In a constant-pressure calorimeter, 65.0 ml of 0.330 m ba(oh)2 was added to 65.0 ml of 0.660 m hcl. the reaction caused the temperature of the solution to rise from 23.60 °c to 28.10 °c. if the solution has the same density and specific heat as water (1.00 g/ml and 4.184 j/g·°c, respectively), what is δh for this reaction (per mole of h2o produced)? assume that the total volume is the sum of the individual volumes.

Adozen is 1221/12 = 1.751.75 x 12 = 21therefore, 1.75 is the answer.

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:

Using dilution equationm1v1 =m2v2 ; where m1 and m1 are the intiial and final concentration, and v1 and v2 are the initial and final volume.5  × 5 m = 8 l  × m2m2 = 25/8 = 3.125 mtherefore; the resulting molarity is 3.125 m
