A 15.2-g sample of NH4NO3 dissolves in 82.5-g of water in a calorimeter, and the
temperature drops from 25.8˚C to 11.7˚C.
Find ∆H for the process.
NH4NO3 (s)→ NH4

(aq) H = ?

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.
