For example, when you combine hydrogen atoms with oxygen atoms, it makes a whole new type of molecule that you may know: water!]]> 2020-11-16 14:56:48 UTC https://padlet.com/msroquescience/mlacbazgped8ipbd/wish/927426948 msroquescience https://padlet.com/msroquescience/mlacbazgped8ipbd/wish/927428642 When two or more molecules interact and the molecules change, it is called a chemical reaction. This means that the bonds between atoms are broken and new bonds are formed. Because breaking bonds makes energy and it takes energy to make new bonds, energy is either released or absorbed in a chemical reaction. ]]> 2020-11-16 14:57:08 UTC https://padlet.com/msroquescience/mlacbazgped8ipbd/wish/927428642 msroquescience https://padlet.com/msroquescience/mlacbazgped8ipbd/wish/927449731 Mass is neither created nor destroyed in chemical reactions.
