A neutral atom has the same number of protons as electrons.
Explanation:
Boiling point is the temperature at which vapor pressure of a liquid becomes equal to the atmospheric pressure.
More strong interactions present in the atoms of a compound more heat is required to break it. Hence, greater will be its boiling point.
As the boiling point of oxygen is 90 K so, at a temperature greater than it will change the state of oxygen from liquid to gas.
Similarly, the boiling point of nitrogen is 77 K so, at a temperature 95 K the state of liquid will also change from liquid to gas.
Cis-trans isomerism, also known as geometric isomerism or configurations isomerism is a term used in organic chemistry
<span>If there are 38 g of CFC, then there will be 120.9135 g of CFCl2 per mol. You will multiply this times the number of moles of Cl (2) for every mole of CFCl2, and then by the number of grams of Cl per mole, which is 35.4532: (38.0 g CF2Cl2) / (120.9135 g CF2Cl2/mol) x (2 mol Cl / 1 mol CF2Cl2) x (35.4532 g Cl/mol) =
22.3 g Cl in CF2Cl2
Next, if there are 38 g of CFC, there will be 137.3861 g of CFCl3 per mole. You will multiply this times the number of moles of Cl (3 this time) for every mole of CFCl3. You will then multiply this by 35.4532 again:
(38.0 g CFCl3) / (137.3681 g CFCl3/mol) x (3 mol Cl / 1 mol CFCl3) x (35.4532 g Cl/mol) =
29.4 g Cl in CFCl3
Continue following these steps until you are able to multiply 1 mole of Cl per 1 mol CF3Cl by 35.4532:
(38.0 g C2F3Cl3) / (187.3756 g C2F3Cl3/mol) x (3 mol Cl / 1 mol C2F3Cl3) x (35.4532 g Cl/mol) =
21.6 g Cl in C2F3Cl3
(38.0 g CF3Cl) / (104.4589 g CF3Cl/mol) x (1 mol Cl / 1 mol CF3Cl) x (35.4532 g Cl/mol) =
12.9 g Cl in CF3Cl</span>
