Explanation:
Hydrogen atoms contain 1 proton and 1 electron while being devoid of neutrons. When they lose their electron they form an ion or H+, a particle carrying a unit of positive charge. pH measures how basic or acidic a water-based solutions are, with a formula for pH is
pH = -log[H+].
...where pH is -base 10 log of the concentration of hydrogen ions within the solution.
Initial volume= 20 mL
Final volume= 600 mL
# of dilutions=
= 30
for a pH 2= [H+]= 
∴ [H+]= 
and pH is an antilog of [H+]= - log 
∴pH = 3.47

Answer:
When a species of mosquito or insect is resistant to any chemical, it is good for the species of the mosquito because it does not kill it, but if it seeks to combat it in crops or in human environments it is dangerous.
Explanation:
Whenever a mosquito or a species is resistant to a chemical, it means that it has an adaptation mechanism so as not to die, as it did before, against that chemical.
