Energy must be _______ to break chemical bonds and _______ when chemical bonds form. Select the correct answer below: added, released released, added added, added released, released
Homework Answers
Energy must be added to break chemical bonds and released when chemical bond form.
we need energy to break bonds as we have to take two atoms away from each other which are connected through atraction forces so we need energy. similarly energy is released when bonds are formed as atoms come togather because of attraction force o they release their potential energy.

the enthalpy change in a chemical reaction can be determined using bond energies. energy must be added or absorbed to break bonds and that energy is released when bonds are formed. therefore ,you can calculate the total enthalpy of the reaction using following formula: dH= bonds broken-bonds formed Using bond energies, calculate the change in energy that accompanies the following reaction: H2 + O2 -> 2H2O Bond Bond Energy H-H 432 kJ/mol O-O 498 kJ/mol H-O 467 kJ/mol

Question 5 1 pts Which of the following is true of an exothermic reaction? Strong bonds break and weak bonds form: this means that more energy is released than absorbed Weak bonds break and strong bonds form: this means that more energy is released than absorbed The bonds that break and those that form are of approximately the same strength. Strong bonds break and weak bonds form: this means that more energy is absorbed than released Weak bonds break and...

These UV photons can break chemical bonds in your skin to cause sunburn—a form of radiation damage. If the 320 nm radiation provides exactly the energy to break an average chemical bond in the skin, estimate the average energy of these bonds in kj/mol. Please provide a detail step of your methods. Thank you so very much!!!

ENERGY FROM CHEMICAL REACTIONS (page 8) Many chemical reactions release energy, while others require energy to happen. These energy changes that occur during chemical reactions are due to changes in bonding between the reactant molecules and product molecules. Breaking bonds between atoms always requires energy, while creating bonds between atoms always releases energy. Analyze each of the two chemical reactions below by calculating the total amount of energy needed to break the bonds in the reactants, the total amount of...
