Given the two half-cell reactions for copper and iron below

standard

electrode potential (v)

cu →cu+2 +2e- -0.41

fe→ fe2+ 2e- 0.34

would you use a water pipe that consists of the two metals? justify your answer!

How many moles of no2 will form when 3.3 moles of cu are reacted with excess hno3?

What is the enthalpy of combustion (per mole) of c4h10 (g)? –2,657.5 kj/mol –5315.0 kj/mol –509.7 kj/mol –254.8 kj/mol

Some molecular compounds, such as hcl, ionize completely in solution. for molecular compounds such as h2co3, most molecules do not ionize in solution. which describes the properties of these two solutes? a. hcl and h2co3 have the same effect on the properties of the solution. b. hcl raises the freezing point of water more than h2co3 does. c. hcl raises the boiling point of water more than h2co3 does.
