Differences between science and pseudo science?
Pseudo means "false" so pseudoscience is something claiming to be science that isn't. And science is ability to produce solutions in some problem domain
Why is pseudo science not considered real science?
It is something that is not testable, whereas science is!
Is phrenology science or pseudo science?
Only an old pseudoscience (Gall, 1796).
Is rock solid liquid or gas?
1. Earth (the material) is a solid. 2. Earth (the planet) is a solid with a liquid center.
What state of matter is ice?
its a solid state.
What is pseudo solid in chemistry?
Pseudo solids are amorphous solids (as glass).
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)
What is the name for the ionic compound caf2?
CaF2 is calcium fluoride.
Is CaF2 a covalent compound?
The bonding in calcium fluoride (not "flouride") is ionic, not covalent.
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 formula for fluorite?
CaF2.
What element is CaF2?
Its is an Ionic compound
What is the name CaF2?
calcium flouride
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".
Is CaF2 a covalent or ionic bond?
ionic
Why is the chemical formula for fluorite?
Formula: CaF2
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.
