To determine whether the ending substance is the same as the blue powder, we need to analyze the repeating groups of atoms provided for both the blue powder and the ending substance. Unfortunately, you haven't displayed the specific repeating groups of atoms in your question, so I'll outline the general approach to answer your questions.
-
Is the ending substance the same substance as the blue powder?
To answer this, we need to compare the chemical structure and repeating group of atoms of the blue powder to that of the ending substance. If the repeating group of atoms for the ending substance is identical to that of the blue powder, then they are the same substance. If they differ, then they are different substances, indicating a chemical change occurred when they were mixed.
-
What happened to the atoms of the starting substances when the ending substances formed?
During a chemical reaction, atoms from the reactants (the blue powder and colorless liquid) are rearranged to form the products (the resulting substances after mixing).
- If the blue powder's repeating group remains unchanged in the ending substance, it indicates that the blue powder has not reacted and simply exists alongside the other product.
- If the blue powder's structure changes in the resulting substance, it suggests that a chemical change occurred in which the atoms from the blue powder interacted with those of the colorless liquid to form a new compound.
- Atoms are conserved in a chemical reaction, so the total number of each type of atom before the reaction will equal the total number after the reaction, although they may be bonded together differently.
With more specific information about the repeating groups of atoms, we could reach a definitive conclusion regarding the identity of the ending substances and the nature of the interaction between the initial substances.
