How many valence electrons does selenium (Se) have? Answer: Selenium has six valence electrons. Explanation: currently we are going come know  how many  valence electrons  selenium  have in just 5 steps. Include caption              Step-1: First, discover the atomic number of  selenium  from routine table. From periodic table ,we check out that the atomic number of  selenium  is 34.                  Step-2: We understand that the atom number of  selenium  is 34.So  selenium  has 34 protons and 34 electrons together the fee of electrons and protons room equal but opposite in nature.The fee of proton is +1 and also the charge of electron is -1.                 Step-3: currently write the electron configuration of  selenium   . Se(34)=1s²2s²2p⁶3s²3p⁶4s²3d¹º4p⁴ Rewrite this from short to high worth of n. Se(34)=1s²2s²2p⁶3s²3p⁶ 3d¹º 4s² 4p⁴                 Step-4: Se(34)=1s²2s²2p⁶3s²3p⁶ 3d¹º

Sulfuric acid and Sodium hydroxide Hello,you space in right location to know about the reaction in between sulfuric acid and sodium hydroxide. Sulfuric mountain is one acid since it has actually hydrogen ion.The formula because that sulfuric acid is H₂SO₄.It is a strong acid. Salt hydroxide is a base due to the fact that it has actually hydroxide ion.The chemical formula for sodium hydroxide is NaOH.It is a strong base. Review this:CO Lewis framework                 Sulfuric acid(H2SO4) and also Sodium hydroxide(NaOH)  Acid reacts v base to type salt and water.This form of reaction is dubbed acid base neutralization reaction. In situation of sulfuric acid and also sodium hydroxide,acid-base neutralization reaction  will certainly happen. Sulfuric mountain reacts through sodium hydroxide and produce sodium sulphate(Na₂SO₄) and also water(H₂O).Here  salt sulphate(Na₂SO₄) is a salt beacause that is positive component has come from base and negative part has come native acid. H₂SO₄ +2  NaOH =Na₂SO₄ +2H₂O i beg your pardon salt is produced

Hydrochloric Acid and Sodium Hydroxide Hello,you are in right place to know around the reaction in between hydrochloric acid and also sodium hydroxide. Hydrochloric acid is an acid because it has hydrogen ion.The formula for hydrochloric acid is HCl.It is a strong acid. Salt hydroxide is a base due to the fact that it has actually hydroxide ion.The chemical formula for sodium hydroxide is NaOH.It is a solid base. Hydrochloric acid (HCl) and also Sodium hydroxide(NaOH) mountain reacts with base to kind salt and also water.This type of reaction is referred to as acid basic neutralization reaction. In instance of hydrochloric acid and sodium hydroxide,acid-base neutralization reaction will certainly happen. Hydrochloric mountain reacts through sodium hydroxide and also produce salt chloride(NaCl) and also water(H₂O).Here sodium chloride(NaCl) is a salt beacause that is positive part (Na+)has come from base and an adverse part(Cl-) has actually come native acid. HCl+ NaOH =NaCl +H₂O Hydrochloric Acid and Sodium Hydroxide well balanced Equation now I will certainly balance hydrochlor

【】How to transform Ethene come Ethanoic acid or Acetic Acid||How Ethanoic mountain Is prepared from Ethene


How to transform Ethene to Ethanoic mountain or Acetic mountain Answer: To transform ethene to ethanoic acid,we will take on four steps:              Step-1: Ethene reacts through HBr and also we get 1-bromo ethane.            Step-2: 1-bromo ethane reacts through aqueous KOH and also we obtain ethanol.            Step-3: Ethanol is oxidized by K₂Cr₂O₇ plus H₂SO₄ and we acquire ethanal.            Step-4: Again,ethanal is oxidized through K₂Cr₂O₇ to add H₂SO₄ and we acquire ethanoic acid or acetic acid. Currently see every the actions at a glance.

SO2 Lewis Structure   Answer: below is the definition of SO2 Lewis structure. SO2 Lewis structure (sulfur dioxide electron dot structure) is that kind of diagram where we present the full 18 valence electron of SO2 together dots , or dots and dashes(-).In Lewis structure,it is usual that a bonding pair of 2 electrons have the right to be presented by  dash(-) or dots(●●) yet a lone pair of 2 electrons is shown by dots<●●>. In SO2 Lewis structure,there space two twin bonds that are going indigenous the atom sulphur to oxygens. In SO2 Lewis structure ,there are completely five lone pairs of electrons.The each  oxygen has actually two lone bag of electrons and also the sulphur atom has actually one lone pair the electrons. In SO2 Lewis framework ,the oxygen atom follow the octet rule however the sulfur atom don't monitor the octet rule.It has much more than eight electrons.
