using c=λν and e=hν (where h or planck’s constant is 6.626 *10 ^-34js). find the energy that a wavelength has if it has a wavelength of 3.000*10^7 nm. show your work

E=hc/λ =6.626×10^-34×3 ×10^8 / 3×10^7 × 10^-9 = 6.626×10 ^-24J.

This is not a full question, text me and i'll you

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
