A1-l sample of co initially at stp is heated to 546 k, and its volume is increased to 2 l.(a) what effect do these changes have on the number of collisions of the molecules of the gas per unit area of the container wall? (b) what is the effect on the average kinetic energy of the molecules? (c) what is the effect on the root mean square speed of the molecules?

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.

answer is 33
