Solid, Liquid, Gas & Aqueous. State symbols are written after each formula in chemical equations to show which physical state each substance is in. Brackets are used and they are not usually subscripted although you may come across them written in this way. Aqueous should remind you of the word 'aqua' and means the substance is dissolved in water.
Aug 20, 2023 · We will include a superscripted “o” in the enthalpy change symbol to designate standard state. Since the usual (but not technically standard) temperature is 298.15 K, this temperature will be assumed unless some other temperature is specified. Thus, the symbol is used to indicate an enthalpy change for a process occurring under these ...

Jun 19, 2020 · Figure 2.1.1 2.1. 1: States of Matter. All three containers contain a substance with the same mass, but the substances are in different states. In the left-hand container, the substance is a gas, which has spread to fill its container. It takes both the shape and volume of the container. In the middle container, the substance is a liquid, which ...

Nov 21, 2017 · So its state symbol will be $\text{(aq)}$. Hydrogen on the other hand is a gas (at room temperature and above) and highly insoluble in water: it will leave the reaction as gas and its state symbol will be $\text{(g)}$. So without knowing the physical/chemical properties of the reagents/reaction products, the state symbols cannot be determined.
Mar 7, 2018 · the symbol for a solution in which water is the solvent; in the past this symbol has sometimes been used to denote an infinitely dilute aqueous solution, but infinite dilution should henceforward be denoted by the extra symbol (see paragraph 2.2 and Note b).
