Consider the heating curve.
A graph of temperature versus time, with time in minutes as the horizontal axis and temperature in degrees Celsius as the vertical axis. 5 sections of line are labeled: 1 from 0 minutes, negative 50 degrees to 1, 0 degrees. 2: from 1, 0 to 5, 0. 3: from 5, 0 to 9, 2200. 4: from 9, 2200 to 17, 2200. 5: from 17.0, 2200 to off the chart at 2,400 degrees.

Count the number of each type of atom in the equation below, and then balance the equation. write in the numbers of atoms and coefficients. add a 1 if there should be no coefficient. cs2(l) + o2(g) → co2(g) + so2(g) c [ ] s [ ] o > c [ ] s [ ] o [ ] cs2(l) + [ ] o2(g) > [ ] co2(g) + [ ] so2(g)

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
