Answer:
It is the energy the ions absorb when they form a crystalline compound.
Explanation:
Lattice energy is the energy released upon the formation of a crystal lattice structure.
Answer:
Mass by mass
Explanation:
Because it's telling only about mass in grams
Answer:
The calculated density will be larger
Explanation:
The calculated density will be <u>larger</u>. Because, the volume is taken accurately, by the water displacement method. But, when we the took the mass, the water was present on the unknown solid. So, the mass of that water was added to the original mass of the solid. Hence, the mass measured was larger than the original mass. We, know from the formula of density that density is directly proportional to the mass of the object.
Density = Mass/Volume
Hence, the larger measured mass means the larger value of density.
