Answer:
Mgf2 Bond type
Therefore, one Mg2+ needs two F– ions to balance. The 2+ of the Mg is balanced by having two -1 charged ions. Therefore, the formula of the compound is MgF2. The subscript two indicates that there are two fluorines that are ionically bonded to magnesium.

Answer:
The heat of vaporization of the gold sample is 1577.397 joules per gram.
Explanation:
The latent heat of vaporization of gold (), in kilojoules per gram, is the heat required by a unit mass of gold to transform the material from liquid to gas:
(1)
Where:
- Energy required for vaporization, in joules.
- Mass, in grams.
If we know that and , then the heat of vaporization of the gold sample is:
The heat of vaporization of the gold sample is 1577.397 joules per gram.
Daughter cells are identical after mitosis because they have a copy of the chromosome. Not sure if this helped though

All eukaryotic cells have a cell surface membrane (aka plasma membrane). It is very fragile. its role is to hold the cell together and to help control what substances can get in and out. (It is partially permeable) allowing only some substances to pass through it.
The answer should be 0.78
