Explanation:
The image attached describes the formation of magnesium fluoride.
Magnesium has two valence electrons while fluorine has seven valence electrons. Magnesium can now transfer one electron each to two fluorine atoms thereby forming the compound MgF2.
This has been shown pictorially in the image attached to this answer.
Answer:
13
Explanation:
There are 13 moles O in a mole of Ca5(PO4)3OH because there are 13 oxygen atoms in every molecule of Ca5(PO4)3OH. Convert moles oxygen to number of atoms of oxygen. One mole is 6.022*10^23, so your conversion factor would be 6.022*10^23 atoms O/mol O.
Answer:
maybe the potatoes took a different form? They smell different, look different taste different, etc.
Explanation:
Mg3(PO4)2 - Mg²⁺ forms base
PO4³⁻ forms acid
Ma(OH)2 is a base(Y).
H3PO4 is an acid(X).
3Mg(OH)2 + 2H3PO4 ---> Mg3(PO4)2 + 3H2O
