The student takes 500.0ml of 2.00m HCl and 500.0 ml of 2.00 m KOH them in a calorimeter, they observe that the temperature rises from 23.2c to 34.1c . What is the change in energy that the student has observed in this trial?

1. if you have a gas at 127 degrees c, what is it's absolute temperature (kelvin)? a. 200kb. 300kc. 400kd. 500k2. if you had a gas whose absolute temperature measured 45 k, what is that temperature in celsius? a. -228 cb. -300 cc. 125 cd. 112 c

Can someone me with 3 and 4 plz. this is for masteries test.

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?
