WebCommunity Experts online right now. Ask for FREE. ... Ask Your Question Fast! WebThe specific heat of water is approximately 4.184 J/g °C, so we use that for the specific heat of the solution. Substituting these values gives: q solution = ( 4.184 J/g °C) ( 1.0 × 10 2 g) ( 28.9 °C − 22.0 °C) = 2.9 × 10 3 J Finally, since we are trying to find the heat of the reaction, we have: q reaction = − q solution = −2.9 × 10 3 J
