Which of the following is most likely to be a gas at room temperature CH4 MgO CaF2 FeCl3 LiF?
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".
What else can I help you with?
What is the lattice constant of calcium fluoride?
The lattice constant of calcium fluoride (CaF2) is approximately 5.462 Å (angstroms).
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
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.
Is CaF2 a covalent compound?
No, CaF2 is an ionic compound. Ionic compounds are typically formed between a metal (like calcium) and a non-metal (like fluorine), resulting in the transfer of electrons from the metal to the non-metal to form ions. In the case of CaF2, calcium (Ca) is a metal and fluorine (F) is a non-metal.
What is the solubility of CaF2 in water and how does it vary with temperature?
The solubility of CaF2 in water increases with temperature. At 25C, the solubility of CaF2 in water is about 0.0016 g/100 mL. As the temperature rises, the solubility also increases.
Is nh3 is a substances is at least likely to be ionic or caf2 or na2o or mgbr2?
NH3 is least likely to be ionic among the compounds mentioned. NH3 is a covalent compound consisting of a single nitrogen atom bonded to three hydrogen atoms. The other compounds - CaF2, Na2O, and MgBr2 - are ionic compounds formed by the transfer of electrons from a metal to a nonmetal.
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?
8.8 x 10-9E.A candle burns, producing light.Rain falls from the sky.
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?
Of these choices:a. Ca(s) + F2(g) → CaF2(s)b. Ca(g) + F2(g) → CaF2(s)c. Ca2+(g) + 2F−(g) → CaF2(s)d. Ca(g) + 2F(g) → CaF2(s)
What is the scientific name for fluorite?
The scientific name for fluorite is calcium fluoride (CaF2).
What is the formula for fluorite?
CaF2.
How many calcium atoms are in CaF2?
In one molecule of CaF2, there is one calcium atom and two fluorine atoms.
How many grams of f are in 165 caf2 grams of?
To find the grams of F in 165 g of CaF2, you need to consider the molar mass of CaF2. Calcium (Ca) has a molar mass of about 40.1 g/mol, and fluorine (F) has a molar mass of about 19 g/mol. So, the molar mass of CaF2 is about 40.1 + (19 x 2) = 78.1 g/mol. Then, you can calculate the grams of F in 165 g of CaF2 by determining the proportion of F in the compound CaF2 compared to its total molar mass.
Is CaF2 pseudo solid?
yes
What is the lattice constant of calcium fluoride?
The lattice constant of calcium fluoride (CaF2) is approximately 5.462 Å (angstroms).
