Complex reactions that rely on both breaking and forming chemical bonds often need an external energy input to start but are then self-sustaining. For example, the combustion of hydrocarbons requires a heat source to break the first few bonds. Typically, materials containing hydrocarbons, such as ...
Chemical bonds: solder, flux and solvent cements are what make pipe joints stand the test of time.Deerr, Allison
Chemical bonds are bundles of electric forces that hold atoms and molecules together. Chemistry involves several different kinds of bonds. For example, the hydrogen bond is a relatively weak attraction involving a hydrogen-bearing molecule, such as water. The hydrogen bond accounts for the shape of...
Re:What does Enthalpy mean? « Reply #1 on: August 06, 2005, 08:29:49 AM » enthalpy is the change in energy level of the reactants in the specified reaction/process.bond-breaking has a positive enthalpy as energy is taken in to break the bonds. bond-making has a negative enthalp...
Chemical Bonds:Chemical bonds are long lived attractions between atoms that lead to the formation of chemical compounds. Chemical bonds can be either ionic or covalent.Answer and Explanation: Chemical bonds are the energy storage mechanism for the human body. The breaking of carbon to hydro...
the label on my saline solution does not mention it, therefore I wonder if that isn’t the reason why it doesn’t work. is there something else I can use instead? i was hoping to avoid borax Thx Pingback: How To Make Earth Day Slime Recipe Ideas for Homemade Slime Pingback: Unicorn...
is unstable and hydrolyzes into ADP and phosphate. This is because the P-O-P bond in ATP is weaker than the formed phosphate bonds, and the reaction releases energy through hydrogen bonding between the products and water, resulting in an exothermic and spontaneous reaction. In the chemical ...
A molecule is a group of two or more atoms joined by chemical bonds, whereas a compound is a substance formed by the chemical bonding of more than one type of element that exists in a fixed proportion.

What are chemical bonds made of? Electrons shared between atoms Molecules that are attracted to each other by orthostatic tension A sugar-phosphate backbone I don't remember! I'd like to review this topic. Neutrinos shared between atoms
