When writing a chemical equation, an arrow pointing up would indicate that a gas is going to bubble out of the solution. An arrow pointing down indicates that some product will precipitate out of the solution.

∙ 11y agoIn a chemical equation, the arrow means yields. For example: H2CO3----> CO2+H2O. Do you get it?
Wiki User
∙ 11y agoThe up arrow is used on the products side of a reaction to show that a compound is released as a gas.
Wiki User
∙ 11y agoIn the chemical equations the up arrow means the "product is a Gas".

What can you do if you want to either make a chemical reaction happen faster or slower?
to slow down a chemical reaction you use the substance called an inhibitor. to speed up a chemical reaction you use the substance called a catalyst.
What does a catalyst do in a chemical reaction?
Reduces the activation energy of the reaction, which speeds up the progress of the reaction It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.
What function catalyst perform in chemical reaction?
Catalysts speed up the chemical reaction.
What is catalist?
A catalyst is a substance that accelerates a chemical reaction. It does this by lowering the activation energy necessary for that reaction to start. A catalyst is not a reactant or a product, and it does not get used up in a reaction. It is simply present with the reactants and the products and it does not change in a reaction. In an equation, it is correct to show the chemical formula for the catalyst in small characters above the "yield" arrow. The opposite of catalyst is inhibitor.
Start up energy of a chemical reaction?
Energy that starts a chemical reaction is called activation energy
Why is a catalyst written above the arrow in a chemical equation rather than with the reactants?
The enzyme is written above the arrow of the chemical equation because it is involved in the reaction without being changed by it or used up in the reaction. It is not a reactant or a product.
What can a chemical reaction be speeded up by?
A catalyst can speed up a chemical reaction.
What is the arrow read as in chemical equations?
It reads as "Yields." The equation is set up as (reactants) (Yield Sign) (Products).
What can speed up a chemical reaction by decreasing?
chemical reaction
What is chemical reaction in an enzyme?
to speed up a chemical reaction
What can you do if you want to either make a chemical reaction happen faster or slower?
to slow down a chemical reaction you use the substance called an inhibitor. to speed up a chemical reaction you use the substance called a catalyst.
What does a catalyst do in a chemical reaction?
Reduces the activation energy of the reaction, which speeds up the progress of the reaction It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.
What is lowered to speed up a chemical reaction?
Activation energy is lowered to speed up a chemical reaction.
What is the main function to speed up a chemical reaction?
Chemical reactions can be sped up by: 1) Increasing the surface area of reaction. 2) Heating the reaction. 3) Sometimes choosing a different solvent can speed things up. 4) Use of a catalyst.
What speeds up chemical reactions?
to speed up a chemical reaction .. we use a catalyst
By decreasing this you can speed up a chemical reaction?
Decrease the activation energy to speed up a chemical reaction.
What function catalyst perform in chemical reaction?
Catalysts speed up the chemical reaction.
