Answer: Keith and Aaron only

Explanation:

Since the school record for the 100-meter dash is 18 seconds, while

Juan did 19 seconds;

Hans did 16 seconds;

Keith did 17 seconds; and

Aaron did ILELE (unknown value)

Based on this illustration, only Keith and Aaron finished the 100-meter race at a lesser time than the school record.

Thus, Keith and Aaron only are the students that have broken the school record.

The solubility of magnesium phosphate at a given temperature is 0.173 g/L. Calculate the Ksp at this temperature. After you calc

jek_recluse [69]

Answer: $K_{sp}=1.25\times 10^{-14}$

$pK_{sp}=13.90$

Explanation:

Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as $K_{sp}$

The equation for the ionization of magnesium phosphate is given as:

$Mg_3(PO_4)_2\rightarrow 3Mg^{2+}+2PO_4^{3-}$

When the solubility of $Mg_3(PO_4)_2$ is S moles/liter, then the solubility of $Mg^{2+}$ will be 3S moles\liter and solubility of $PO_4^{3-}$ will be 2S moles/liter.
