Ascientist is measuring the pressure that is exerted by each of the following gases in the atmosphere: carbon dioxide, oxygen, and nitrogen. which term most likely describes what she is measuring?

My guess would be partial pressure. The scientist is most likely measuring the partial pressure of the gases in the atmosphere. It is the pressure that would be exerted by one of the gases in a mixture if it occupied the same volume on its own. Hope this answers the question. 

Hno3(aq) → h+(aq) + no3−(aq). picture ii best represents the strong acid hno3. strong acids are strong electrolytes
