What is the definition of static enthalpy?
For a gas it is the value of u+pv where u=internal energy p=pressure v=volume
What is the definition of stipulative?
stipulative definition is stipulative definition

the two types of definition are the formal and informal definition.

Is the ionization enthalpy of the first two elements of isotopes same?
Ionization enthalpy of isotopes should be theoretically the same.But the recorded values aren't equal..nobody knows why..
What is the significance of isolated gaseous atom while defining the ionization enthalpy?
isolated gaseous atoms ionization enthalpy is taken as reference value and its required to compare this values to various ions of this elements and to compare this values with various elements
How would you explain the fact that the first ionization enthalpy of sodium is lower than that of magnesium but its second ionization enthalpy is higher than that of magnesium?
Sodium has only one valence electron, and when that is donated to some other atom, the remaining ion has a noble gas configuration that is highly stable. Disrupting that by another ionization requires much energy. Magnesium has two valence electrons; therefore the second is almost as easy to donate as the first. The third ionization enthalpy of magnesium would be very high.
The Literature value of enthalpy ionization of alanine?
The literature value for the enthalpy of ionization of alanine is approximately 170 kilojoules per mole. This value represents the energy required to remove an electron from a gaseous alanine molecule to form a positively charged ion. It is an important parameter in understanding the chemical properties and reactivity of alanine.
The ionization energy for sodium is 496 kJmol The electron affinity for chlorine is -349 kJmol what is the enthalpy?
The enthalpy change for forming sodium chloride from its elements can be calculated using the equation: Enthalpy change = Ionization energy of sodium + Electron affinity of chlorine. Plugging in the values, we get: 496 kJ/mol + (-349 kJ/mol) = 147 kJ/mol. Therefore, the enthalpy change for forming sodium chloride is 147 kJ/mol.
Which element has the highest ionization rate Sodium aluminum calcium or phosphorus?
phosphorous has highest ionization enthalpy because along the period ionization will increase.
Name the elements with highest ionisation enthalpy?
The elements with the highest ionization enthalpy are helium, neon, and argon. These noble gases have full valence electron shells and are very stable, making it difficult to remove an electron from them.
What element are most reactive on the table?
Sodium, Potassium, and other alkali metals are very reactive due to the low ionization enthalpy. Flourine, Chlorine and other halogens are very reactive due to the high negative electron gain enthalpy.
What elements on the table are most reactive why?
Sodium, Potassium, and other alkali metals are very reactive due to the low ionization enthalpy. Flourine, Chlorine and other halogens are very reactive due to the high negative electron gain enthalpy.
Why does oxygen gas not have an enthalpy of formation but ozone does?
Oxygen gas (O2) does not have an enthalpy of formation because it is an element in its standard state, which has an enthalpy of formation of zero by definition. Ozone (O3), on the other hand, is a compound and has a defined enthalpy of formation because it is formed from its elements in their standard states.
The amount of energy that is needed to remove the most loosley held electron is referred to as the what?
The amount of energy needed to remove the most loosely held electron is referred to as the ionization energy. It is the energy required to remove an electron from a gaseous atom or ion.
What is the best definition of the enthalpy of a reaction?
The enthalpy of a reaction is the heat change that occurs during a chemical reaction at constant pressure. It represents the difference in energy between the products and reactants in the reaction.
