In each of the molecules drawn below one chemical bond is colored red. decide whether this bond is likely to be polar or not. if the bond is likely to be polar, write down the chemical symbol for the atom which will have more negative charge. oco the highlighted bond is polar and the more negative atom is the highlighted bond is nonpolar. nhhh the highlighted bond is polar and the more negative atom is the highlighted bond is nonpolar. clf the highlighted bond is polar and the more negative atom is the highlighted bond is nonpolar.

explanation:

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
