Answer:
The energetic particles coming from the Sun and Saturn's environment allow complex chemistry, such as formation of hydrocarbons and nitriles. The particles also generate a permanent haze around the satellite, rains of methane, winds, seasons Recently, lakes of hydrocarbons seem to have been detected on Titan's surface
Explanation:
Answer:
4
Explanation:
1 is correct
Liquids have no definite shape as they take up the shape of the container. Thus, we can say a liquid has no shape of its own but rather has the shape of the container in which it is filled.
2 is correct
When the atmospheric temperature is increased, it also will increase the boiling point of the liquid
3 is correct
This is an extension of the statement 2. While we decrease the atmospheric pressure, we are also decreasing the boiling point
4 is incorrect
A liquid have a definite volume. When we say a volume is definite, it means the volume is fixed and does not change. The volume of liquids is definite for a particular mass of the liquid and does not change
Answer:
B. The Shell
Explanation:
The shell covers and surrounds whats inside. It protects it!
Answer: The number of molecules in a 45.6 gram sample of
are
.
Explanation:
Given: Mass of
= 45.6 g
Molar mass of
is 28.05 g/mol.
Therefore, number of moles of
are calculated as follows.

According to the mole concept, 1 mole of every substance contains
molecules. Hence, number of molecules present in 1.62 mol are calculated as follows.

Thus, we can conclude that the number of molecules in a 45.6 gram sample of
are
.
