Answer:
363C
Explanation:
V = KT and T = V/K
3.5=k(35+273) = 308k
k=3.5/308 =0.011
new T=7.0/0.011=636K = 636-273 =363C
The number of chlorine atoms needed would simply be the
ratio of distance and diameter. But first convert 200 pm to mm:
<span>200 pm = 2 E-7 mm </span>
So the number of chlorine atoms needed is:
<span>1.0 mm / (2 E-7 mm) = 5,000,000 Chlorine atoms = 5 E6
atoms</span>
The correct statement is <span>(4) All atoms of a given element must have the same atomic number.
Atoms come in different isotopes(which have different mass), which differ in the number of neutrons, but are still the same element (this tells you why the other options are bad).
