Consider the hall reactions below for a chemical reaction
znzn2+ (aq) + 2e
cu? " (aq) + 2e" - cu(s)
what is the overall equation for this chemical reaction?
zn(s) + cu2+ (aq) -- zn2+ (aq) + cu(s)
zn(s) + cu2+ (aq) cu* (ag)+ 2e"
zn2+ (aq) + cu(s) cu(aq) + zn(s)
zn2+ (aq) + 2e" - cu2(aq) + 2e

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.      

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
