If you start with 4.0 grams of sodium flouride (naf), how many grams of magnesium flouride (mgf2) will be produced? the molar mass of naf is 42g/mole and the molar mass of mgf2 is 62g/mole.

0.09 moles of sodium sulfate in 12 ml of solution

Identify the missing numbers below to show the result of multiplying the numbers (1.6 × 10-19)(5.0 × 106) = c × 10d

Click the button that shows the correct relationship of the electron affinities of the elements sodium and phosphorus. sodium’s electron affinity value is more negative than the electron affinity value of phosphorus. phosphorus’ electron affinity value is more negative than the electron affinity value of sodium. this information cannot be determined using the periodic table. answer is b on e2020.
