6. GENERALIZATION Direction: MODIFIED TRUE or FALSE: Write the word TRUE if the statement is correct and if not, underline the word or statement that sentence incorrect and write the correct answer on your answer sheet. Write your answer on a separate sheet of paper. swer 1. The law of conservation of energy states that energy can either be created or destroyed. 2. A closed system is a system that has external interactions, such as energy transfers into or out of the system boundary. 3. According to the first law of thermodynamics, when heat enters or leaves a system, the system gains or loses an amount of energy equal to the amount of heat transferred. 4. A measure of energy transfer that occurs when an object is moved over a distance by an external force is known as heat. 5. The transformation of chemical energy into kinetic and heat energy by a car engine is a manifestation of the first law of thermodynamics. 6. An open system could not create or destroy energy. 7. Energy is a…

O Endothermic, because in an endothermic reaction, energy is absorbed. O Exothermic, because in an exothermic reaction, energy is released. O Exothermic, because in an exothermic reaction, energy is absorbed. O Endothermic, because in an endothermic reaction, energy is released.

I Review | Constants | Periodic Table 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") Part A 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. The idea behind calorimeters is that if they are sufficiently insulated from the outside environment, any energy gained or lost in the chemical reaction will be directly observable as a temperature and/or pressure change in the calorimeter. A total of 2.00 mol of a compound is allowed to react with water in a foam coffee cup and the reaction produces 174 g of solution. The reaction caused the temperature of…

Please help me with this  Check if my responses below are correct for the pre lab question on determining ethalpy for neutralization reaction's When using the same graduated cylinder to measure the volumes of HCl(aq) and NaOH(aq) it is important to rinse the cylinder with water and a small amount of the second reactant before measuring the volume of the second reactant because any residue of the first reactant could react with the second reactant, leading to incorrect measurements and potentially affecting the accuracy of the experiment.   2. Letting the solutions of HCl(aq) and NaOH(aq) sit overnight allows any excess heat generated during the reaction to dissipate, resulting in a more accurate measurement of the enthalpy change of the reaction. It also allows for any undissolved solids to settle out, ensuring that only the dissolved reactants are used in the experiment. 3. If acid comes in contact with your skin, it is important to flush the area with plenty of cold water rather…

Hi! This is a lab task. Given the table of data, please help me answer the missing four values on the last table. Thanks! This would mean a lot!

I need help with part a. The second picture is data.

Please answer both the parts otherwise I'll downvote.
