Answer:
t = 0.426 min
Explanation:
assuming order one for the reaction:
∴ K = 0.0396/s
∴ Ca = 0.292 mol/L
∴ Cao = 0.803 mol/L
⇒ K∫δt = - ∫δCa/Ca
⇒ K*t = Ln (Cao/Ca)
⇒ t = [ Ln (Cao/Ca) ] / K
⇒ t = [ Ln (2.75) ] / (0.0396/s)
⇒ t = ( 1.0116)/(0.0396/s)
⇒ t = 25.545 s = 0.426 min
The main objective of flushing Nitrogen into food packets containing oil and fat products is to avoid rancidity, which results when the oil or fat combines with oxygen and produces an unpleasant odour and taste. As a result, flushing Nitrogen creates an unreactive environment, which prevents rancidity.
Answer:
Theanswer to your question is:
Limiting reactant = FeCl₃
Excess reactant = 1.66 g of Mg
Explanation:
Data
Mg = 41 g = 24.31 g/mol
FeCl₃ = 175 g = 162.2 g/mol
3Mg(s) + 2FeCl₃(s) → 3MgCl₂(s) + 2Fe(s)
3(24.31) of Mg ------------------ 2(162.2) of FeCl₃
72.93 g of Mg ------------------ 324.4 g of FeCl₃
Theoretical Proportion = 324.4/72.93 = 4.44
Practical proportion = 175 / 41 = 4.2
As the proportion disminishes the limiting reactant is FeCl₃.
Excess reactant
72.93 g of Mg ------------------ 324.4 g of FeCl₃
x ------------------------- 175 g of FeCl₃
x = (175 x 72.93) / 324.4
x = 39.34 g of Mg
Excess = 41 - 39.34
= 1.66 g of Mg
