If two atoms from the same element share three pairs of electrons in forming a molecule the bond is called a If two atoms from the same element share three pairs of electrons in forming a molecule the bond is called a coordinate covalent bond. single covalent bond. double covalent bond. triple covalent bond.

The required option is "a triple covalent bond."

Explanation:

Coordinate bonds are formed by sharing of electrons by only one of the atoms participating in the bond formation.Coordinate covalent bonds are formed in the molecules like CO in which coordinate bond is formed between carbon and oxygen as well as sharing of lone pair present on the oxygen atom.Covalent bonds are formed by sharing of electrons from both the atoms participating in the bond formation.If two atoms from the same element share three pairs of electrons each forming a bond there will be the formation of a triple covalent bond.Therefore, the bond is a triple covalent bond.

Well to my expert knowledge and my exquisite calculations i think the the negative ion # 412 is the key to sucess

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
