A formula unit is the same as the empirical formula of a compound or an ionic molecule. It is the lowest ratio of the atoms in the compound or ion. Zinc acetate ions dissociates into zinc ions and acetate ions. The dissociation reaction is expressed as follows:
Zn(O2CCH3)2 = Zn2+ + 2(O2CCH3)1-
We determine the amount of acetate ions produced as follows:
Moles Zn(O2CCH3)2 = (3 formula units Zn(O2CCH3)2) ( 1 mol / 6.022x10^23 formula units) = 4.98x10^-24 mol Zn(O2CCH3)2
moles (O2CCH3)1- = 4.98x10^-24 mol Zn(O2CCH3)2 ( 2 mol (O2CCH3)1- / 1 mol Zn(O2CCH3)2 ) = 9.96x10^-24 mol (O2CCH3)1-
# of acetate ions = 9.96x10^-24 mol (O2CCH3)1- ( 6.022x10^23 ions / 1 mol (O2CCH3)1-) = 6 acetate ions
Injecting salt crystals over the ocean to grow cloud droplets has been proposed in efforts to make the clouds brighter thereby affecting the radiation budget. The light of the sun shines on Earth, some of that light is reflected by the clouds back to space and some of the light reaches the earth and warms our planet. The earth and the hot oceans emit infrared radiation (IR), which we feel as heat. That IR "light"; returns to space through the atmosphere. Most are trapped by greenhouse gases, which keep the earth warm. Soon after, the IR radiation returns to space. Scientists call this "energy budget of the Earth" this cycle of incoming and outgoing energy.
The correct answer to your question is B, solvent.

Answer:
<h2>4.55 L</h2>
Explanation:
The new volume can be found by using the formula for Boyle's law which is
Since we're finding the new volume
We have
We have the final answer as
<h3>4.55 L</h3>
