The student repeated the investigation. The student used solutions that had different concentrations from the first
investigation
The student found that 15.5 cm of 0.500 mol/dm dilute sulfuric acid completely
reacted with 25.0 cmn of potassium hydroxide solution.
The equation for the reaction is:
2KOH + H2SO. - K SO4 + 2H2O
Calculate the concentration of the potassium hydroxide solution in mol/dmand in
gidimº
Relative atomic masses (A): H = 1
O = 16
K= 39

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary

i think the answer is terrae but not 100 percent sure. ▓▬▬ §

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
