Question

A chemist mixed two substances together: a colorless liquid with a strong smell and a white solid with no smell. The substances' repeating groups of atoms are shown above on the left. After they were mixed, the chemist analyzed the results and found two substances. One ending substance had the repeating group of atoms shown above on the right. Is the ending substance the same substance as the colorless liquid? What happened to the atoms of the starting substances when the ending substances formed? Be sure to explain your answers to both of these questions.

Answer 1

Answer:

[a]. It is the same substance as the colorless liquid with a strong smell.

[b]. the substance with colorless liquid with a strong smell and a white solid with no smell are being used up to produce the ending substance had the repeating group of atoms shown above on the right and the other ending substance.

Explanation:

Atoms are referred to be the smallest units of a substance although it can be sub-divided into smaller units such as proton, neutron and electron. When atoms combines in group they form a molecule.

From the question above it is seen that two substances were mixed together to give two ending substances that is:

substance A [ colorless liquid with a strong smell] + substance B[white solid with no smell] ---------> substance C[ repeating group of atoms shown above on the right] + substance D.

The ending substance that is, substance C is the same substance as substance A which is the colorless liquid with a strong smell.

When the substance A reacted with substance B, it gives substance C and D that is the ending substances are the products of the reaction between A and B.

Hence, the substance with colorless liquid with a strong smell and a white solid with no smell are being used up to produce the ending substance had the repeating group of atoms shown above on the right and the other ending substance.
