When zinc and hydrochloric acid are combined, the following conclusions can be drawn about the chemical reaction taking place:
1. **The mass of the products is exactly the same as the mass of the reactants** - This statement is true according to the law of conservation of mass, which states that mass is neither created nor destroyed in a chemical reaction. It is important to note that while the mass is conserved, the individual components may change their form.
2. **One new product formed is gas** - This statement is true. The reaction between zinc (Zn) and hydrochloric acid (HCl) produces zinc chloride (ZnCl2) and hydrogen gas (H2). The hydrogen gas is released as a byproduct, confirming this statement.
3. **Molecules are changing into different molecules** - This statement is also true. During the reaction, the reactant molecules (Zinc and Hydrochloric acid) are transforming into different product molecules (Zinc Chloride and Hydrogen gas).
4. **Atoms are changing into different atoms** - This statement is false. In a chemical reaction, atoms are rearranged to form new substances, but they do not change into different types of atoms. The total number of each type of atom remains the same before and after the reaction.
So, the conclusions that can be circled are:
- The mass of the products is exactly the same as the mass of the reactants.
- One new product formed is gas.
- Molecules are changing into different molecules.

Yes, I am confident in the assessment provided. Here’s a brief clarification of each point regarding the reaction of zinc and hydrochloric acid:
1. **The mass of the products is exactly the same as the mass of the reactants** - This is true due to the law of conservation of mass. The total mass remains constant, meaning that the mass of the reactants (zinc and hydrochloric acid) will equal the mass of the products (zinc chloride and hydrogen gas).
2. **One new product formed is gas** - This is true. The reaction produces hydrogen gas (H₂) as a byproduct, which is released as bubbles during the reaction.
3. **Molecules are changing into different molecules** - This statement is true. The reactants (molecules of zinc and molecules of hydrochloric acid) recombine to form new molecules (zinc chloride and hydrogen gas).
4. **Atoms are changing into different atoms** - This is false. The atoms themselves are not changing; they are simply rearranging to form new substances. Zinc atoms stay as zinc atoms, and hydrogen atoms remain as hydrogen atoms, but are restructured into different molecular forms.
Therefore, you should circle the first three statements as correct conclusions about the reaction taking place. The last statement should not be circled. If you have any more questions or need further clarification, feel free to ask!
