An electron in a hydrogen atom is excited with electrical energy to an excited state with n = 2. The atom then emits a photon. What is the value of n for the electron following the emission?
Solution Given that X forms two compounds namely XO and XCl .We have been2sked to fin4X. Step 1 (a)The reaction of XCl with wa4 can be written as given below XCl 4(l) 02X(l) +4H2 (s) (aq) Thus the product other than XO formed in the reaction is HCl 2
