Which element, when combined with phosphorus, would form ionic compound? A) Carbon
B)Oxygen
C)Magnesium
D)Boron

Explanation:

Magnesium Phosphide has a formula of Mg3P2 . In order to bond ionically the charges must be equal and opposite. It will take two -3 phosphide ions to balance two +2 magnesium ions forming a magnesium phosphide molecule of Mg3P2 . I hope this was helpful.

Explanation:

Magnesium is a light silver-white ductile bivalent metallic element; in pure form it burns with brilliant white flame; it occurs naturally only in combination as in magnesite and dolomite and carnallite and spinel and olivine.

Dolomite is a light colored mineral consisting of calcium magnesium carbonate; a source of magnesium; used as a ceramic and as a fertilizer.

So, the final answer is c. magnesium.

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

c is the answer because when something is left after something evaporates that shows the chemical change.
