A chemical reaction involves the making and breaking of strong chemical bonds.
Explanation: Chemical reactions are characterized by the formation of new substances, and the making and breaking of strong chemical bonds. In practice it is usually fairly easy to discriminate between a chemical change, new substances formed, and a phase change, where bonds may have been broken but no new substances formed.
Examples of chemical reactivity where chemical bonds are manifestly formed include hydrocarbon combustion, the which drives our industrial society, and in which

Substances are changed into different substances when bonds break and form during?
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
Are polymers formed by chemical changes?
yes, they have chemical bonds therefore chemical change is used
How the chemical stability of a mineral is affected by the bonding of the atoms in a mineral?
the chemical stability of minerals is depedent on the strength of the chemical bonds between atoms in the mineral.
What is valence orbital?
A valence electron, also known as valence orbital, is basically composed of electron and atoms that can make a chemical bond. Valence electrons identify other elementÕs chemical properties to determine if the element may bond with other elements.
The scale used to test the relative bond strength between atoms is called the?
Usually a temperature scale is used to test the relative bond strength between atoms. The temperature required to break the bonds determines the bond strength.
Is chemical bond a substance?
No
When does a chemical bond occur?
no a substance is occurring
How can a type of bond determine the volatility of a substance?
A stronger chemical bond (such as a covalent or ionic bond) forms a more stable substance; a weaker bond (such as a dipole or hydrogen bond) forms a more volatile substance.
What substance is formed when elements combine chemically?
a chemical bond
What type of chemical bond causes a substance to have a very high melting point?
an ionic bond
A is a force that holds together atoms in a substance?
chemical bond holds together the atoms in a substance
What is the energy required to break a chemical bond and form neutral isolated atoms called?
The energy required to break a chemical bond and form neutral isolated atoms is called bond energy.
What type of chemical bond when a substance is dissolved in water absorbs energy from the surrounding water?
ionic bond
What is a chemical bond that helps control the pH of a solution?
I suppose that you think to a buffer, not bond.
Consider a substance that is made of molecules that are stable when dry in the presence of water the molecules separate what type of chemical bond holds the substance together when dry?
An ionic bond.
When elements chemically bond together new substance are siml?
When elements chemically bond together a new chemical is produced
Why do elements stick together when they form chemical bonds?
A chemical bond requires energy to break it, therefore if the bond is strong enough then the atoms "stick" together
