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.
I believe the answer would be 2 because, assuming the substance is water, at 50 degrees Celsius it whole be liquid, 100 degrees celsius is its boiling point and at 150 degrees Celsius water is steam.
Hello,
The answer is option A "<span>the heat from the stove".
Reason:
The answer is option A because the variable the heat from the stove is causing the ice to change into water. Its not option B because thats not in the procedures. Its not option C because it is not a variable. Its also not D because thats also not a variable.
If you need anymore help feel free to ask me!
Hope this helps!
