net ionic equation:
SO₄²⁻ (aq) + Ba²⁺ (aq) → BaSO₄ (s)
Explanation:
We have the following chemical reaction:
H₂SO₄ (aq) + Ba(OH)₂ (aq) → BaSO₄ (s) + 2 H₂O (l)
Now we write the ionic equation:
2 H⁺ (aq) + SO₄²⁻ (aq) + Ba²⁺ (aq) + 2 OH⁻ (aq) → BaSO₄ (s) + 2 H⁺ + 2 OH⁻ (aq)
We remove the spectator ions to obtain the net ionic equation:
SO₄²⁻ (aq) + Ba²⁺ (aq) → BaSO₄ (s)
where we have:
(aq) - aqueous
(s) - solid
(l) - liquid

You would expect snow to fail at the peak or the top because the weather is coldest there.
54 would be the correct answer i beleive
For combustion reaction we need oxygen and the results most of the time produce heat which mean first one is correct.
.500 moles is roughly
.5 * 6.022 * 10^23 = 3.011*10^23 atoms. this is independent of STP
if it’s wrong i’m sorry
