A chemical reaction can be determined by observing changes in physical properties, such as color, temperature, gas production, or formation of a precipitate. Additionally, chemical tests or instruments can be used to analyze the substances involved before and after the reaction to confirm a chemical change has taken place.
What else can I help you with?
What data will you need to determine whether a chemical reaction occurred?
To determine whether a chemical reaction occurred, you will need data such as changes in temperature, formation of new substances, release of gas, and changes in color or odor.
How can one determine the presence of a precipitate in a chemical reaction?
To determine the presence of a precipitate in a chemical reaction, one can look for the formation of a solid substance that appears cloudy or settles at the bottom of the reaction mixture. This solid substance is called a precipitate and indicates that a chemical reaction has occurred.
If one substance changes color is it a chemical reaction?
Not necessarily. Things sometimes change colors during a chemical reaction, but a color change is not sufficient evidence of a chemical reaction. You can add drink mix to water and the water turns colors, but it is not a chemical reaction, just a mixture.
How can one determine the mole ratio in a chemical reaction?
To determine the mole ratio in a chemical reaction, you can use the coefficients of the balanced chemical equation. The coefficients represent the number of moles of each substance involved in the reaction. By comparing the coefficients of the reactants and products, you can determine the mole ratio between them.
How can one determine the ratio of moles in a chemical reaction?
To determine the ratio of moles in a chemical reaction, you can use the coefficients of the balanced chemical equation. The coefficients represent the number of moles of each substance involved in the reaction. By comparing the coefficients of the reactants and products, you can determine the mole ratio between them.

How does a chemical equation show that a chemical reaction has occurred?
A chemical equation shows that chemical reaction has occurred as new substances have been formed from the reagents. A chemical equation has two sides before reaction and after reaction, if there is any change from the before reaction side to the after reaction side, it indicates that a chemical reaction has just occurred.
What is present after a chemical reaction?
That depends on the chemicals present before the chemical reaction and sometimes the conditions under which the chemical reaction occurred.
If the chemical properties of the substance have not changed has a chemical reaction occurred?
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
When a substance is broken down or combined formingnew substance a has occurred?
A chemical reaction has occurred. In a chemical reaction, the atoms in the substances rearrange to form new substances with different properties than the original substances. This process involves breaking and/or forming chemical bonds.
How does the chemical equation show that a chemical reaction occurred?
When a compound produces.
Is a soluble aspirin fizzing in water a chemical reaction?
Yes. If there is the appearance of a gas (fizzing), then a chemical reaction has occurred.
If one substance changes color is it a chemical reaction?
Not necessarily. Things sometimes change colors during a chemical reaction, but a color change is not sufficient evidence of a chemical reaction. You can add drink mix to water and the water turns colors, but it is not a chemical reaction, just a mixture.
How we know a chemical change has occurred when burning a candle?
Burning is a chemical reaction, an oxydation.
What is the products of a chemical reaction?
The products of a chemical reaction are the substances that are formed as a result of the reaction taking place. These products can be different compounds or elements from the reactants that were present before the reaction occurred.
A chemical reaction has not occurred if the products have?
The same chemical properties as the reactants.
