These elements are interrelated steps, so they don't always function in the same order.
Answer:
Mars
Explanation:
neither Mercury nor Venus have any moons at all, Earth has one and Mars has its two small moons
Answer: 8.59 L of oxygen gas are needed to produce 100 kJ of energy at STP
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number
of particles.
Standard condition of temperature (STP) is 273 K and atmospheric pressure is 1 atmosphere respectively.
1 mole of every gas occupy volume at STP = 22.4 L
The balanced chemical reaction is:

3909.9 kJ of of energy is produced by = 
100 kJ of oxygen gas are needed to produce = 
Answer:
km/h
mph
iph
Explanation:
I have no idea what mis or dit could be
km/h is kilometers per hour
mph is miles per hour
I assume iph is inches per hour?
<span>These values also increase from the
bottom to the top of a group because the size of the atom decreases, resulting
in a smaller distance between the nucleus and the valence electron shell, which
increases the attraction between the protons and electrons.</span>
