1. since Beatrice is applying force to the box, she is doing work
2. formula is work = force x displacement
3. displacement = 2 meters, force = 40 N
work = 40 x 2 = 80 Joules
Answer:
The concentration of SO₂ will decreases
Explanation:
As you can see in the reaction
2 moles of gas ⇆ 3 moles of gas
Based on Le Châtelier's principle, a change doing in a system will produce that the system reacts in order to counteract the change made.
If the pressure is increased, the system will shift to the left in order to produce less moles of gas and decrease, thus, the pressure.
As the system shift to the left, the concentration of SO₂ will decreases
<h3>
Answer:</h3>
H₂O
<h3>
Explanation:</h3>
The additional product that balances the reaction is water (H₂O).
- Therefore, the complete balanced equation for the reaction is;
H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + H₂O(l)
- Balancing a chemical equation ensures that the law of conservation of mass is obeyed by the reaction.
- The reaction is an example of a neutralization reaction where an acid, H₂SO₄, reacts with a base, NaOH to form a salt and water.
- In this case the salt formed is sodium sulfate (Na₂SO₄)
