PFAS consist of chains of carbon and fluorine atoms linked together. It’s one of the strongest chemical bonds known. “It's these strong carbon-fluorine bonds that make PFAS so durable but also make ...

Students explore the concept that chemical reactions involve the breaking of bonds between atoms in the reactants, and the rearrangement and rebonding of these atoms to make the products. Students ...

The willingness of the 4f orbitals of lanthanide metals to participate in chemical reactions is as rare as their presence in ...

Researchers at the University of Bayreuth have found a way to make plastics more sustainable by utilizing sulfur waste from ...

If they collide with enough energy, bonds can break and new bonds can form in a chemical reaction. The reactants just sit there until energy is added with the flame. The added energy is enough to make ...

Bond breaking is an endothermic process. The opposite is true if we want to make new bonds. Energy is released when new chemical bonds are formed, so bond making is an exothermic process.

The overall change in energy is the difference between the energy of the reactants and products. Energy is transferred when chemical bonds are broken or are formed. Breaking bonds requires energy ...

DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the ...
