A chemical equation is used in the means of writing out and describing a chemical reaction, such as the reactants and the substance that forms after the reaction (called the product)
P.S: it took me a little to find out the question since i had it too. Some teachers decide to give out questions like these in attempt to get people to practice their research skills instead of just relying on a "magic book" for the answer.
What else can I help you with?
How can you tell when a chemical has reacted?
You can tell when a chemical reaction has occurred by observing changes in color, temperature, formation of a gas, or the formation of a precipitate. Additionally, a chemical reaction often involves the breaking and forming of bonds between atoms, resulting in the rearrangement of molecules.
How can one tell how much reactant will be used in a reaction?
from a balanced chemical equation
How do you tell how fast a chemical reaction will take?
Only after the measurement of the reaction rate. See the link below for details.
What does the coieffecient in a chemical equation tell you?
The number of that type particle involved in the reaction.
How you can tell if a mixture is a chemical reaction?
a mixture is by definition not a chemical reactionA mixture is two or more substances which have been combined such that each substance retains its own chemical identity.So a mixture cannot be a chemical reaction, signs of a chemical reaction include:colour changeprecipitation (formation of a solid)effervescence (giving off gas)And every single chemical reaction involves gives of some heat.
What will tell you the efficiency of a chemical reaction?
You need to calculate the yield of the reaction.
How can you tell the difference between a chemical reaction and not a chemical reaction?
A chemical reaction will do the following; Change colour Create smoke A non chemical reaction (Physical Reaction) will do the following; Change State Be able to change back to the original materials
What can chemical equations tell you about a chemical reactions?
Chemical equations describe the products and reactants in a chemical reaction.
How can you tell there is a chemical reaction when iron rusts?
Because it is not a physical change it is a chemical change.
How can you tell when a chemical has reacted?
You can tell when a chemical reaction has occurred by observing changes in color, temperature, formation of a gas, or the formation of a precipitate. Additionally, a chemical reaction often involves the breaking and forming of bonds between atoms, resulting in the rearrangement of molecules.
How can you tell fools gold from gold by using a chemical reaction?
With magnets.
How can you tell a chemical reaction is losing heat?
The apparatus becomes hot.
How can one tell how much reactant will be used in a reaction?
from a balanced chemical equation
How do you tell how fast a chemical reaction will take?
Only after the measurement of the reaction rate. See the link below for details.
What does the coieffecient in a chemical equation tell you?
The number of that type particle involved in the reaction.
Chemical properties tell you how something?
Chemical properties describe how a substance behaves in a chemical reaction, such as its reactivity, ability to react with other substances, and changes in composition. These properties are determined by the substance's chemical composition and structure.
How you can tell if a mixture is a chemical reaction?
a mixture is by definition not a chemical reactionA mixture is two or more substances which have been combined such that each substance retains its own chemical identity.So a mixture cannot be a chemical reaction, signs of a chemical reaction include:colour changeprecipitation (formation of a solid)effervescence (giving off gas)And every single chemical reaction involves gives of some heat.
