Which half- reaction equation represents reduction?
1) Cu --> Cu^2+ + 2e^-
2) Cu^2+ + 2e^- --> Cu
3) Ag + e^- --> Ag^+
4) Ag^+ --> Ag + e^-

Define dew point. i am writing this part to be able to ask the question

Draw the skeletal structures of two different molecules that are each made of 5 carbon atoms and 12 hydrogen atoms.

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
