In a constant‑pressure calorimeter, 70.0 ml of 0.350 m ba(oh)2 was added to 70.0 ml of 0.700 m hcl. the reaction caused the temperature of the solution to rise from 22.32 ∘c to 27.09 ∘c. if the solution has the same density and specific heat as water ( 1.00 g/ml and 4.184j/g⋅k,) respectively), what is δ for this reaction (per mole h2o produced)? assume that the total volume is the sum of the individual volumes.

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.
