Answer:
48.67 seconds
Explanation:
From;
1/[A] = kt + 1/[A]o
[A] = concentration at time t
t= time taken
k= rate constant
[A]o = initial concentration
Since [A] =[A]o - 0.75[A]o
[A] = 0.056 M - 0.042 M
[A] = 0.014 M
1/0.014 = (1.1t) + 1/0.056
71.4 - 17.86 = 1.1t
53.54 = 1.1t
t= 53.54/1.1
t= 48.67 seconds
Hence,it takes 48.67 seconds to decompose.
Mixture is the right answer

Looking at the formula, each mol of P4O10 contains 4 mol of P, so
(58.5 mol P4O10) x (4 mol P/ 1 mol P4O10) = 234 mol
The full ionic chemical balanced equation for CuCl2 and (NH4)2SO4 is 2(NH4)Cl + CuSO4.
Explanation:
The full ionic chemical balanced equation for CuCl2 and (NH4)2SO4 is
CuCl2 + (NH4)2SO4 ⇔ 2(NH4)Cl + CuSO4.
Here the left side one's are reactants i.e.,CuCl2 and (NH4)2SO4.
The right siders are products i.e.,(NH4)Cl and CuSO4.
The complete ionic equation is used to include both chemical species as well as spectator ions. It is used to indicate which of the reactants and products in the equation exists primarily as ions in aqueous solution.
It is nothing but a chemical equation in which electrolytes which are soluble in water are formed as dissociated ions.
The above chemical reaction is double displacement reaction.
