We recognize that the atomic number ofseleniumis 34.Soseleniumhas 34 protons and also 34 electrons together the fee of electrons and also protons space equal but opposite in nature.The fee of proton is +1 and also the fee of electron is -1.
Se(34)=1s²2s²2p⁶3s²3p⁶4s²3d¹º4p⁴Rewrite this from short to high worth of n.Se(34)=1s²2s²2p⁶3s²3p⁶3d¹º4s²4p⁴

【●】H2SO4 + NaOH ||Sulfuric acid(H2SO4) and Sodium hydroxide(NaOH)--What is the reaction between sulfuric acid and sodium hydroxide?


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

【 】Hydrochloric Acid and Sodium Hydroxide||Balanced Equation for Hydrochloric acid and also Sodium Hydroxide


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

【】How to convert Ethene to Ethanoic acid or Acetic Acid||How Ethanoic acid Is prepared from Ethene


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

【】How to convert propene to propyne and propyne to propene conversion


August 19, 2018
exactly how to convert Propyne to Propene Propyne reacts with hydrogen (H₂) in presence of  Pd and BaSO₄ in ~ 25ºc temperature and produce propene(CH₃-CH=CH₂). Here BaSO4 acts as catalyst poison towards Pd catalyst to reduce it's catalytic action and controls the upto very first stage. Exactly how to transform Propene to Propyne          Step-1: Propene(CH₃-CH=CH₂) reacts through Br₂ in visibility of CCl₄ and produce 1,2-dibromo propane( CH₃-CH(Br)CH₂Br).             Step-2: 1,2-dibromo propane( CH₃-CH(Br)CH₂Br) reacts v (alc)KOH and produce 1-bromo propene-1(CH₃-CH=CH-Br).                        Step-3: 1-bromo propene-1(CH₃-CH=CH-Br) reacts with sodamide and also produce propyne.

October 27, 2019
SO2 Lewis Structure   Answer: here is the definition of SO2 Lewis structure. SO2 Lewis structure (sulfur dioxide electron dot structure) is that form of diagram wherein we present the total 18 valence electron of SO2 as dots , or dots and dashes(-).In Lewis structure,it is typical that a bonding pair of 2 electrons have the right to be displayed by  dash(-) or dots(●●) yet a lone pair of two electrons is shown by dots<●●>. In SO2 Lewis structure,there space two dual bonds that room going indigenous 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 the sulphur atom has actually one lone pair of electrons. In SO2 Lewis framework ,the oxygen atoms follow the octet rule however the sulfur atom don't follow the octet rule.It has much more than eight electrons. In SO2 Lewis structure,we obtain nine pairs of electrons.Out of ripe pairs that electrons,SO2 has 4 bond pairs of electrons and also five lone bag of electrons.Here,each oxy

  CO Lewis structure Answer: CO Lewis structure(carbon monoxide electron dot structure) is that type of structure where we show the full ten valence electrons of CO as dots , or dots and dashes(-).In Lewis structure,it is usual that a bonding pair of 2 electrons have the right to be displayed by  dash(-) or dots(●●) yet a lone pair of 2 electrons is presented by dots<●●>. CO Lewis framework In CO Lewis structure,the carbon atom complies with the octet rule and also the oxygen atom likewise follows the octet rule.So,CO follows the octet ascendancy for all the atoms.
