Answer : The energy produced from the combustion of 5 mole 
is 
Solution : Given,
Released energy = 803 KJ
The balanced combustion reaction is,
As per the question,
1 mole of releases energy = 803 KJ
5 mole of produced energy = 
Therefore, the energy produced from the combustion of 5 mole is
The last option is correct
Answer:
The complete question is as follows
Given the incomplete equation: 2 N2O5(g) ==> Which set of products completes and balances the incomplete equation?
A)2 N2(g) + 3 H2(g)
B)2 N2(g) + 2 O2(g)
C)4 NO2(g) + O2(g)
D)4 NO(g) + SO2(g)
The correct option is C) 4NO2(g) + O2(g)
Explanation:
Note that the products should be NO2 and O2 since the reactant is entirely made up of N and O. option A is not correct as hydrogen cannot emerge as a product in this reaction. Matter can never be created or be destroyed bu can only change in a chemical reaction. Option D is not also correct for the same reason.
Option B is not correct since it did not balance the number of atoms of O and N in the reactant side of the equation.
The option C) 4NO2(g) + O2(g) is therefore the right option since it balances both the elements and the number of atoms of the elements present.
Answer:
CoOH3 and LiBr.
Explanation:
CoBr3 + LiOH reacts into CoOH3 and LiBr. Swap each cation in each compound and balance them.
