HNO3
Explanation:
Arrhenius acids usually start with H and typically contain an oxygen or halogen.
Answer:
about 310ºC
Explanation:
The Moon is the natural satellite of the Earth.
The Moon orbits around the Earth in approximately 27 days, and its average distance from the Earth is about 380,000 km.
Moreover, the mass of the Moon is
.
The Moon has no water on its surface and no atmosphere: due to the lack of atmosphere, heat coming from Solar radiation is not retained near the surface. Moreover, the Moon orbits around the Earth keeping one face always towards it, so every location on the Moon has 13 consecutive days of daylight followed by 13 days of darkness.
As a result, there is a large thermic excursion between the maximum and minimum temperature on the Moon. In particular, we have:
- Minimum temperature: -173 degrees Celsius
- Maximum temperature: +127 degrees Celsius
So this difference is about

So, about 310ºC.
Something that can be separated by physical means implies that there is a noticeable difference between the two components when mixed together. For example, salt water has a noticeable difference in that the boiling points of water and salt are so different that the water can be separated by evaporation. The only thing that can be separated by physical means is a mixture.
