The electrical conductivities of the following 0.100 m solutions were measured in an apparatus that contained a light bulb as the indicator of conductivity. rank the solutions in order of decreasing intensity (brightest to dimmest) of the light bulb.

rank from brightest to dimmest bulb. to rank items as equivalent, overlap them.

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

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.
