Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. Categorise the given reactions as- combination, decomposition, displacement, double displacement or redox reaction. In order for the two sides to be balanced, we need to put a little more mass on the left side until they are the same mass. The equation is balanced by changing the scalar numbers that precede each part of the equation. The state of matter (aq) stands for aqueous, meaning only the ions are shown in the equation and that they are in the water. 31.
