Study figure 8-1. when the ionic compound KI is dissolved in water, the I- ions are pulled into the solution by the attraction b
etween A.the K+ and I- ions.
B. The K + ion and the negative end of the water molecule.
C.the I- ion and the negative end of a water molecule
D. The I- ion and the positive end of a water molecule
PLEASE HELP
The best and most correct answer among the choices provided by your question is the second choice or letter B "<span>The K + ion and the negative end of the water molecule."
</span>First you may remember a tip:
<span>Like dissolves like. This means </span>
<span>polar solvents will get polar and ionic substances dissolved and </span>
<span>non-polar solvents will dissolve non-polar substances. </span>
<span>In KI Potassium K is +vely charged and Iodie I is _negatively charged. </span>
<span>In water H-O-H, Hydrogen is +vely charged and Oxygen is -negatively charged. </span>
<span>Polar ends of water attract opposite ions of KI (or any other ionic or polar substance) thus the ionic compound will dissociate and will be dissolved.</span>

Copper has an atomic number of 29, so it contains 29 protons and 29 electrons. ... The atomic weight of copper is 64; it has 29 protons and 35 neutrons.
This means that the four substances, even they are used in different areas like gardening, plastics or pots, all of them change the endocrine system in humans because they imitate the natural hormones and the body stops to produce them or starts to produce more hormones than the body needs.
They are correlate with some illness like cancer, thyroid problems and infertility.
A valid Lewis structure of IF3 cannot be drawn without violating the octet rule.
Answer: IF3 (Iodine Trifluoride)
This is because, I (Iodine) and F (Fluorine) both have odd number of valence electrons (7) which also means that there are too many valence electrons in the valence shell.
