Explain the difference between rotation and revolution.
Then use these terms to explain how Earth, the moon,
and the Sun move relative to one another.

Rotation: spins on its axis

Revolution: travels around another object

Explanation:

The Earth rotates on its axis, while it revolves around the sun.

The moon revolves around the Earth.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
