i think it's I 
I was confused by IV then search on gg and it said ZnSO4 should be Zn2SO4 instead but still im not sure Zn2SO4 is real 
 
        
             
        
        
        
Answer:
38 : 25
Explanation:
First thing's first, we have to confirm if the reaction is indeed balanced.
The equation of the reaction is given as;
C25H52 + 38 O2 → 25 CO2 + 26 H2O
From the reaction, 38 moles of O2 produces 25 moles of CO2
The ratio is given as;
38 : 25
 
        
             
        
        
        
Answer:
Approximately 100 °C.
Explanation:
Hello,
In this case, since the entropy of vaporization is computed in terms of the heat of vaporization and the temperature as:

We can solve for the temperature as follows:

Thus, with the proper units, we obtain:

Hence, answer is approximately 100 °C.
Best regards.
 
        
             
        
        
        
Answer:
Fe is limiting, and it will produce .0188 mols of Fe2O3
Explanation:
after you convert both Fe and O2 to mols by using their molar mass, you see there is less Fe than O2 so that is your limiting reactant. To find the amount of Fe2O3 you devide the limiting reactant by it's coefeciant (4) then multiply it by the products coefficant (2). Let me know if you have any questions
