The correct answer is
<span>B. An attraction between the positive end of one molecule and the negative end of another.
Because the dipole is the molecule that has </span> the positive end and the negative end,
Answer:
using three significant figures, to match the data
v = 51.4
p = -0.999
Answer:
d) Make it flexible
Step-by-step explanation:
Raw hides dry out to form a hard material that can decay with an offensive smell when they become wet.
Tanning converts the protein of the raw hide into a stable material that will stay flexible and not decompose when it gets wet.
a) is <em>wrong</em>. The purpose of tanning is to soften the leather.
b) is <em>wrong</em>. You smooth the leather manually with fine sandpaper.
c) is <em>wrong</em>. Tanning does not impart water resistance. It prevents the leather from putrefying when it does get wet.
Answer:
E - Be and O
A - Mg and N
E - Li and Br
F - Ba and Cl
B - Rb and O
Explanation:
Be and O
Be is a metal that loses 2 e⁻ to form Be²⁺ and O is a nonmetal that gains 2 e⁻ to form O²⁻. For the ionic compound to be neutral, it must have the form BeO (E-MX).
Mg and N
Mg is a metal that loses 2 e⁻ to form Mg²⁺ and N is a nonmetal that gains 3 e⁻ to form O³⁻. For the ionic compound to be neutral, it must have the form Mg₃N₂ (A-M₃X₂).
Li and Br
Li is a metal that loses 1 e⁻ to form Li⁺ and Br is a nonmetal that gains 1 e⁻ to form Br⁻. For the ionic compound to be neutral, it must have the form LiBr (E-MX).
Ba and Cl
Ba is a metal that loses 2 e⁻ to form Ba²⁺ and Cl is a nonmetal that gains 1 e⁻ to form Cl⁻. For the ionic compound to be neutral, it must have the form BaCl₂ (F-MX₂).
Rb and O
Rb is a metal that loses 1 e⁻ to form Rb⁺ and O is a nonmetal that gains 2 e⁻ to form O²⁻. For the ionic compound to be neutral, it must have the form Rb₂O (B-M₂X).
