Overuse of the same chemicals can result in the pest becoming immune to the pesticides.
Explanation:
TO calculate emperical formula , we need percentage composition of the elements and molecular mass of a specific compound which is already given in the question
then create a table with 1.name of element, 2.percentage given and its atomic mass , 3.no. of moles
( %given/at.mass of element) ... then take the least value in the no. of moles you have found now and divide with each no. of moles value .. to get a simple digit number.
You have got the empirical formula
HA +BOH→BA+H2O
neutralisation reaction for monobasic acid monoacidic base
The gas propellant will move "from a region of high pressure to a region of a lower pressure." Furthermore, the gas propellant is important in spray cans because it initiates movement of the fluid inside the can. When sprayed, the fluid will then disperse to a designated target.
Chemical properties can only be tested if you change the substance
