Answer:

50 gram of MgS contains =21.56 gram of Mg

Explanation:

Molecular mass of MgS is 56.37 g/mol.

Atomic mass of 1 mole Mg is 24.305

Therefore 56.37 gram of MgS contains 24.305 gram of Mg

                  1   gram of MgS contains \frac{24.305}{56.37} gram of Mg

                  50 gram of MgS contains  \frac{24.305}{56.37}  ×50 gram of Mg

                                                             =21.56 gram of Mg

Tails of phospholipids that don't like water
densk [106]
Those tails are called hydrophobic. You can note the etymology: hydro= water, phobi = fear, aversion, dislike.

Phospholipds' tail is a long non polar chain, made of Carbon and Hydorgens, that rejects water (a polar solvent) and is attracted to non-polar compounds (oil for example).  That is why that tails can atract dirt.

When naming a compound made from a metal and a non-metal, what is done to the name of the second element?
RoseWind [281]
Metals combine with nonmetals to give ionic compounds. When naming binary ionic compounds, name the cation first (specifying the charge, if necessary), then the nonmetal anion (element stem + -ide). Hope this helps!
