Item SC066005: When two white powders react to form a yellow powder, the yellow powder is made up of the same kinds of atoms as the white powders, but the atoms are combined into different molecules.
Two white powders were mixed together. A chemical reaction occurred, and a yellow powder was formed. What is the relationship between the yellow powder and the white powders?
- The yellow powder is made up of the same kinds of atoms as the white powders, but the atoms are combined into different molecules.
- The yellow powder is made up of the same kinds of molecules as the white powders, but the molecules are a different color.
- The yellow powder was released from inside the atoms of the white powders.
