The addition of hydrochloric acid to a silver nitrate solution precipitates silver chloride according to the reaction: agno3(aq) + hcl(aq) → agcl(s) + hno3(aq) when you combine 50.0 ml of 0.100 m agno3 with 50.0 ml of 0.100 m hcl in a coffee-cup calorimeter, the temperature changes from 23.40 °c to 24.21 °c. calculate δhrxn for the reaction as written. use 1.00 g/ml as the density of the solution and c = 4.18 j/g ∙ °c as the specific heat capacity.

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
