Run 2 B, all questions, please help me, thank you very much
A chemical reaction involves breaking, making, or changing chemical bonds. These alterations in bonding lead to a change in enthalpy, AHo, between the products and reactants. This enthalpy change takes into account the change in intermal energy in the system and the work done by the system on its surroundings during the reaction. If the reaction occurs at a...

Calorimetry is a method used to measure enthalpy, or heat, changes that occur during chemical processes. Two common calorimeters are constant-pressure calorimeters and constant-volume (or "bomb") calorimeters. A simple constant-pressure calorimeter can be made from a foam coffee cup and a thermometer; energy changes in a reaction are observed via a temperature change of the solution in the cup. Bomb calorimeters are used to measure combustion and other gas-producing reactions, where the reaction is observed in a strong, sealed vessel....

1.) A thermometer placed in a solution undergoing a chemical reaction indicates an increase in temperature as the reaction proceeds. Is this reaction endothermic or exothermic? Describe if heat energy is lost or gained from the reaction (the system) to the surroundings. What is the sign of the enthalpy change (H) of this reaction?

Name Experiment 5- Post-lab Questions 1. In Reaction B, you observed magnesium metal reacting with a hydrochloric acid solution to produce hydrogen gas and a magnesium chloride solution. Another reaction that has a gaseous product is the reaction of a hydrochloric acid solution (HCl(ag)) with sodium sulfite (Na,so,(ag)) solution to produce a sodium chloride solution (NaCl(aq)) and gaseous sulfur dioxide (S0,(g)). Write a balanced chemical equation for this reaction. 2. The sulfur dioxide produced by aqueous chemistry in the previous...

Be sure to use expanded structural formulas for all chemical species. Include all bonds, non-bonding electrons, formal charges, and electron-flow arrows. DO NOT use bond-line formulas, but rather explicitly show atomic symbols. For this mechanism, show the individual resonance contributors for the arenium...
