Many chemical equations also include phase labels for the substances: (s) for solid, (ℓ) for liquid, (g) for gas, and (aq) for aqueous (i.e., dissolved in water). Special conditions, such as temperature, may also be listed above the arrow. For example, 2NaHCO3 (s) − →−200°C Na2CO3 (s) +CO2(g) +H2O(ℓ) Key Takeaways How do you Write a Chemical Equation? - A Plus Topper 1. To balance Y on both sides, multiply RHS by 2, i.e., X + Y 2 2XY. Now, the number of atoms of Y is balanced but not the number of atoms of X. Therefore, multiply X on the LHS by 2. Thus, the equation becomes. 2X + Y 2 2XY. This is a balanced equation as the number of atoms of X and Y on both sides is equal.
