Given the parent compound, draw the mass spectrum fragment that is observed at m/z 77. Include any hydrogen atoms and the charge. Its 6 carbon ring with 3 double bonds and a Cl coming off the of it.
Answer:
<u>Option B is correct</u>
Explanation:
Step 1: Define volatility
In chemistry, the term volatility, is a way to describe how readily a substance transitions from a liquid phase to a gas phase, also called evaporating.
At a given temperature and pressure, a substance with high volatility is more likely to evaporate more quickly , while a substance with a lower volatility is more likely to be a liquid or solid, so not to evaporate or slower.
The higher the volatility, the higher the (vapor) pressure of a compound. Increasing temperature means the vapor pressure will also increase,
Step 2: In this case:
⇒ O<u>ption A is false</u> because the pressure will be higher when volatility is higher.
<u>⇒ Option B is correct</u> because higher volatility means evaporating more quickly
<u>⇒ Option C is false</u> because higher volatility means higher pressure. When pressure increases, the surface tension decreases.
<u>⇒ Option D is false</u> because when the volatility is higher, the liquid/gas escape the container, easier, so there will be less resistance.
A Molecule should be it because it is a bond between atoms to make for instance diamonds.
Answer:
Molar mass of calcium is 40,078 g / mol
Explanation:
Molar mass (M) is the ratio of the mass to the mass of the substance and is expressed in grams per mole (g / mol).
The molar mass of a substance corresponds/it is equal to the relative atomic or relative molecular mass with the addition of the unit g/mol.
The relative atomic mass as well as the relative molecular mass are the basis for expressing the molar mass (M), the mass of one mole of a substance.
