Pollution as a result of lawn fertilizer runoff would be difficult to track and regulate due to the possible breadth of the area affected. Toxins can be spread throughout the land area as well as be carried downstream if near a water source. Sewer systems, rivers, lakes, ponds, etc. can all be negatively affected by lawn fertilizer runoff. Irrigation or rain water can carry toxins for many miles before the effects are detected. Tracing the source of the toxins would be difficult, especially in a highly populated area.
Electronegativity is a measure of the ability of an atom to attract the electrons when the atom is part of a compound. Electronegativity values generally increase from left to right across the periodic table. The highest electronegativity value is for fluorine.
For example, friction between our shoes and the floor stop us from slipping and friction between tyres and the road stop cars from skidding. Friction is sometimes unhelpful. For example, if you don't lubricate your bike regularly with oil, the friction in the chain and axles increases.
Conjugate base contains one less proton as compared to it's parent acid. Deprotonation occurs from most acidic region.
Propionic acid deprotonates to produce it's strong conjugate base propionate.
In propionic acid, -OH group in -COOH functional moiety dissociates to produce . Because the O-H bond electrons remains highly polarized towards oxygen atom due to electron withdrawing inductive effect as well as resonating effect of -COOH moiety.
