(3 points) a second order chemical reaction involves the interaction (collision) of one molecule of a substance with one molecule of another substance to produce on molecule of a new substance this is denoted by +→ the rate of this reaction is modeled by the differential equation =−− where is the amount of substance at time and > 0 are the initial amounts of substances and respectively. suppose that 18 moles of substance and 12 moles of substance react together. if =0.022 1/(mol⋅sec) and )=0, find the amount of time until there are 10 moles of substance

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
