What could make G become negative at a given enthaply and entropy?
Changing the temperature. my only explanation is I got it right so I hope this helps.
What is a description of the enthaply of a reaction?
The enthalpy of a reaction, often represented as ΔH, is the measure of the heat change associated with a chemical reaction at constant pressure. It indicates whether a reaction is exothermic (releasing heat, ΔH < 0) or endothermic (absorbing heat, ΔH > 0). The enthalpy change reflects the difference in enthalpy between the products and reactants, providing insight into the energy dynamics of the reaction. It is a crucial concept in thermodynamics and helps predict reaction behavior and stability.
How is Hess's law used to measure enthaply of a desired reaction?
Hess's law states that the total enthalpy change for a chemical reaction is the sum of the enthalpy changes for individual steps, regardless of the pathway taken. To measure the enthalpy of a desired reaction, one can combine known enthalpy changes from related reactions, manipulating them as necessary (e.g., reversing reactions or adjusting coefficients) to match the desired reaction. By applying Hess's law, the overall enthalpy change for the target reaction can be calculated using the enthalpy values of these referenced reactions. This approach is particularly useful when direct measurement of the enthalpy change is challenging or impossible.

How do you calculate wet bulb temperature?
Wet bulb temperature can be calculated using a psychrometric chart or formula that takes into account the dry bulb temperature and relative humidity of the air. It represents the lowest temperature that can be achieved through the process of evaporative cooling. Alternatively, there are online calculators and apps that can provide the wet bulb temperature based on the input parameters.
What does the enthaply of reaction measure?
The enthalpy of reaction measures the amount of heat absorbed or released during a chemical reaction at constant pressure. It indicates whether a reaction is exothermic (heat is released) or endothermic (heat is absorbed).
When a balloon is blown up then it is let go air molecules rush out of the balloon and join the air molecules in the earth's atmosphere. What happens to the enthaply in the balloon?
When the air rushes out of the balloon, it releases heat energy, which results in a decrease in enthalpy within the balloon. This process is known as an exothermic reaction, where energy is released to the surroundings.
What is the enthalpy of reaction-?
the heat released or absorbed in a reaction
Why does the oxidation number of all metals on the periodic table have a positive charge?
Metals tend to lose electrons to achieve a stable octet configuration. This loss of electrons results in a positive oxidation state. The positive charge corresponds to the number of electrons that the metal has lost in order to become stable.

What best describe the enthalpy of formation of a substance?
The enthalpy of formation of a substance is the energy change when a substance is formed from its elements in their standard states. It represents the heat energy released or absorbed during the formation process. A negative value indicates that the reaction is exothermic, while a positive value indicates an endothermic reaction.
