Jennifer was conducting the experiment testing the question: "What is the effect of different colors oflight on plant height?" In her experiment she was going to test red, yellow, green and blue light for sixdays. She measured the plants after each day. a. What is the Independent Variable. [1]b. What is the dependent Variable[1]

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
