What is form when two substances are in the same container but no chemical reactions occurs?
What is a change that occurs when one or more substances change into entirely new substances with different properties?
Reversible reactions are those in which the chemical change taking place may be paralleled by another change back to the original substances. The rates at which chemical reactions proceed depend upon various factors, e.g., upon temperature, pressure, and the concentration of the substances involved and, sometimes, upon the use of a chemical called a catalyst.
n oxidation and reduction reaction occurs in both aqueous solutions and in reactions where substances are burned in the presence of oxygen gas, involves a transfer of electrons as the driving force of the chemical reaction. The reactants in these reactions will lose or gain electrons and change their charge as they form the products. The driving force of these chemical changes is electrons transfer.
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 ----->…
A change that occurs when one or more substances change into entirely new substances with different properties is called?
An oxidation reaction occurs when a chemical substance loses electrons to another substance. The substance gaining electrons undergoes a reduction reaction. These types of reactions are called oxidation-reduction reactions, or redox reactions. Oxidation reactions occur when the oxidation state of an atom increases, such as occurs when an atom loses electron(s). A reduction reaction occurs when the oxidation state of an atom is decreased, such as occurs when an atom gains electrons. Not all redox…
That really depends on what kind of chemical reactions you are talking about. If you want to know where metabolism takes place (breaking down sugars into energy), that would be in the mitochondria. Synthesis of proteins occurs on the ribosomes. Degradation of proteins occurs in the lysosomes. Synthesis of DNA and RNA occurs in the nucleus. Each part of the cell is involved in very important chemical reactions.
