N2 - nitrogen gas - is gaseous at "room temperature". Nitrogen is about 80% of our atmosphere.
K2S, potassium sulfide, is a solid.
C8H18, or CH3(CH2)6CH3, is octane, a liquid component of gasoline.
H2O is water, a liquid at room temperature. (Unless you are an Eskimo.)
CaF2, Calcium Fluorate, is a solid called "fluorospar".

Write formulas for the following compounds phosphorus disulfide?
PS2 is the compound for that name. P= phosphorus S=sulfide and the 2 translates to a di.
What is the formula of calcium fluoride?
The reason it becomes stable is because Ca has 2 valence electrons that it wants to get rid of to become stable. F has 7 valence electrons and wants 1 more to become stable. So, TWO F atoms each take 1 of the 2 electrons from Ca. They form an ionic bond as Ca^2+ and 2F^- to make CaF2.
What is the name of the compound ionic bond of calcium and fluorine?
CaF2, Calcium Fluoride. It is useful in iron smelting
How many moles are there in 12.8 g of calcium fluoride?
12.8 grams Calcium fluoride (1 mole CaF2/78.08 grams) = 0.163 moles CaF2
What is the lattice constant of calcium fluoride?
a=5.462 for CaF2

What is the mass of 0.06 mole of CaF2?
1 mole CaF2 = 78.074g CaF2 0.06mol CaF2 x 78.074g CaF2/mol CaF2 = 5g CaF2 (rounded to 1 significant figure)
For CaF2 Ksp equals 3.9 x 1011 at 25C What is the solubility of CaF2 at this temperature?
The solubility of CaF2 can be determined by taking the square root of its Ksp value. Therefore, the solubility of CaF2 at 25°C is approximately 6.25 x 10^-6 mol/L.
What is the name for the ionic compound caf2?
The name for the ionic compound CaF2 is calcium fluoride.
What has an enthalpy change that is numerically opposite to the lattice energy of CaF2?
The enthalpy change of the formation of CaF2 from its elements (Ca(s) + F2(g) -> CaF2(s)) has an enthalpy that is numerically opposite to the lattice energy of CaF2, which means it requires energy input rather than releasing energy. This is because breaking the bonds in CaF2 and pulling the ions apart in the lattice requires energy, resulting in a positive enthalpy change.
What is the scientific name for fluorite?
The scientific name for fluorite is calcium fluoride (CaF2).
