Answer:
Bromine.
Explanation:
There is more nuclear charge on bromine because in bromine, there are 35 number of protons and 46 number of neutrons while in selenium, there are 34 number of protons and 45 number of neutrons. The atomic size of selenium is larger because they have lower nuclear charge as compared to bromine and we know that when we go to the left of periodic table atomic size increases which attract the electrons towards itself so the shell comes close to the nucleus and decrease occurs in atomic radius.

Answer:
538L of carbon dioxide will be produced
Explanation:
This is a classic example of combustion of an alkane.
If balanced equation is not given; this format can come in handy.
For any alkane of the type : CₙH₂ₙ₊₂ , it's combustion reaction will follow:
2CₙH₂ₙ₊₂ + (3n+1) O₂ → (2n)CO₂ + 2(n+1) H₂O
For ethane:
2C₂H₆(g) + 7O₂(g) → 4CO₂(g) + 6H₂O(l)
Here, 2 mole of ethane gives 4 moles of CO₂.
or, of ethane gives of CO₂.
Then, 269L of ethane will give:
=
= L
= 538 L
Therefore, 538L of carbon dioxide will be produced
