The central atom doesn’t have eight valence electrons, so what’s drawn in part B isn’t yet a stable molecule and can’t represent the actual structure of ozone. An additional bond must be made to complete the full set of valence electrons on the central atom. This can be done by removing a lone pair of electrons from either one of the outer atoms and using it to make an additional bond between that atom and the central atom. Redraw the Lewis structure you drew in part B and show this additional bond.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

its first and third is your answer i did the qustion the fourth isnt right

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.
