Answer:
repel
Explanation:
When it comes to electrical forces, "opposites charges attract" while "like charges repel."
There are primarily two types of charges: positive charge and negative charge. The forces they exert upon each other will depend on their charges. The<u> positive charge has an </u><em><u>attractive force</u></em><u> to a negative charge.</u> On the contrary,<u> it has a</u><em><u> repulsive force</u></em><u> to the same positive charge</u>. Thus, it will repel each other.
So this means that <em>opposite charges will draw closer together</em> while<em> like charges will move apart from each other.</em>
Answer:
(1). The vapor pressure is 91 mmHg at 20°C.
(2). No, benzene will not boil at sea level.
Explanation:
Benzene, C6H6 is an aromatic, liquid compound with with molar mass of 78.11 g/mol and Melting point of 5.5 °C. One of the importance or the uses of benzene is in the making of fibres and plastics.
The vapour pressure of benzene can be gotten from the table showing the vapor pressure of different liquids.
Boiling point can simply be defined as the point or the temperature in which the vapor pressure is the same with the atmospheric pressure.
The atmospheric pressure is 760mmHg, while the vapor pressure at sea level is at the temperature of 15°C which is equal to 71 mmHg( from the table showing the vapor pressure of different liquids).
71 mmHg is not equal to 760 mmHg, thus, at sea level Benzene will not boil.
