You can use this formula to solve for density--> Density= PM/ RT, where P is pressure, M is molar mass, R is the gas constant and T is temperature.
P= 1.75 atm
M= 16.01 g/ mol
R= 0.0821 atm·L/ mol·K
T=337 k
density= (1.75 x 16.01)/ (0.0821 x 337)= 1.01 g/L
Explanation:
In a Lewis dot diagram, the electrons are arranged so that, when full, two electrons placed beside each other are on four sides of the element symbol.
An electron is 3-dimensional, so you can start on any side on a 2D diagram.
Continue this pattern depending on how many electrons you have:
When adding an electron after the first, it is placed on the next side going either counterclockwise or clockwise. Which ever direction you choose, be consistent.
After the fourth electron, so that one electron is on each side, place a dot beside your first electron and continue the pattern.
Answer:
If a pure compound is distilled, the temperature of the head will be compared to the temperature of the pot. However, if there is an impurity present that strongly interacts with the molecules of the liquid, then the temperature must be increased to increase the vapor pressure of the liquid, eventually to atmospheric pressure, allowing the liquid to boil. Therefore, at the boiling point, the temperature of the pot will be higher than the temperature of the head.
Explanation:
when temperatures increase, pressures also do so, thus reaching boiling points where liquid states become gaseous.
