What is normal human reaction time?
the measure of how fast products are made in a reaction
What does the term spontaneous mean in chemical reactions?
This is a very fast reaction.
What has no chemical change and keep its own properties and can be separated?
A mixture is a material composed of two or more substances that can be physically separated, where each individual component retains its own properties and no chemical reaction occurs. Examples of mixtures include saltwater, air, and trail mix.
What is chemical reaction physical reaction?
A physical change is one in which the chemical composition of the substance does not change. A chemical change is one in which new products are formed with their own unique chemical compositions and properties.
What is the chemical reaction witch allows plants to make their own food?
This chemical process is called photosynthesis.
What happens when a chemical union occurs?
When a chemical union occurs, atoms or molecules combine to form a new substance with different properties than the original materials. This process involves the rearrangement of atoms to create new chemical bonds, resulting in the formation of a new compound. Energy may be released or absorbed during the reaction, depending on the specific chemical bonds being formed or broken.
Do fire flies produce their own light?
Yes, by using a chemical reaction in their tail.
What important process occurs in the chloroplasts?
Photosynthesis occurs in the chloroplasts, where sunlight is converted into chemical energy in the form of glucose. This process is essential for plants to produce their own food and release oxygen into the atmosphere.
What reaction keeps going on its own once it starts?
A chain reaction is a type of reaction that keeps going on its own once it starts due to the products of the reaction continuing to fuel the reaction. Nuclear fission reactions in nuclear power plants and explosions are examples of chain reactions that continue on their own once initiated.
What is the term for an organism that can make its own food by carrying out a chemical reaction inside of its cells?
Autotrophs
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.
How can you make your own glow stick at home?
To make your own glow stick at home, you will need hydrogen peroxide, a fluorescent dye, and a small container. Mix the hydrogen peroxide with the dye in the container, and then seal it tightly. When you shake the container, the chemical reaction between the hydrogen peroxide and the dye will produce a glowing light.
