How countless valence electron does selenium (Se) have? Answer: Selenium has six valence electrons. Explanation: now we are going come know  exactly how many  valence electrons  selenium  have in simply 5 steps. Include caption              Step-1: First, uncover the atom number of  selenium  from routine table. From periodic table ,we see that the atom number of  selenium  is 34.                  Step-2: We know that the atom number of  selenium  is 34.So  selenium  has 34 protons and also 34 electrons as the charge of electrons and also protons are equal yet opposite in nature.The charge of proton is +1 and the charge of electron is -1.                 Step-3: currently write the electron construction 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 also Sodium hydroxide Hello,you are in right place to know about the reaction in between sulfuric acid and sodium hydroxide. Sulfuric mountain is one acid because it has actually hydrogen ion.The formula for sulfuric acid is H₂SO₄.It is a solid acid. Sodium hydroxide is a base since it has hydroxide ion.The chemical formula for salt hydroxide is NaOH.It is a strong base. Review this:CO Lewis structure                 Sulfuric acid(H2SO4) and Sodium hydroxide(NaOH)  Acid reacts with base to kind salt and water.This form of reaction is dubbed acid base neutralization reaction. In instance of sulfuric acid and sodium hydroxide,acid-base neutralization reaction  will certainly happen. Sulfuric mountain reacts through sodium hydroxide and also produce salt sulphate(Na₂SO₄) and also water(H₂O).Here  sodium sulphate(Na₂SO₄) is a salt beacause its positive component has come from basic and an adverse part has actually come indigenous acid. H₂SO₄ +2  NaOH =Na₂SO₄ +2H₂O i m sorry salt is produced

Hydrochloric Acid and Sodium Hydroxide Hello,you room in right place to know around the reaction between hydrochloric acid and sodium hydroxide. Hydrochloric acid is one acid due to the fact that it has actually hydrogen ion.The formula because that hydrochloric mountain is HCl.It is a solid acid. Sodium hydroxide is a base since it has hydroxide ion.The chemistry formula for salt hydroxide is NaOH.It is a solid base. Hydrochloric acid (HCl) and Sodium hydroxide(NaOH) mountain reacts through base to type salt and also water.This form of reaction is called acid base neutralization reaction. In instance of hydrochloric acid and sodium hydroxide,acid-base neutralization reaction will certainly happen. Hydrochloric acid reacts v sodium hydroxide and produce sodium chloride(NaCl) and water(H₂O).Here sodium chloride(NaCl) is a salt beacause that positive component (Na+)has come from basic and negative part(Cl-) has come native acid.

just how to convert Propyne to Propene Propyne reacts through hydrogen (H₂) in presence of  Pd and BaSO₄ in ~ 25ºc temperature and also produce propene(CH₃-CH=CH₂). Below BaSO4 acts together catalyst poison towards Pd catalyst reduce it's catalytic activity and controls the upto an initial stage. Exactly how to convert Propene to Propyne          Step-1: Propene(CH₃-CH=CH₂) reacts with Br₂ in existence of CCl₄ and also produce 1,2-dibromo propane( CH₃-CH(Br)CH₂Br).             Step-2: 1,2-dibromo propane( CH₃-CH(Br)CH₂Br) reacts through (alc)KOH and produce 1-bromo propene-1(CH₃-CH=CH-Br).                        Step-3: 1-bromo propene-1(CH₃-CH=CH-Br) reacts v sodamide and also produce propyne.

SO2 Lewis Structure   Answer: here is the meaning of SO2 Lewis structure. SO2 Lewis framework (sulfur dioxide electron period structure) is that type of diagram where we show the total 18 valence electrons of SO2 together dots , or dots and dashes(-).In Lewis structure,it is typical that a bonding pair of two electrons can be shown by  dash(-) or dots(●●) yet a lone pair of two electrons is presented by dots<●●>. In SO2 Lewis structure,there are two double bonds that space going from the atom sulphur to oxygens. In SO2 Lewis structure ,there are totally five lone pairs of electrons.The each  oxygen has two lone bag of electrons and also the sulphur atom has actually 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 more than eight electrons. In SO2 Lewis structure,we get nine pairs of electrons.Out of nine pairs of electrons,SO2 has four bond pairs of electrons and five lone bag of electrons.Here,each oxy
