The dark smooth areas on the surface of the moon is called Maria.
Maria is made up of solidified lava which is a result of volcanic activity on the moon.
When Galileo observed these smooth dark spots on the moon he called them 'mare' which is latin for 'sea'. And the plural form of mare is 'maria'. Unlike Galileo predictions, recent investigations confirm that maria are not oceans but solidified lava.

Answer:
- Water's temperature will be in equilibrium with the surrounding temperature.
- Closed system.
Explanation:
Hello,
In this case, in thermodynamics we define a sealed room as a closed system (matter neither leaves nor enters to the system) which allows the energy transfer as it is not isolated. In such a way, as time goes by, the water will exchange energy with the surroundings in order to attain the thermal equilibrium (equal temperature for both water and surroundings). Thus, if the surroundings are hotter than the cold water, it will heat up until equilibrium temperature. Moreover, if the surroundings are colder than the water, it will cool down until equilibrium temperature.
Best regards.
Answer:
The same 45.98 g of NaCl will be produced since 2 moles of Na will react with 2 moles of NaCl. Hence the stoichiometric coefficient will be in a ratio of 1:1
