What is the molecular formula of a compound with the empirical formula
ipn [44]

Answer:  C_2H_2O_2

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

The empirical formula is CHO

The empirical weight of CHO = 1(12)+1(1)+1(16)= 29 g.

The molecular weight = 60 g/mole

Now we have to calculate the molecular formula:

n=\frac{\text{Molecular weight}}{\text{Equivalent weight}}=\frac{60}{29}=2

The molecular formula will be=2\times CHO=C_2H_2O_2

Thus molecular formula will be C_2H_2O_2

Masteriza [31]

Answer:

B. electrons and protons.

Explanation:

In an electrically neutral atom of any element, there are equal number of protons and electrons in the atom.

Protons are the positively charged particles in an atom.

Electrons are the negatively charged particles within the atom.

  When the number of protons and electrons are the same or equal, the atom is neutral.

But when there is an imbalance, an ion results.
