The symbol o written above a reaction arrow indicates that the reaction is carried out under an oxygen atmosphere.
A triangle symbol in a chemical reaction formula means that there is heat supplied to the reaction. The triangle is typically placed above the arrow between reactants and products. Sometimes the word "heat" is also written above the arrow.
The compound above the arrow in a chemical reaction signifies the catalyst or condition used to facilitate the reaction. It indicates that the reaction requires the presence of that specific compound to proceed or to increase the speed of the reaction.
The symbol that means "produces" in a chemical reaction is an arrow pointing to the right (→). This arrow is used to show the direction in which the reactants are transformed into products during a chemical reaction.
The symbol used in a chemical equation to indicate yields is the arrow "->". This arrow separates the reactants from the products in a chemical reaction.
The symbol for electricity in a chemical reaction is "e-" or "E". It represents the transfer of electrons between reactants in an electrochemical reaction.
Energy is often written above the arrow in chemical reactions to indicate whether a reaction is endothermic (energy is absorbed) or exothermic (energy is released). This notation helps to show the overall energy change during the reaction.
A catalyst is typically written above the arrow in a chemical equation, indicating its role in speeding up the reaction without being consumed itself. It is not listed as a reactant or product in the equation.
A catalyst is written above the arrow in a chemical equation to show that it is not consumed in the reaction and thus does not appear in the overall stoichiometry of the reaction. This means that it does not take part in the reaction as a reactant or a product, but it still helps in speeding up the reaction. Placing it above the arrow helps to distinguish it from other reactants or products.
A triangle symbol in a chemical reaction formula means that there is heat supplied to the reaction. The triangle is typically placed above the arrow between reactants and products. Sometimes the word "heat" is also written above the arrow.
the arrow (--->)
In a decomposition reaction, a triangle or delta symbol (Δ) is often used to indicate that heat is required for the reaction to occur. This symbol is typically placed above or below the reaction arrow. It signifies that the reactants need to be heated in order to break down into simpler products.
The most common way is by substituting the one-way arrow of a normal reaction by a symbol (that can not be formed on this keyboard!) of both left- and right-pointing arrows one above the other. <=>
The compound above the arrow in a chemical reaction signifies the catalyst or condition used to facilitate the reaction. It indicates that the reaction requires the presence of that specific compound to proceed or to increase the speed of the reaction.
This means that the reaction in question takes place in an aqueous solution. Even when water does not take part in a reaction, many things - most things, actually - will be more chemically active if dissolved in water, than in solid form.
The symbol that means "produces" in a chemical reaction is an arrow pointing to the right (→). This arrow is used to show the direction in which the reactants are transformed into products during a chemical reaction.
The symbol used in a chemical equation to indicate yields is the arrow "->". This arrow separates the reactants from the products in a chemical reaction.
The symbol for electricity in a chemical reaction is "e-" or "E". It represents the transfer of electrons between reactants in an electrochemical reaction.
