The two chemical compounds are not the same, because their ratio is not equal. In both samples the composition of lead and oxygen is different.
<h3>
What is a chemical compound?</h3>
A chemical compound is a substance made of numerous similar molecules (or molecular entities) joined by chemical bonds and comprising atoms from various chemical elements. Therefore, a molecule made up of only one type of atom is not a compound. Chemical reactions, which may entail interactions with other molecules, can change a compound into a distinct substance. Atomic bonds may be broken or new ones created during this process.
<h3>
What are the calculations?</h3>
sample 1 = mass of lead / mass of oxygen = 12.92g/2g = 6.46 .
sample 2 = mass of lead/ mass of oxygen = 34.27 - 14.39/14.39 = 1.38 .
so, the ratios are not the same.
Hence, the two chemical compounds are not the same, because their ratio is not equal. In both samples the composition of lead and oxygen is different.

Sn^2+ + Br2 ---> Sn^4+ + 2Br^- is referred to as a non-spontaneous redox reaction.
<h3>What is a Non spontaneous reaction?</h3>
This type of reaction doesn't favor the formation of the product and must be endothermic.
In the reaction above under the given conditions, ΔG is positive and it is intended to form Sn(s) and Br(l) through the reduction of tin cation to make bromine liquid and tin solid. This therefore points to the direction of the reaction being non-spontaneous one.

Answer is: John Dalton proposed that matter is made of tiny particles.
Proust's law or law of constant composition said that a given chemical compound always contains its component elements in fixed ratio and does not depend on method of preparation.
Water (H₂O) is made of two hydrogen atoms and one oxygen atom:
m(H) : m(O) = 2·1 : 16 = 1: 8.
Dalton said that matter is composed of atoms and atoms of different elements can join to form chemical compound.
Answer:
La intuición es un conocimiento que surge sin seguir el camino racional para su construcción y formulación, y por lo tanto no puede explicarse o incluso, y a veces ni verbalizarse. La persona puede relacionar ese conocimiento o información con experiencias previas, pero por lo general es incapaz de explicar por qué llega a esa conclusión. Las intuiciones suelen presentarse más como reacciones emotivas repentinas, latidas, veintes que nos caen, sensaciones, imágenes, frases o palabras que irrumpen a nuestra conciencia, más que como pensamientos elaborados.
Buda decía que “la intuición y no la razón atesora la clave de las verdades fundament

Intuition is a knowledge that arises without following the rational path for its construction and formulation, and therefore can not be explained or even, and sometimes not verbalized. The person can relate that knowledge or information to previous experiences, but usually is unable to explain why he reaches that conclusion. Intuitions tend to be more like sudden emotional reactions, beats, twenties that fall, sensations, images, phrases or words that burst into our consciousness, rather than elaborate thoughts.
Buddha said that "intuition and not reason treasures the key of fundamental truths"
