i mean state symbols for the equation:
2Mg + O2 = 2MgO
Mg is a solid, O2 is a gas, and MgO is a solid (but smoke comes from the reaction, but the ash you see is in fact a solid).
Ah, I see you're interested in the state symbols for the equation! Here it goes:
2Mg(s) + O2(g) = 2MgO(s)
In this balanced equation, (s) indicates that magnesium (Mg) and magnesium oxide (MgO) are in solid state, while (g) represents oxygen (O2) in its gaseous state. So remember, when in doubt, just think of a gassy oxygen flying around and solid magnesium staying in place!
The state symbols for the equation 2Mg + O2 = 2MgO are as follows:
2Mg (s) + O2 (g) = 2MgO (s)
Here, (s) represents a solid state, and (g) represents a gaseous state.
To determine the state symbols for the equation:
2Mg + O2 = 2MgO
State symbols are used to represent the physical states of the reactants and products in a chemical equation. They indicate whether a substance is a solid (s), liquid (l), gas (g), or an aqueous solution (aq) in the given reaction.
In this case, we can determine the state symbols based on our knowledge of the elements and their common physical states.
- 2Mg: Magnesium (Mg) is a solid at room temperature, so we can indicate it with (s) for solid.
- O2: Oxygen (O2) is a gas at room temperature and is diatomic (comes as O2 molecules), so we can indicate it with (g) for gas.
- 2MgO: Magnesium Oxide (MgO) is a solid at room temperature, so we can indicate it with (s) for solid.
Therefore, the state symbols for the given equation would be:
2Mg (s) + O2 (g) = 2MgO (s)
