SO2 Lewis Structure   Answer: below is the definition of SO2 Lewis structure. SO2 Lewis framework (sulfur dioxide electron period structure) is that type of diagram whereby we present the complete 18 valence electrons of SO2 as dots , or dots and also dashes(-).In Lewis structure,it is usual that a bonding pair of two electrons deserve to be shown by  dash(-) or dots(●●) but a lone pair of 2 electrons is presented by dots<●●>. In SO2 Lewis structure,there room two double bonds that are going from the atom sulphur to oxygens. In SO2 Lewis framework ,there are completely five lone bag of electrons.The each  oxygen has two lone bag of electrons and also the sulphur atom has one lone pair that electrons. In SO2 Lewis framework ,the oxygen atoms follow the octet rule yet the sulfur atom don't follow the octet rule.It has an ext than eight electrons. In SO2 Lewis structure,we acquire nine pairs of electrons.Out of ripe pairs of electrons,SO2 has four bond pairs of electrons and also five lone bag of electrons.Here,each oxy

sodium Hydroxide and Sulfuric Acid balanced Equation currently I will certainly balance sulfuric acid and sodium hydroxide reaction. Step-1:write the reaction. H₂SO₄ + NaOH ----->Na₂SO₄ +H₂O Step-2:In the left side, we have actually  H SO₄  Na O come balance this reaction way we need to equalize the number of these over atoms and also polyatomic ion. Step-3:Now balance Na atom first.In the left hand side,we have actually one Na but in the right side,we have actually two Na.So to balance Na ,we should put 2 before NaOH in the left side. H₂SO₄ +2 NaOH ----->Na₂SO₄ + H₂O Step-3:Now balance H. After action 3 us are getting ... H₂SO₄ +2 NaOH ----->Na₂SO₄ + H₂O In the left hand side,we have 4 hydrogens but in the right side ,we have actually 2 hydrogen's.So we need to ar 2 before  H₂O in the best side. Therefore we room getting... H₂SO₄ +2 NaOH ----->Na₂SO₄ +2 H₂O Step-4:Now balance SO4  Ater step 3, we are getting...
