How is Earth's orbit around the Sun similar to the orbits of other planets around the Sun?
Each planet's travels the same distance in it's orbit as the other
planets.
Each planet's orbit is determined by how fast it rotates.
Each planet's orbit takes about the same amount of time.
Each planet's orbit is controlled by the pull of the Sun's gravity.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

it's filtration, but this is an assumption so my apologies if i got this

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

i don't know people like to fight everywhere rip.
