Answer:
The empirical formula of this question is :
C.
Explanation:
The empirical formula is the simplest whole number ratio of elements in the chemical formula of the molecule.
It is calculated using:
n = The common factor
The Molecular formula represents the exact composition of the elements in the compound.
For example :
Molecular formula : C4H8O2
<em>Find the common factor n ?</em>
<em>here , 2 is common factor(which is divisible by 4 ,8,2)</em>
divide each element by 2
generally 1 is not written
C2H4O is the empirical formula
In this question , the molecular formula C40H56
n = common factor = 8(It is divisible by 40 , 56 )
So, correct option is<u> C</u>
Answer: C) 8 moles
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
According to stoichiometry of the given balanced equation:
2 moles of decomposes to form 2 moles of
Thus 8 moles of decomposes to form= of
Thus 8 moles of are produced from 8 moles of
