What type of change must occur to form a compound?
If this is for SOS the answer is chemical.The following answer is incorrect."a change in energy has taken place. when a new compounds is fromed it produces either heat energy, light energy or both."
How does thermal energy cause substances to undergo chemical change how does thermal energy cause substances to undergo chemical change?
Thermal energy cause thermal decomposition of a compound; the bonds between atoms are weakened.
Is sugar water a compound or mixture or element?
It is both. A compound mixture is made of pure elements. For instance; salt is made of sodium chloride. Sodium voilently reacts with water, and chloride is extremely toxic, but when you eat salt, nothing happens. Why? A chemical change undergoes. A compound is 2 or more elements chemically mixed.
Determining lattice energy from Born-Haber cycle data requires the use of?
various thermodynamic data including enthalpies of formation, ionization energies, electron affinities, and dissociation energies. These data are used to calculate the overall energy change associated with the formation of an ionic compound from its elements. The lattice energy is the energy required to separate ions in a solid crystal structure into infinitely separated gaseous ions.
Fireworks give off what energy?
Firecrackers represent energy change as well as the preservation of force. To extend the explosives up requires transformation of compound energy to motor energy. The active energy is utilized to conquer gravity and is changed over completely to possible energy all the while.

Is energy given out when elements are formed from a compound?
In almost all cases, it requires energy to break a compound down to its constituent elements. There are, however, some cases in which the decay of a compound into its constituent elements would release energy. Platinum hexafluoride would be an example.
The change in enthalpy that accompanies the formation of a compound from its elements?
The energy change that happens when a substance forms from its elements (APEX)
Is energy a compound?
No, energy is not a compound. Energy is a property that can be found in various forms such as kinetic, potential, thermal, or electromagnetic energy. It is not made up of different elements like compounds are.
What is the best definition of the enthalpy of formation Hf?
The enthalpy of formation (ΔHf) is the heat associated with the formation of one mole of a compound from its elements in their standard states. It represents the energy change when the compound is formed from its constituent elements under standard conditions.
How can the elements in an atom can have potential energy?
The chemical bonds between the atoms of the elements in a molecule or ionic compound contain potential energy.
What event must take place to separate a compound into separate elements?
A chemical reaction must occur to separate a compound into its separate elements. This may involve breaking the bonds holding the elements together within the compound, typically through the addition of energy or the introduction of another reactant.
Two or more elements that combine as a result of a chemical reaction form?
A compound is formed. The process may require a certain amount of energy (heat) to react, or it may release energy in the form of heat.
How can one determine the lattice energy of a compound?
The lattice energy of a compound can be determined by calculating the energy required to separate the ions in the compound to an infinite distance apart. This can be done using the Born-Haber cycle, which involves considering the formation of the compound from its elements and the energy changes involved in the process. The lattice energy is a measure of the strength of the ionic bonds in the compound.
Why did each compound produce a flame of a different color?
Different elements have different emission spectra, meaning that if the electrons in an atom are excited, they will release that energy in different color of light. The flame color depends on the elements in the compound.
Is it true of false that the energy of an ionic compound is higher than that of the separate elements that formed it?
I believe that it depends on the elements that you are combining or seperating.
What is an important energy-storing compound that contains only the elements carbon hydrogen and oxygen?
Carbohydrates :)
