can rub the tip of a pencil and the C comes off on our hands</span>
The amount of alcohol contained in each of the listed beverages can be compared as follows; 1/2 oz of 80 proof liquor > 5 oz of wine (12% alcohol) > 12 oz of wine cooler (5%alcohol) = 12 oz of beer (5%alcohol) .
A drink that contains alcohol must be an intoxicating beverage. The extent of intoxication of an alcoholic beverage depends on the amount of alcohol that the beverage contains. There are various types of alcoholic beverages as listed in the question.
