Answer:
15.17 g
Explanation:
To answer this, we need to find the molar mass of nickel in nickel (II) fluoride. The formula for nickel (II) fluoride is NiF2. This gives us the molar mass of 96.69 g. The mass percentage of nickel is 60.70% approximately (as we divide the molar mass of nickel by that of nickel (II) fluoride), and 60% of 25g gives us 15.17 g
Lipids are much denser than water so they often " float " on water and also because that lipids and water can not dissolve to form a solution. lipids always tend to remain at top of water since they are denser .
That would be the waxing and waning crescents.
Hope it helps!
According to the principle, electrons fill orbitals starting at the lowest available energy states before filling higher states (e.g., 1s before 2s). The Madelung energy ordering rule: Order in which orbitals are arranged by increasing energy according to the Madelung Rule.
