Soved which of the following statements regarding orbitals is correct? multiple choice o a picture of an n= 1 bohr orbit would look the same as a picture of a sorbital. o the d'orbitals always come in sets of four. 0 the sorbitals always have two lobes. 0 an orbital can hold four electrons. a 2 orbital is lower in energy than a 3p orbita

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
