maxonik [38]

Answer:

Bohr's model

Explanation:

Rutherford's experimental evidence best supports the Bohr's model. Recall that in the Bohr's model, the Rutherford model was regarded as a fundamental stepping stone.

Experimental evidence from the Bohr's model shows that the atom is not a sphere of positive charges in which negative charges were embedded. It would have been impossible for Neils Bohr to build the quantum theory from such a model.

Hence, the nuclear theory of Rutherford provided a fundamental stepping stone and experimental backup for the Bohr's model of the atom.

All other models mentioned in task 1 (Dalton, Thompson and Bohr) all mention the fact that the atom is made of particles. Thompson effectively described the particles as negative and positive in nature. Bohr took the idea further by proposing that the negative particles (electrons) were actually found in energy levels that are quantized.

A substance has a molecular formula of C8H10N4O2
Nutka1998 [239]

The empirical formula of a substance = C₄H₅N₂O

<h3>Further explanation  </h3>

The empirical formula is the smallest comparison of atoms of compound forming elements.  

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

<em>(empirical formula) n = molecular formula  </em>

((empirical formula)n=C₈H₁₀N₄O₂

divide by 2 :

(C₄H₅N₂O)₂=C₈H₁₀N₄O₂
