During setting of materials like concrete or plaster, the bonds that are broken are water molecules, which are used in the hydration process to form new chemical bonds. These new bonds include the formation of calcium silicate hydrate (C-S-H) gel in concrete and gypsum crystals in plaster, which give the material its strength and durability.

Which bonds are affected during blow drying and setting?
Hydrogen bonds in the hair are temporarily broken by heat during blow drying and setting. When the hair cools down, the hydrogen bonds reform in the new shape, helping to set the hair in the desired style.
What bonds are broken during the combustion of methane CH4 to form water and carbon dioxide?
During the combustion of methane (CH4) to form water (H2O) and carbon dioxide (CO2), the bonds broken are the carbon-hydrogen (C-H) bonds in methane and the oxygen-oxygen (O=O) bonds in molecular oxygen (O2). These bonds are broken to form new bonds between carbon and oxygen in CO2, and hydrogen and oxygen in H2O.
Is ionic or covalent broken and formed in chemical reactions?
During chemical reactions bonds are broken.
What gets broken during chemical reactions?
chemical bonds between atoms
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 bonds are broken during the combustion of methane (CH4) form water and carbon dioxide?
All four C-H bonds in methane are broken during combustion.
What must be broken for the DNA strand to separate?
Hydrogen bonds between the nitrogenous bases need to be broken for the DNA strand to separate during replication or transcription.
What bonds are broken during the combustion of methane CH4 to form water and carbon dioxide?
During the combustion of methane (CH4) to form water (H2O) and carbon dioxide (CO2), the bonds broken are the carbon-hydrogen (C-H) bonds in methane and the oxygen-oxygen (O=O) bonds in molecular oxygen (O2). These bonds are broken to form new bonds between carbon and oxygen in CO2, and hydrogen and oxygen in H2O.
Is ionic or covalent broken and formed in chemical reactions?
During chemical reactions bonds are broken.
What bonds are broken in order the unzip the DNA strands?
The hydrogen bonds are broken in order to unzip the DNA strand. This all occurs during the DNA replication process.
Which bonds in hair are broken during styling?
The hydrogen bonds in hair are the ones primarily broken during styling. When hair is exposed to heat from styling tools, such as flat irons or curling irons, the hydrogen bonds weaken and allow the hair to be reshaped into a new style.
What bonds are broken during combustion of methane to form water and carbon dioxide?
the bond broken are C-H bonds (in methane) and O-O bonds (in oxygen) The reaction is :- CH4 +2O2 -> CO2 + 2H2O
What type of bonds are broken during the unwinding stage of replication?
hydrogen in bases
What gets broken during chemical reactions?

What happens to the bonds of the products during a chemical reaction?
Chemical reactions always involve changes in the chemical bonds that join atoms in compounds. At least one chemical bond is broken or formed during a chemical reaction.
