Low-surface-energy substrates such as polypropylene are notoriously difficult to effectively bond, with most hot melt adhesive formulations unable to spread across their surface and form chemical bonds. For more information about the difficulties of chemical bonding, read our blog post on physical and...
The basis of all chemical reactions is the breaking of bonds, or decomposition, and the creation of bonds, or synthesis. Decomposition requires energy because the chemical bonds are initially stable, and energy is required to break them apart. The molecules in the bond have a lower energy level...
The exothermic reactions are those reactions where heat is produced. The opposite of exothermic reaction is an endothermic reaction where heat is absorbed.Answer and Explanation: In an exothermic reaction, the total energy of the reactants has more energy than the total energy of the products, ...
ai● Digestion is the process whereby large complex,aiiinsoluble food molecules are broken down I hydrolysedinto simpler, soluble and diffusible molecules that canbe absorbed into the body cells.●There are two types of digestion, chemical digestionwhere it involves breaking down chemical bonds within...
Chemical bonds are the forces that hold the atoms together in a molecule: These forces are of various types. So, one can have metallic bonds, ionic bonds, and covalent bonds. The strengths of the bonds are different and...
By selectively increasing the translational, rotational, and vibrational energies and by controlling the relative orientation of the reaction partners with tunable infrared and UV lasers, direct insight can be gained into the molecular course of the breaking and re-forming of chemical bonds. Examples ...
Household bleaches are a part of everyday life and are in nearly every American home, usually in more than one form. Butwhat is bleach? Bleach is a very useful chemical both around the house and for large-scale use. You can use bleach toremove stainson clothing or to whiten your laundr...
It's like roadies breaking down the stage in an arena after a major band has been through town. The cell shrinks and sends out distress signals, which are answered by vacuum cleaners known as macrophages. The macrophages clean away the shrunken cells, leaving no trace, so these cells have...
This molecule can be broken into the ions H+ and OH– by breaking one of the O-H bonds. In chemical bonds, electrons of different atoms interact, but their nuclei (the plural of nucleus) remain intact. This is because the force holding the protons and neutrons together is extremely ...
In chemistry, chemical changes are represented by chemical equations. These chemical equations contain the reactants on the left-hand side of the reaction arrow and products on the right-hand side of the reaction arrow. For a chemical change to occur, chemic...
