Final Answer:
Battery acid (H₂SO₄) is a compound composed of molecules. The numbers in the chemical formula represent subscripts, indicating the ratio of atoms in a molecule rather than coefficients in a chemical reaction.
Step-by-step explanation:
Battery acid, represented by the chemical formula H₂SO₄, is a compound. Compounds are substances composed of two or more different elements chemically bonded in fixed ratios. In the case of H₂SO₄, hydrogen (H), sulfur (S), and oxygen (O) combine to form a molecule. The numbers (subscripts) in the chemical formula indicate the ratio of atoms in a single molecule. Specifically, H₂SO₄ means there are two hydrogen atoms, one sulfur atom, and four oxygen atoms in each molecule of battery acid.
The subscripts are crucial for understanding the composition of the compound on a molecular level. In this context, the subscripts provide information about the number of each type of atom present in a single molecule of battery acid. It is important to distinguish subscripts from coefficients in a chemical reaction. While subscripts indicate the number of atoms in a molecule, coefficients in a chemical reaction represent the number of molecules participating in the reaction.
In summary, battery acid (H₂SO₄) is a molecular compound, and the subscripts in its chemical formula specify the proportion of each element within a single molecule of the compound. Understanding these molecular details is essential for grasping the composition and properties of substances in the field of chemistry.
