【●】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 are in right ar to know around the reaction in between sulfuric acid and sodium hydroxide. Sulfuric acid is one acid since it has actually hydrogen ion.The formula for sulfuric mountain is H₂SO₄.It is a solid acid. Salt hydroxide is a base because it has actually hydroxide ion.The chemical formula for salt hydroxide is NaOH.It is a solid base. Check out this:CO Lewis structure                 Sulfuric acid(H2SO4) and also Sodium hydroxide(NaOH)  Acid reacts v base to type salt and also water.This kind of reaction is called acid basic neutralization reaction. In situation 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 the positive part has come from basic and negative part has come indigenous acid. H₂SO₄ +2  NaOH =Na₂SO₄ +2H₂O i m sorry salt is produced

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

【】How to transform Ethene to Ethanoic acid or Acetic Acid||How Ethanoic mountain Is all set from Ethene


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

【】How to transform propene come propyne and propyne come propene conversion


August 19, 2018
exactly how to convert Propyne come Propene Propyne reacts v hydrogen (H₂) in visibility of  Pd and also BaSO₄ in ~ 25ºc temperature and produce propene(CH₃-CH=CH₂). Here BaSO4 acts together catalyst poison towards Pd catalyst reducing it's catalytic activity and controls the upto an initial stage. How to convert Propene come Propyne          Step-1: Propene(CH₃-CH=CH₂) reacts with Br₂ in visibility of CCl₄ and also 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 produce propyne.

SO2 Lewis Structure   Answer: below is the definition of SO2 Lewis structure. SO2 Lewis structure (sulfur dioxide electron period structure) is that kind of diagram whereby we present the total 18 valence electron of SO2 together dots , or dots and dashes(-).In Lewis structure,it is typical that a bonding pair of 2 electrons have the right to be presented by  dash(-) or dots(●●) but a lone pair of 2 electrons is presented by dots<●●>. In SO2 Lewis structure,there room two dual bonds that space going from the atom sulphur to oxygens. In SO2 Lewis structure ,there are entirely five lone pairs of electrons.The each  oxygen has actually two lone pairs of electrons and the sulphur atom has one lone pair the electrons. In SO2 Lewis framework ,the oxygen atoms follow the octet rule yet the sulfur atom don't follow the octet rule.It has much more than eight electrons. In SO2 Lewis structure,we get nine bag of electrons.Out of ripe pairs the electrons,SO2 has four bond bag of electrons and also five lone pairs 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 electron of CO as dots , or dots and dashes(-).In Lewis structure,it is common that a bonding pair of 2 electrons deserve to be presented by  dash(-) or dots(●●) but a lone pair of two electrons is presented by dots<●●>. CO Lewis structure In CO Lewis structure,the carbon atom follows the octet rule and also the oxygen atom also follows the octet rule.So,CO complies with the octet dominance for every the atoms. In CO Lewis structure,we get 5 pairs of electrons.Out of five pairs of electrons,CO has three link pairs and also two lone bag of electrons.Here carbon has actually one lone pair and also oxygen has actually one lone pair that electrons.

【 】Sodium Hydroxide and also Sulfuric Acid well balanced Equation||Balanced chemistry Equation for Sulfuric Acid and Sodium Hydroxide


sodium Hydroxide and also Sulfuric Acid balanced Equation now I will balance sulfuric acid and also 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 method we should equalize the number of these over atoms and polyatomic ion. Step-3:Now balance Na atom first.In the left hand side,we have actually one Na yet in the ideal side,we have actually two Na.So to balance Na ,we should put 2 prior to NaOH in the left side. H₂SO₄ +2 NaOH ----->Na₂SO₄ + H₂O Step-3:Now balance H. After action 3 us are acquiring ... H₂SO₄ +2 NaOH ----->Na₂SO₄ + H₂O In the left hand side,we have actually 4 hydrogens yet in the appropriate side ,we have 2 hydrogen's.So we need to location 2 before  H₂O in the appropriate side. For this reason we are getting... H₂SO₄ +2 NaOH ----->Na₂SO₄ +2 H₂O Step-4:Now balance SO4  Ater action 3, we space getting...
