Answer:
Explanation: a) Reaction is exothermic because heat is released
If temperature is lowered, amount of products is increased,
equilibrium transfers to right
b) If pressure decreases, equilibrium transfers to direction in which amount of gas moles is greater, also in left (reactants)
c) If Oxygen is removed, reaction which produces more oxygen is favoured, also balance changes to reactansts (left)
d) Adding product causes equilibrium transfer to left (reactansts)

Answer:
4.65 L of NH₃ is required for the reaction
Explanation:
2NH₃(g) + H₂SO₄(aq) → (NH₄)₂SO₄(s)
We determine the ammonium sulfate's moles that have been formed.
8.98 g . 1mol / 132.06 g = 0.068 moles
Now, we propose this rule of three:
1 mol of ammonium sulfate can be produced by 2 moles of ammonia
Therefore, 0.068 moles of salt were produced by (0.068 . 29) / 1 = 0.136 moles of NH₃. We apply the Ideal Gases Law, to determine the volume.
Firstly we do unit's conversions:
27.6°C +273 = 300.6 K
547.9 mmHg . 1 atm / 760 mmHg = 0.721 atm
V = ( n . R . T ) / P → (0.136 mol . 0.082 L.atm/mol.K . 300.6K) / 0.721 atm
V = 4.65 L
The answer is B- 124 degrees
Answer:
A scientific question is basically a question that can lead to a hypothesis to help us figure out the observation in science. I hope this helps you
