Answer:
A. boiling point
Explanation:
The correct answer is;
A. boiling point
The boiling point of a liquid is the temperature at which the vapour pressure is equal to the atmospheric pressure.
B. melting point
This option is wrong because the melting point is the temperature at which a solid undergoes a phase change to a liquid.
C. freezing point
This option is wrong because the freezing point is the temperature at which a liquid undergoes a phase change to a solid.
The alkaline earth metals (the second group) because their ion charge is +2
Answer:
1-Octanol
Explanation:
Count the amount of carbon atoms in the chain. Nomenclature includes the position of the largest functional group position in the molecule.
In this case the carbon chain has 8 carbon atoms and one hydroxide functional group (OH)
1 (hydroxide is listed first in the carbon chain) - Oct(8 carbons) + anol (Alkanol hydrocarbon with a hydroxide group, use anol suffix )
= 1 - Octanol
Answer:
the answer is 3.33⋅1023 molecules of Cl2. Note that 6.022⋅1023 is also known as Avogadro's number, and it can be referred to as the number of molecules in one mole of that substance. Also, I calculated 70.9 because 35.45 g/mol (the mass of one Chlorine atom) times 2 is 70.9 g/mol (Cl2 has two Chlorine atoms).
