What is the difference between delta H and delta E in a chemical reaction?

Delta H represents the change in enthalpy, which is the heat energy exchanged during a chemical reaction. Delta E represents the change in internal energy, which includes both the heat energy and work done in a reaction. In simpler terms, delta H focuses on heat transfer, while delta E considers both heat and work.


What is the Delta E chemistry formula used to calculate the change in energy of a chemical reaction?

The Delta E formula in chemistry is used to calculate the change in energy of a chemical reaction. It is represented as E E(final state) - E(initial state), where E is the change in energy, E(final state) is the energy of the system in its final state, and E(initial state) is the energy of the system in its initial state.


What is the value of e for this process?

The value of e for this process is approximately 2.71828.


What is the difference between delta H and delta E in thermodynamics?

In thermodynamics, delta H represents the change in enthalpy, which is the heat energy exchanged during a process at constant pressure. Delta E, on the other hand, represents the change in internal energy, which is the total energy of a system. Enthalpy includes both internal energy and the energy required to change the system's volume, while internal energy only considers the system's total energy.

What is the formula for delta E?

The formula for delta E is ΔE = E_final - E_initial, where ΔE represents the change in energy, E_final is the final energy state, and E_initial is the initial energy state.


Calculate delta E for the system in which a gas absorbs 31 J of heat and does 18 J of work on the surroundings?

The change in internal energy (( \Delta E )) of the system can be calculated using the First Law of Thermodynamics, which states that ( \Delta E = Q - W ), where Q is heat added to the system and W is the work done by the system. Given that the gas absorbs 31 J of heat (( Q = 31 J )) and does 18 J of work on the surroundings (( W = -18 J ) since work done by the system is negative), the change in internal energy would be ( \Delta E = 31 J - (-18 J) = 49 J ). Therefore, ( \Delta E = 49 J ) for the system.
