Condensation Theory. thought I've heard it be called the condensation-nebula theory.
Answer:
elecreonegativity is the attraction of a bonded atom for the pair of electrons in a covalent bond. this can occur if:
- the nuclear charges are different
- the atoms are different sizes
- the shared pair of electrons are closer to one nucleus than the other
Answer:
Stoichiometric Calculation:
3 NO₂(g) + H₂O (l) → 2 HNO₃(g) + NO(g)
2 moles of HNO₃ is produced from 3 moles of NO₂.
Therefore, By unitary method:
2.30 moles of HNO₃ produced from the moles of NO₂ =
