The spectrum of an atom consists of a continuous set of wavelengths which are emitted or absorbed by the atom. consists of an infinite number of wavelengths that can be emitted or absorbed by the atom. can only be explained by quantum mechanics, which states that electrons may only orbit nuclei in discrete orbits. is fully explained by 19th century physics.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

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.

you gotta add the following molecules so we can give u an answer
