4FeS₂ + 11O₂ → 2Fe₂O₃ +8SO₂
What happen if FeS₂ is added to the reaction is that
The reaction will shift in the direction of the products
<u><em>Explanation</em></u>
- FeS₂ is a reactant in reaction above .
- When more of reactant added to a system at equilibrium, it increases the concentration of reactant molecules.
- According to collision theory,this increase the number of collisions per second of reactant molecule and therefore more product is formed.
Answer: C
Explanation:
Velocity is displacement over change in time. It’s a vector quantity, so velocity must include direction. You’re changing the direction, but the speed stays the same, because you are still going 20 km per hr
A phase change is a physical change.
Hope this helps!
