The attractive force between two ions in Na20, Fc is 8.64x10-9N. What is the bond length a0 (in nm) given that valence of the charged Na+ is Z1=+1, for O-, is Z2 =-2, the charge of a single electron q is 0.16x10-18 C and the proportionality constant k0=9x109 V.m/C? Note that K=k0(Z1q)(Z2q) and that 1 V.C = 1 J.

What are the names for the followinng compounds?
A gaseous binary compound has a vapor density that is 1.94 times that of oxygen at the same temperature and pressure. When 1.39 g of the gas is burned in an excess of oxygen, 1.21 g water is formed, removing all the hydrogen originally present.(a) Estimate the molecular mass of the gaseous compound.(b) How many hydrogen atoms are there in a molecule ofthe compound?(c) What is the maximum possible value of the atomicmass of the second element in the compound?(d) Are other values possible for the atomic mass of thesecond element? Use a table of atomic masses to identify the element that best fits the data.(e) What is the molecular formula of the compound?
Explain properly all the questios
please help with parts e,h,i with explanation as to hoe they are named
please ASAP. Thank you. Assuming the atomic radii are as follows: Ca++ > Mg++ > Be++ And the electronegativities are as follows: Be++ > Mg++> Ca++ Which ion would is unlikely to pass through a small pore? Be++ Mg++ Ca++ All of them
(a) The ionization energy of potassium (K) is 4.34 eV and the electron affinity of chlorine (Cl) is -3.61 eV. The Madelung constant for the KCl structure is 1.748 and the distance between ions of opposite sign is 0.314 nm. On the basis of these data only, compute the cohesive energy of KCl per ion pair. (b) The observed cohesive energy of KCl is 6.42 eV per ion pair. On theassumption that the difference between this figure and that obtained in (a) is due to the exclusion principle repulsion, find the exponent n in the formula Br^-n for the potential energy arising from this source.
