The lab procedure mentions that not all of the oxone may dissolve after being added to the water because the water may be satura
ollegr [7]

Answer:

The answer is (C) There are more solute molecules than water molecules.

Explanation:

A saturated solution is one in which no more solute can be dissolved or disintegrated into the solvent. When or if the ozone  stops being dissolved in the water, it implies that the water has already taken on more ozone molecules than it can contain, meaning there are more solute molecules (ozone molecules) than there are solvent molecules (water molecules).

No' of molecules divide by avogadro number , 6×6.023×10^23 so (2.2×10^22)÷(6.023×10^23)
= 0.03653 moles
moles × Molar mass = mass
n×Mr=m
0.03653×40 = 1.46 grams

Lithium and fluorine undergo ionic bonding. Using the noble gas electron configurations for each (below), please explain the pro
Slav-nsk [51]

Answer:

Lithium loses one electron to fluorine and forms ionic bond, having formula LiF.

Explanation:

Lithium is the element of the group 1 and period 2 which means that the valence electronic configuration is [He]2s^1.

Fluorine is the element of the group 17 and period 2 which means that the valence electronic configuration is [He]2s^22p^5.

<u>Thus, lithium loses 1 electron and become positively charged. Fluorine on the other hand accepts this electron and become negatively charged.</u> This is done in order that the octet of the atoms are complete.  <u>These both ions then form ionic bond as their will be electrostatic interaction between the two oppositely charged ions.</u>

Thus, the formula of calcium chloride is LiF.
