Meet the Metal That Defines the Second and Has a Tendency to Burst Into Flames

SOLVED: Predict the chemical formula for cesium fluoride, given the formula of sodium chloride, NaCl.

SOLVED: The lattice energy of cesium fluoride is the energy required for the following reaction: CsF(s) → 3 Cs (g) F-(g) ΔHrxn ΔHlattice. Use the Born-Haber cycle to calculate ΔHlattice for CsF(s) from the information given below: kJ/molEquation 1: 2 Cs(s) F2(g) → 2 CsF(s) ΔH1 = -1106 kJ/molEquation 2: Cs(s) → Cs(g) ΔH2 = 77 kJ/molEquation 3: F2(g) → 2 F(g) ΔH3 = 159 kJ/molEquation 4: Cs(g) → Cs (g) e- ΔH4 = 376 kJ/molEquation 5: F(g) e- → F-(g) ΔH5 = -327 kJ/mol

One of the few xenon compounds that form is cesium xenon heptafluoride (CsXeF 7 ) . How many moles of CsXeF 7 can be produced from the reaction of 12.5 mol of cesium fluoride with 10.0 mol of xenon hexafluoride? CsF(s) XeF6(s) →Cs XeF7(s) | Numerade

In cesium atomic clock is used... | Filo

The stability of the cesium clock used as an atomic time standard is such that two cesium clocks would gain or lose 1  s with respect to each other in about 300,000 y. If this same precision were applied to the distance between New York and San Francisco ( 2572 mi ), by how much would successive measurements of this distance tend to differ? | Numerade
