The relationship between qrxn (heat of reaction) and qsur (heat of surrounding) is described by the first law of thermodynamics, which states that the heat released or absorbed by a reaction is equal and opposite to the heat gained or lost by the surrounding environment. In an exothermic reaction, qrxn is negative and qsur is positive as heat is released to the surroundings. In an endothermic reaction, qrxn is positive and qsur is negative as heat is absorbed from the surroundings.

Gay lussac's law relates temperature of a gas to its?
Gay-Lussac's law relates the pressure of a gas to its temperature, under constant volume and amount of gas. It states that the pressure of a gas is directly proportional to its temperature in kelvin.
What value is needed to convert mass to volume in stoichiometry problem?
The density of the substance is needed to convert mass to volume in a stoichiometry problem. Density is a measure of how much mass is contained in a given volume. It relates the mass of a substance to its volume.
What is difference between the difference between brittleness and hardness?
Hardness measures a material's ability to resist permanent deformation, whereas brittleness measures a material's tendency to fail or break without undergoing significant deformation. In other words, hardness relates to the resistance to scratching or indentation, while brittleness relates to the tendency to fracture.
What bible verse relates to the dissolving of salt in hot and cold water?
There is no specific Bible verse that mentions the dissolving of salt in hot and cold water. The Bible does mention salt in various contexts, such as being the salt of the earth (Matthew 5:13) and using salt as a metaphor for seasoning or flavoring in cooking.
Is density a colligative property?
No, density is not a colligative property. Colligative properties depend on the number of solute particles in a solution, whereas density is a physical property that relates to the mass of a substance per unit volume.
What is qrxn the symbol for?
"qrxn" typically represents the heat transferred during a chemical reaction.
How do you determine the change in temperature and final temperature of an endothermic reaction?
The amount of heat generated or absorbed in a chemical reaction can be studied using a calorimeter. our chemical reaction) is placed in a well-insulated vessel surrounded by water (surroundings). A thermometer is used to measure the heat transferred to or from the system to the surroundings. The heat that the chemical reaction puts out, or takes up, (qrxn) is simply the moles of the limiting reagent, nlimiting reagent times ΔHrxn. qrxn = nlimiting reagent·ΔH
