The specific heat of aluminum is 0.897 j/g•°c. which equation would you use to calculate the amount of heat needed to raise the temperature of 0.75 g of aluminum from 7°c to 29°c?
a. q = 0.75 g x 0.385 j/g•°c x 29°c
b. q = 0.75 g x 0.385 j/g•°c x 22°c
c. q = 0.75 g x 0.897 j/g•°c x 22°c
d. q = 0.75 g x 0.897 j/g•°c x 29°c

Which of your 24 wells had indications that a chemical reaction occurred? how were you able to tell that a chemical reaction occurred? which of your 24 wells had indications that a physical reaction occurred? how were you able to tell that a physical reaction occurred? report on both mixing and evaporation. make a general statement about whether your hypotheses were validated or rejected. must your hypotheses be correct for this to be a successful laboratory?
