Are chemical reactions a chemical change of original substances before a chemical reaction takes a place?
Chemical reactions involve the breaking and forming of chemical bonds in the original substances, resulting in a chemical change. Before a chemical reaction occurs, the original substances have specific chemical properties that undergo transformation during the reaction. The reactants interact to form new products with different chemical compositions.
How are these last two chemical reactions alike different?
The question is quite vague, as there are many chemical reactions and none are specified, so the two chemical reactions must be specified before an answer can be given.
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.
What is another solvent used instead of ethanol and why?
Water is a tremendous solvent. It is referred to as a universal solvent. Most chemical reactions involve a solution in water. This is because many chemical separate into positive and negative ions in water. When this occurs with more than chemical, it results in a chemical reaction where the ions recombine into other chemicals that weren't there before.
What chemical reactions are in hockey?
Chemical reactions in hockey mainly involve energy transformations. For example, when a player eats carbohydrates before a game, they undergo cellular respiration to convert them into energy for muscle movement. Additionally, the ice surface undergoes a phase change from solid to liquid when players skate over it due to friction, creating a thin layer of water.
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.

Does chemical reactions make new materials called the reactants?
Hi there! Well, to answer your question, chemical reactions invlove two sets of substances: the reactants and the products. The reactants are the chemicals that are involved BEFORE the reactions occurs. The products are the chemicals that are formed as a result of the chemical reaction. In another words, the products are your end results. Therefore, chemicals reactions make new materials called the PRODUCTS, rather than reactants. For example in photosynthesis: Glucose + Oxygen -----> Carbon dioxide + Water Glucose and oxygen are your reactants, whereas carbon dioxide and water are your products.
Does wood undergo a physical change before it burns?
No. It is a chemical change.
Is food spoiling a chemical change?
Yes, it is a chemical change. It only takes one experience with a rotten egg to learn that they smell different that fresh eggs. When eggs and food spoil, they undergo a chemical change. The change in odor is a clue to the chemical change Chemical Reactions Chemical Changes are also called Chemical Reactions. Chemical reactions involve combining different substances. The chemical reaction produces a new substance with new and different physical and chemical properties. Matter is never destroyed or created in chemical reactions. The particles of one substance are rearranged to form a new substance. The same number of particles that exist before the reaction exist after the reaction.
What important physical change must fats undergo before chemical change can take place?
Fats must undergo melting or dissolving to break down into smaller molecules for chemical changes to take place. This physical change allows the fat molecules to interact more readily with other substances during chemical reactions.
What are the chemicals on the left side of the arrow called?
In a chemical reaction equation, anything to the left of the "yield" arrow is considered a reactant. These are the substances you have before the reaction begins; you can think of them as "ingredients." When the reaction ends, you no longer have any reactants, you have products.
Do chemical reactions produce new atoms?
No, chemical reactions do not produce new atoms. Atoms are rearranged in chemical reactions to form new substances, but the number of atoms remains constant before and after the reaction. This is known as the Law of Conservation of Mass.
How are these last two chemical reactions alike different?
The question is quite vague, as there are many chemical reactions and none are specified, so the two chemical reactions must be specified before an answer can be given.
What is the Es complex?
The ES complex refers to the enzyme-substrate complex formed when an enzyme binds to its substrate. This complex is a temporary intermediate state in enzymatic reactions before the substrate is converted to products. In the ES complex, the enzyme provides a suitable environment for the substrate to undergo specific chemical reactions.
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.
