Following reactions show the major product,
a) figure describe ionization energy , electron affinity & electron negativity
b) figure describe Atomic Radius
c) does represent anything
Electronegativity : An atom attracted the bond pair of electrons in a covalent bond is called electronegativity of an element. H-->Cl
Ionization energy : The amount of energy is required to remove of an electron from an isolated gas atom is called Ionization energy. M + IP-----> M+ + e-
Electron affinity: The amount of enery is released when an electron added to an isolated atom is called electron affinity.
X + e- ------> X- =- EA
Atomic radius ; The distance between the center of neuclies and outer most shell is called atomic radius.
Answer:
t = 71.3 s
Explanation:
Hello there!
In this case, since the second-order integrated law is given by the following equation:
![\frac{1}{[H_2O_2]} =\frac{1}{[H_2O_2]_0}+kt](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5BH_2O_2%5D%7D%20%3D%5Cfrac%7B1%7D%7B%5BH_2O_2%5D_0%7D%2Bkt)
Thus, given the initial and final concentration of hydrogen peroxide and the rate constant, we obtain the following time:
![\frac{1}{[0.0170M]}-\frac{1}{0.0800M}=0.650M^{-1}s^{-1}t\\\\t=\frac{46.32M^{-1}}{0.650M^{-1}s^{-1}} \\\\t=71.3s](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5B0.0170M%5D%7D-%5Cfrac%7B1%7D%7B0.0800M%7D%3D0.650M%5E%7B-1%7Ds%5E%7B-1%7Dt%5C%5C%5C%5Ct%3D%5Cfrac%7B46.32M%5E%7B-1%7D%7D%7B0.650M%5E%7B-1%7Ds%5E%7B-1%7D%7D%20%5C%5C%5C%5Ct%3D71.3s)

Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. ... Solids, liquids and gases all expand when heat is added.
Answer 1) It is incorrect.
Explanation : For the statement;
Thomson did experiments with cathode ray tubes to show that all atoms contain tiny negatively charged subatomic particles called as electrons<span>.
So the statement should be like this:
AFTER the </span><span>Thomson’s experiments, scientists accepted that the atom was made up of smaller particles.
Answer 2) This is correct.
Explanation : Rutherford was the scientist who discovered that atoms has volume is because of the empty spaces inside it. He did the gold foil experiments to prove this and he was successful in doing this by concluding that tiny dense empty places are occupied by positively charged nucleus.
Answer 3) This is Correct.
Explanation : After Thomson and Rutherford, Millikan also performed an experiment to prove that an atom contains a small positively charged nucleus which is usually surrounded by negatively charged electrons by his oil drop experiment.</span>
