Jenna buys 12 lb of meat. some of the meat is chicken and costs $1.90/lb. the rest is beef, which costs $4.30/lb. she spends a total of $34.80
which equation models this situation?
let c represent the number of pounds of chicken she buys.
a. (1.9 + 4.3)(12 – c) = 34.8
b. 4.3c + 1.9(c + 14) = 34.8
c. 4.3c + 1.9(12) = 34.8
d. 1.9c + 4.3(12 − c) = 34.8

step-by-step explanation:

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.
