High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
Using the VSPER theory, the effect of lone pairs on molecular shape can be discussed.
There are 3 types of electron pairs present in a molecular shape: bond pair -bond pair, lone pair - bond pair, lone pair - lone pair.
Strength of repulsions between these three types of pair follows the order:
lone pair- lone pair > lone pair - bond pair > bond pair - bond pair
Whenever there is an addition of lone pairs to the geometry, some distortions take place which decreases the bond angles and some asymmetry is attained in the original molecular shape.
<u>Answer:</u>
<em>The molarity of the
solution is
</em>
<em></em>
<u>Explanation:</u>
The Balanced chemical equation is

Mole ratio of
: KCl is 1 : 1
So moles
= moles KCl





So Molarity


= 0.000402M or mol/L is the Answer
(Or)
is the Answer
Answer:
Lewis structure is shown in the image below.
Explanation:
Acetate ion (CH₃COO⁻)
Valence electrons of carbon = 4
Valence electrons of oxygen = 6
Valence electrons of hydrogen = 1
Charge = 1 (Negative which means that the electrons are being added)
The total number of the valence electrons = 2(4) + 2(6) + 3(1) + 1 = 24
The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete. So,
The Lewis structure is shown in the image below.
