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.


How many moles of Ca are there in 0.18moles of Ca F2?

There are 0.18 moles of Ca2+ ions in 0.18 moles of CaF2.


What is the coefficient for F2 in Ca plus F2 CaF2?

The coefficient for F2 in the chemical equation Ca + F2 → CaF2 is 1.


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 compound does Ca and F make?

Calcium fluoride, CaF2


How many miles from Stockton Ca to Brisbane Ca?

90 miles or 145 kilometers


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 oxidation number of calcium (Ca) in CaF2?

The oxidation number of calcium (Ca) in CaF2 is +2. This is because fluorine (F) typically has an oxidation number of -1, and the overall charge of CaF2 is neutral. Since there are two fluorine atoms each with a -1 charge, the calcium atom must have a +2 oxidation number to balance the charges.


What is the name of the compound ionic bond of calcium and fluorine?

CaF2, Calcium Fluoride. It is useful in iron smelting


How many grams of nitrogen are there in 7.5g of Ca NO3 2?

Explain what the formula CaF2 tells you about this compound?

Ca+2 F-1 <----- these are the ions and their charges Ca+2 F-1 F-1 <----- the charges have to add up to zero, so two -1 fluorine ions cancel out one +2 calcium ions CaF2 <---- simplify
