What is the enthalpy of HDPE?
The enthalpy of high-density polyethylene (HDPE) can vary depending on its specific form and conditions. However, HDPE typically has a heat of fusion enthalpy of around 110 J/g.
Do transitional metals have high density?
Transition metals can have high density due to their high atomic masses and compact atomic structures. However, the density of transition metals can vary widely depending on the specific metal and its crystal structure.
How does molar enthalpy of fussion of ice compare with the molar enthalpy of fussion of other solids?
The molar enthalpy of fusion of ice is relatively high compared to the molar enthalpy of fusion of many other solids. This is because ice requires a significant amount of energy to change from a solid to a liquid state due to its strong hydrogen bonds. However, there are some solids, such as metals, that have higher molar enthalpies of fusion than ice.
Which elements have positive electron gain enthalpy?
It should be Fluorine but Chlorine has most EGE value because the F atom has very small sizeas compared to Cl. Addition of extra electron creates higher electron density and thus strong electron - electron repulsion comes into act. So extra electron is not accepted with the same ease as in the case of remaining elements of the group
What is the relationship between metallic bond strength and enthalpy of vaporization?
Metallic bond strength refers to the amount of energy as heat required to vaporize the metal. The enthalpy of vaporization is defined as the amount of energy absorbed as heat when a specified amount of substance vaporizes at constant pressure. Metallic bond strength increases as the enthalpy increases.
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.
How can you tell what kind of bonds an elements atoms have?
atoms having low Ionisation enthalpy and ones having high electronegativity form ionic bond
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.
Does chemical adsorption have a high adsorption enthalpy?
no
What is the enthalpy of HDPE?
The enthalpy of high-density polyethylene (HDPE) can vary depending on its specific form and conditions. However, HDPE typically has a heat of fusion enthalpy of around 110 J/g.
What is a good sentence using the word enthalpy?
The first is the comparatively very high lattice enthalpy of the solid fluoride.
Why HF has high neutralization enthalpy?
Because of high value of hydration energy.
What has the author H Groenig written?
H. Groenig has written: 'High enthalpy testing in hypersonic shock tunnels' -- subject(s): Hypersonic shock tubes, High enthalpy testing
What is the significance of high hydration enthalpy?
Enthalpy of hydration is the energy change for converting 1 mol of an anhydrous substance to 1 mol of the hydrated substance. More the hydration enthalpy more will be the energy released on getting hydrated. The stability of any species is inversely proportional to the energy content and any chemical species tends to becoming more and more stable. Thus having high hydration enthalpy means it will become more stable on hydration and thus it will tend to forming its hydrate.
What is the enthalpy of combustion of these compounds?
The enthalpy of combustion of a compound is the amount of energy released when one mole of the compound is burned in oxygen, typically measured in kilojoules per mole (kJ/mol). It varies significantly among different compounds based on their chemical structure and the type of bonds present. For example, hydrocarbons generally have high enthalpy of combustion values due to the high-energy carbon-hydrogen bonds. Specific values for compounds can be found in thermodynamic tables or calculated using standard enthalpy of formation data.
Do transitional metals have high density?
Transition metals can have high density due to their high atomic masses and compact atomic structures. However, the density of transition metals can vary widely depending on the specific metal and its crystal structure.
What is electron gen enthalpy?
Electron Gain Enthalpy is the amount of Energy released when an isolated gaseous atom accepts an electron to become a monovalent gaseous anion.For Example:Atom(gas) +Electron ---->Anion(gas) +Energy(Electron Gain Enthalpy)
