An adult takes 400 mg of ibuprofen. Every 2 hours, the amount of ibuprofen in the person’s system decreases by 29%. a) Write a function that will give the amount of ibuprofen remaining after any amount of time.
b) Use this function to predict the amount of ibuprofen, to the nearest mg, remaining after 12 hours.
c) Find the amount of time, to the nearest tenth of an hour, it will take for half of the ibuprofen to be left in a person’s system.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
