Is hydrogen gas explosion endothermic or exothermic and why?
The explosion of hydrogen gas is exothermic because it releases energy in the form of heat and light. During the explosion, the chemical bonds in hydrogen gas are broken and new bonds are formed with oxygen, releasing more energy than is required to break the initial bonds.
When adding electric energy to water molecules can it cause the bonds between Hydrogen and oxygen to break?
Yes, adding electric energy to water molecules can cause the bonds between hydrogen and oxygen to break through a process called electrolysis. In electrolysis, an electric current is passed through water, which results in the splitting of water molecules into hydrogen and oxygen gas. This occurs when the energy supplied is sufficient to overcome the bond energy of the H-O bonds in water.
What types of bonds will break when frozen water is heated and becomes liquid?
Of course. The reason for water's solid structure when frozen is due only to hydrogen bonds, which form a type of crystal lattice structure. When heat is applied, these bonds break, and water becomes liquid once again. then you crap yourself.
Is energy released or required for evaporation to take place?
Energy is required for evaporation to take place. This energy, in the form of heat, is needed to break the bonds between liquid molecules so they can escape into the air as gas.
Do all chemical bonds hold potential energy?
No. some bonds actually require sustained energy to break apart (such as water). This is displayed in the use of a Hoffman apparatus, which requires an electrical current to split water into Hydrogen and Oxygen.
What happens when chemical bonds break and bonds form?
It takes energy to break a bond. then the atoms rearrange and can form new bonds releasing energy.
What happens to chemical bonds during energy exchanges?
During energy exchanges, chemical bonds can break or form. When bonds break, energy is absorbed, while when bonds form, energy is released. This process is essential for chemical reactions to occur and for energy transfer in biological systems.
How are temperature and hydrogen bonds related?
Hydrogen bonds are weaker bonds that form between hydrogen atoms and electronegative atoms like oxygen or nitrogen. Temperature affects the strength of hydrogen bonds because it influences the movement of molecules. At higher temperatures, molecules have more kinetic energy and move faster, which can break hydrogen bonds.
Waters high specific heat is mainly a consequence of the?
absorbtion and release of heat when hydrogen bonds break and form
Do hydrogen bonds have to break in order for water to increase in temperature?
a hydrogen bond is a weak interaction involving a hydrogen atom and fluorine, oxygen, or nitrogen atom...... there for it must form, not break because it is a weak interaction!
When water evaporates do the covalent bonds between O atoms and H atoms break or do the hydrogen bonds break and why?
When water evaporates, it is the hydrogen bonds between water molecules that break, not the covalent bonds within each water molecule. The hydrogen bonds are weaker intermolecular forces that hold water molecules together. Breaking these bonds allows the water molecules to escape as vapor.

What happens to the energy during a phase change?
When energy is added during a phase change the energy is used to break molecular bonds.
What happens to the energy added during the phase change?
When energy is added during a phase change the energy is used to break molecular bonds.
Why does hydrogen burns?
Hydrogen burns because the energy released from the H-O bonds it forms with water is greater than the energy required to break the H-H and O=O bonds in molecular oxygen and hydrogen. 2 H2 + O2 ---> 2 H2O
What happens to atoms during chemical changes?
Chemical changes involve breaking and forming of bonds between atoms. Chemical energy is required to break bonds. The formation of new bonds releases energy.
