A calorimeter holds 125 g water at 31.0°C. A sample of hot copper is added to the water. The final temperature of the water and copper is 39.0°C. What is the change in enthalpy
associated with the change in the water's temperature? The specific heat capacity of
water is 4.19 J/gºC. Which substance had a positive q value?

List four observations that indicate that a chemical reaction may be taking place

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed
