Answer:
2.8 L
Explanation:
From the question given above, the following data were obtained:
Number of mole (n) = 0.109 mole
Pressure (P) = 0.98 atm
Temperature (T) = 307 K
Gas constant (R) = 0.0821 atm.L/Kmol
Volume (V) =?
The volume of the helium gas can be obtained by using the ideal gas equation as follow:
PV = nRT
0.98 × V = 0.109 × 0.0821 × 307
0.98 × V = 2.7473123
Divide both side by 0.98
V = 2.7473123 / 0.98
V = 2.8 L
Thus, the volume of the helium gas is 2.8 L.

Answer:
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O
Explanation:
Step 1: Write out unbalanced reaction
Fe₂O₃ + H₂SO₄ → Fe₂(SO₄)₃ + H₂O
Step 2: Balance
We need the same number of SO₄²⁻ on each side
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + H₂O
Now we need the same amount of H⁺ on each side
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O
