For the line spectra experiment you analyzed the balmer series to determine ni and nf in the rydberg equation. the balmer series occurs in the visible region of the electromagnetic spectrum. another set of spectral lines occurs outside of the visible region. these lines occur at 1875 nm, 1282 nm, 1094 nm, and 1005 nm. nf for this series is 3. what is ni for the spectral line at 1094 nm? hint: it is an integer less than 10.

If 10.g of agno3 is available, what volume of 0.25 m agno3 can be prepared

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
