What else can I help you with?
When substances chemically combine what do they do?
A chemical reaction occur: the transfer of electrons between elements is involved.
Which parts of the atoms interact in a chemical reaction?
In a chemical reaction, it is the outer electrons of atoms that interact with each other. These outer electrons are involved in forming chemical bonds between atoms, which ultimately results in the formation of new substances.
How do the substances that form in a chemical reaction differ from the substances that react?
The substances that form in a chemical reaction are the products, while the substances that react are the reactants. Products have different chemical properties than reactants because they have undergone a chemical change during the reaction.
Are chemical changes when substances combine or are they when substances breaking apart?
A reaction between two substances or the decomposition of a substance are chemical changes.
What type of chemical reaction occurs when electrons are shared?
no chemical reaction takes place . when electrons are shared it is known as covalent bond
What are two ways that chemical reaction between substances affect chemical bonds?
3j
What is the difference between a chemical reaction and a product in a chemical equation?
The reactants are the substances that undergo the chemical reaction, and are shown on the left side of a chemical equation. The products are produced by the chemical reaction, and are shown on the right side of the chemical equation.
What is the relationship between a redox pair and the transfer of electrons in a chemical reaction?
In a redox pair, one substance loses electrons (oxidation) while the other gains electrons (reduction). This transfer of electrons between the pair drives the chemical reaction.
In terms of chemical bonds and electrons what kinds of changes occur between atoms when substances undergo chemical reactions?
Bonds are broken by rearrangement of electrons, and then new bonds are made, again by rearrangement (sharing, donating, etc) of electrons.
How does a chemical equation express relationships between substances?
The chemical equation is a graphic expression of a chemical reaction.
What is is a result of a chemical reaction?
Chemical change.
What is a process that changes one or more new substances?
A chemical reaction is a process that changes one or more substances into new substances with different chemical properties. This involves the breaking and formation of chemical bonds between atoms or molecules.
