Answer:
d
Explanation:
the moon because moon is following the earth
Answer:
The answer is diagram D.
When the solutions dissolve in an aqueous solution they dissociate to form ions
That's
AgNO3 → Ag+ NO3-
NaCl → Na+ Cl-
Upon mixing Ag+ pairs with Cl- and Na+ pairs with NO3 -
That's we have
AgCl and NaNO3
I hope this helps you.
Good luck
The Nuclear Model-1909. Ernest Rutherford's great contribution to atomic theory was to show what happens to an element during radioactive decay. This enabled him to construct the first nuclear model of the atom, a cornerstone of present-day physics The Nuclear Model-1909.
Lewis Structure of
Oxygen Difluoride is sketched as....
Step 1: Calculate the
total number of valence electrons present in OF₂. This is done by adding all valence electrons of each element. i.e...
Valence e⁻s of Oxygen = 6
Valence e⁻s of Fluorine-1 = 7
Valence e⁻s of Fluorine-2 = 7
------------
Total Valence e⁻s
20Step 2: Draw central element (O) in center surrounded by fluorine atoms. Now, sketch a single bonds between O and both F atoms. Now, subtract 2 electrons per single bond from total valence electrons.. i.e..
Total Valence e⁻s = 20
2 single bonds (2 × 2) = 4
-----------
16Now, distribute remaining 16 electrons on each element to complete its
octet starting from most electronegative element.
Lewis structure of OF₂ is as follow,
