<h2>Hello!</h2>
The answer is:
The empirical formula is the option B.
The empirical formula of a compound is the simplest formula that can be written. On the opposite, the molecular formula involves a variant of the same compound, but it can be also simplified to an empirical formula.
We are looking for a formula that cannot be simplified by dividing the number of molecules/atoms that conforms the compound.
Let's discard option by option in order to find which formula is an empirical formula (cannot be simplified)
A.
It's not an empirical formula, it's a molecular formula since it can be obtained by multiplying the empirical formula of the same compound.
B.
It's an empirical formula since it cannot be obtained by the multiplication of a whole number and the simplest formula. It's the simplest formula that we can find of the compound.
C.
It's not an empirical formula, it's a molecular formula since it can be obtained by multiplying the empirical formula of the same compound.
D.
It's not an empirical formula, it's a molecular formula since it can be obtained by multiplying the empirical formula of the same compound.
Hence, the empirical formula is the option B.
Have a nice day!
Answer: a) : Decomposition
b) : double displacement
c) : Synthesis (Combination)
d) : redox
Explanation:
Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.
A double displacement reaction is one in which exchange of ions take place.
Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.
Redox reaction is a type of chemical reaction in which oxidation and reduction takes place in one single reaction. The oxidation number of one element increases and the oxidation number of other element decreases.
