chemistry Sodium hydride (NaH) crystallizes in the rock-salt structure, with four formula units of NaH per cubic unit cell. A beam of monoenergetic neutrons, selected to have a velocity of 2.639×10^3 m s^-1, is scattered in second order through an angle of 2θ = 36.26° by the parallel faces of the unit cells of a sodium hydride crystal. (a) Calculate the wavelength of the neutrons. (b) Calculate the edge length of the cubic unit cell. (c) Calculate the distance from the center of an Na^+ ion to the center of a neighboring H^- ion. (d) If the radius of an Na^+ ion is 0.98 A°, what is the radius of an H^- ion, assum ing the two ions are in contact? Verified answer

Which of these is a neutral salt Na2SO4?Sodium sulphate (Na2SO4) is formed by a reaction between sodium hydroxide and sulphuric acid which are strong base and acid, respectively. Thus, it is a neutral salt with a pH of 7.
What are examples of neutral salts?Neutral Salt: They are formed by the neutralisation of strong acids and strong bases, are called neutral salts because their aqueous solutions are neutral to litmus. Examples: The compounds like NaCl, KCl, K2S04, NaN03, KCl03, KClO4 etc are neutral salts.
Which of these is a neutral salt Na2SO4 Brainly?Answer. Answer: Sodium Sulphate (Na2SO4) and Potassium Chloride (KCL) are neutral salt. Acidic salts are formed when strong acids and weak bases react chemically.
