   What are state symbols GCSE chemistry?

   • State symbols are shown in subscript, just like when we use numbers to show how many atoms are in a molecule such as diatomic oxygen (O₂). There are four state symbols to learn for GCSE chemistry: Three of these symbols should be familiar as they are the common states of matter – solids, liquids and gases. Read on to find out what aqueous means.

   What do state symbols mean in chemistry?

   • State symbols are used to show the physical state of reactants and products in a reaction, at the reaction temperature. This means the temperature at which the reaction takes place. State symbols are shown in subscript, just like when we use numbers to show how many atoms are in a molecule such as diatomic oxygen (O₂).

   Which state symbols should be included in a chemical equation?

   • The four state symbols show the physical state of substances at normal conditions Symbol equations should be included when writing chemical equations. CuCO3 (s) + 2HCl (aq) ⟶ CuCl2 (aq) + CO2 (g) + H2O (l) Be careful when writing the state symbol of solutions of liquids.

   Which state symbol is used when a reaction takes place at room temperature?

   • MgO(s) + H₂SO₄(aq) → MgSO₄(aq) + H₂O(l) Water is always given the state symbol (l) when a reaction takes place at room temperature. The reaction temperature determines the state and so the following rules will help you to understand which state symbols to use: When the reaction temperature is below the melting point, the substance is a solid.

   4) Gases expand to fill the size and shape of their containers. They tend to have relatively low density levels. Examples include: oxygen and nitrogen. 5) Plasmas are ionized (electrically charged) gases that possess an equal number of positive and negative charges, examples include fluorescent lighting and the sun.

   State symbols. 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
