Ag has an anomalous electron configuration. write the observed electron configuration of ag. express your answer in complete form in order of increasing orbital energy. for example, 1s22s2 should be entered as 1s^22s^2.

In Silver, the 4d orbitals will be completely filled. That implies that it does not have two electrons in the 5s orbital. The electronic configuration of Silver is :

Ag (47) = 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^1 4d^10

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.
