What happens in a chemical reactions?
the change in the nuclei of the atoms.
What changes do chemical reactions involve in chemical bonds that join atoms in compounds?
The bonds in a molecule can break and atoms can bond with other atoms.
Why is a phase change not a chemical reaction?
Because chemical bonds are not formed or broken by a phase change.
What happens to the atoms within molecules undergoing a chemical reaction?
In a chemical reaction sometimes old bonds are broken and new bonds are formed.
The process in which atoms are rearranged and chemical bonds are broken and formed to produce a chemical change of a substance.?

When old chemical bonds are broken and new ones are formed this is called?
A chemical reaction.
How is a chemical bond usually broken?
Chemical bonds are both formed and broken during chemical reactions. For example, bonds are formed and broken in the synthesis reaction 2H2 + O2 = 2H2O. The bonds in both diatomic oxygen and hydrogen are broken, forming new bonds to form a water molecule.
What is formed or broken in a chemical reaction?
Some bonds between atoms are broken and new bonds are formed.
What is a chemical reaction that harvests energy when chemical bonds are broken?
It always takes energy to break chemical bonds. Similarly, energy is released when bonds are formed. When the new bonds formed are weaker than the old ones broken, the reaction consumes energy and is called endothermic.
How are bonds related to chemical bonds?
Bonds in the reactants are broken, and bonds in the product are formed.
Is ionic or covalent broken and formed in chemical reactions?
During chemical reactions bonds are broken.
In a chemical reaction bonds are broken or?
Chemical reactions can be either endothermic (that is, where bonds broken) or exothermic (i.e. where bonds are formed). The former requires thermal energy input; the latter releases heat energy as bonds are formed.
How energy is made available by chemical reaction?
in chemical reactions, energy is absorbed or released when chemical bonds are broken and new ones are formed.
What happens chemical bonds during a chemical reaction?
Some or all of the existing chemical bonds in the reactants are broken and new chemical bonds are formed in the products.
Scientifically what is a physical change?
A change in which no chemical bonds are broken or formed.
What is a formed or broken apart during a chemical reaction?
chemical bond
What is a substance formed by chemical bonds called?
A chemical molecule
