Look at the sample work below. x+8=32 x+8+(-8)=32+8 x=40 what error, if any, was made? a. the addition property of equality was not applied correctly. b. the multiplication property of equality was not applied correctly. c. the symmetric property of equality was not applied correctly. d. no errors were made.

I believe that the answer is A. The addition property of equality was not applied correctly.

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.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
