If it takes 436kJ to break a bond how many kilojoules are released when the same bond is formed?
When a bond is formed, the same amount of energy is released as what was required to break the bond, so 436 kJ would be released when the bond is formed. This is due to the principle of energy conservation in chemical reactions.
What must energy do to break achemical bonds for a reaction to occur?
Energy must be absorbed to break chemical bonds for a reaction to occur. This energy input is needed to overcome the bond's stability and allow new bonds to form in the reaction.
The process below is exothermic what must be true about the bond energies of the reactants and the products?
In an exothermic reaction, the total bond energy of the reactants is higher than that of the products. This means that the formation of new bonds in the products releases more energy than is required to break the bonds in the reactants. As a result, energy is released to the surroundings in the form of heat. Therefore, the bond energies of the products must be lower than those of the reactants.
If two atoms are bonded with a bond energy of 455 kJ what must be done to break the bondAsk us anything?
455 kJ of energy must be added (if it’s wrong I’m sorry)
When bonds are broken what type of energy is released?
There is a repulsion force between electrons of two atoms and nucleus of same atoms. But if attractive force between nucleus of one atom and electrons of other atom must be more than repulsion force to make a bond. The excess repulsion force is released as energy during bond formation.
What must be added to a system to break a bond?
Energy must be added to a system to break a bond.

When a bond is formed, the same amount of energy is released as what was required to break the bond, so 436 kJ would be released when the bond is formed. This is due to the principle of energy conservation in chemical reactions.
If two atoms are bonded with a bond energy of 212 kJ what must be done to break the bond?
To break the bond between two atoms with a bond energy of 212 kJ, you will need to supply at least 212 kJ of energy to overcome the bond's strength. This can be done through processes like heating or chemical reactions that provide the necessary energy to break the bond.
Why the bond energy of HF is greater than HBr?
Fluorine has the highest electronegativity of any element. Therefore, the energy released when hydrogen and fluorine react is greater than the energy released when hydrogen and bromine react, and that energy must be resupplied to cause either bond to break.

Energy must be absorbed to break chemical bonds for a reaction to occur. This energy input is needed to overcome the bond's stability and allow new bonds to form in the reaction.
What must be true about the bond energies the reactants and the products?
In a chemical reaction, the total bond energy of the products must be lower than the total bond energy of the reactants for the reaction to be exothermic (energy released) and vice versa for an endothermic reaction (energy absorbed). This is based on the principle of conservation of energy.

Why do bond enthalpies have positive values?
Bond enthalpies have positive values because they represent the energy required to break chemical bonds in a molecule, which is an endothermic process. When bonds are broken, energy must be absorbed to overcome the attractive forces between the atoms, resulting in a positive value. This positive value indicates that energy is needed to separate the atoms, reflecting the stability provided by the bond when it is intact.
Does breaking old bonds require energy and forming new bonds release energy?
In order to break a bond, you need to apply more energy than that holding it together. Energy is released when the bond is broken (the energy that was previously holding the bond together.
Explain why a triple bond between two nitrogen atoms is greater than a double bond between two oxygen atoms?
Electrons have a negative charge and the nuclei they surround have a positive charge. When the two particles approach one another the electron clouds can overlap. When this happens, under certain circumstances, the electrons that are between two nuclei can be attracted to both nuclei, holding them together. This force of attraction is known as a chemical bond. When the atoms form a bond they become lower in energy and the system is more stable. The energy saved by moving to a more stable situation is released as heat. For this reason bond formation is always exothermic, i.e. heat energy is released. Conversely, in order to break a chemical bond energy must be used - it is an endothermic process. Covalent bonding occurs between atoms of non-metals
