Writing the net ionic equation
vazorg [7]

First write the molecular equation with states:


(NH4)2S (aq) + 2AgNO3(aq) → Ag2S (s) + 2NH4NO3


Now write a full ionic equation by separating into ions all substances that dissociate: anything (s) (g) or (l) does not dissociate


2NH4 + (aq) + S 2-(aq) + 2Ag+ (aq) + 2NO3- (aq) → Ag2S(s) + 2NH4 + (aq) + 2NO3- (aq)


To write the NET IONIC equation, inspect the full ionic equation above and delete anything that appears on both sides of the → sign:


Net ionic equation:

S 2-(aq) + 2Ag + (aq) → Ag2S(s)

Element c has a strong emmission aound 450nm Does this emmission line reprosent a lower of higher emergy line at 627 nm?
Julli [10]

It  respresents the higher energy level than 627nm .

<h3>What is a emission line ? </h3>

Emission lines are the glowing hot gas emits lines of light whereas absorption line  refers to the tendency of  cool atmospheric gas to absorb the same line of light.Some lights produce dark band when the light passes through gas in the atmosphere . There are two line spectrum  and absorption.

 spectrum is an excitement of  electrons from lower to higher energy levels and when it comes back it releases energy in the terms of colourful lights .

It represents the  higher energy levels than 627nm because Energy is inversly proportional to wavelength .
