【●】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 place to know about the reaction in between sulfuric acid and also sodium hydroxide. Sulfuric acid is an acid due to the fact that it has actually hydrogen ion.The formula because that sulfuric mountain is H₂SO₄.It is a solid acid. Sodium hydroxide is a base due to the fact that it has hydroxide ion.The chemical formula for sodium hydroxide is NaOH.It is a solid base. Read this:CO Lewis structure                 Sulfuric acid(H2SO4) and also Sodium hydroxide(NaOH)  Acid reacts with base to type salt and water.This form of reaction is referred to as acid base neutralization reaction. In case of sulfuric acid and sodium hydroxide,acid-base neutralization reaction  will happen. Sulfuric mountain reacts through sodium hydroxide and produce salt sulphate(Na₂SO₄) and water(H₂O).Here  sodium sulphate(Na₂SO₄) is a salt beacause that positive component has come from basic and negative part has come native acid. H₂SO₄ +2  NaOH =Na₂SO₄ +2H₂O which salt is produced

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


Hydrochloric Acid and Sodium Hydroxide Hello,you are in right place to know around the reaction between hydrochloric acid and sodium hydroxide. Hydrochloric acid is an acid since it has hydrogen ion.The formula because that hydrochloric mountain is HCl.It is a solid acid. Salt hydroxide is a base because it has actually hydroxide ion.The chemistry formula for salt hydroxide is NaOH.It is a strong base. Hydrochloric acid (HCl) and also Sodium hydroxide(NaOH) acid reacts through base to type salt and water.This type of reaction is dubbed acid base neutralization reaction. In situation of hydrochloric acid and also sodium hydroxide,acid-base neutralization reaction will happen. Hydrochloric acid reacts with sodium hydroxide and produce sodium chloride(NaCl) and also water(H₂O).Here salt chloride(NaCl) is a salt beacause the 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 balanced Equation currently I will certainly balance hydrochlor

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


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

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


August 19, 2018
just how to convert Propyne come Propene Propyne reacts v hydrogen (H₂) in existence of  Pd and also BaSO₄ in ~ 25ºc temperature and also produce propene(CH₃-CH=CH₂). Here BaSO4 acts together catalyst poison towards Pd catalyst reducing it's catalytic action and controls the upto an initial stage. How to transform Propene to Propyne          Step-1: Propene(CH₃-CH=CH₂) reacts with Br₂ in existence of CCl₄ and produce 1,2-dibromo propane( CH₃-CH(Br)CH₂Br).             Step-2: 1,2-dibromo propane( CH₃-CH(Br)CH₂Br) reacts with (alc)KOH and also 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: right here is the an interpretation of SO2 Lewis structure. SO2 Lewis framework (sulfur dioxide electron dot structure) is that type of diagram where we present the complete 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 shown by  dash(-) or dots(●●) but a lone pair of 2 electrons is displayed by dots<●●>. In SO2 Lewis structure,there are two twin bonds that room going from the atom sulphur to oxygens. In SO2 Lewis structure ,there are totally five lone bag of electrons.The each  oxygen has two lone bag of electrons and the sulphur atom has one lone pair that electrons. In SO2 Lewis structure ,the oxygen atoms follow the octet rule but the sulfur atom don't monitor the octet rule.It has much more than eight electrons. In SO2 Lewis structure,we obtain nine pairs 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 framework Answer: CO Lewis structure(carbon monoxide electron dot structure) is that type of framework where we present the full ten valence electron of CO as dots , or dots and also dashes(-).In Lewis structure,it is usual that a bonding pair of 2 electrons can be shown by  dash(-) or dots(●●) but a lone pair of 2 electrons is presented by dots<●●>. CO Lewis structure In CO Lewis structure,the carbon atom complies with the octet rule and also the oxygen atom likewise follows the octet rule.So,CO adheres to the octet ascendancy for all the atoms. In CO Lewis structure,we get five pairs of electrons.Out of five pairs that electrons,CO has actually three link pairs and two lone bag of electrons.Here carbon has one lone pair and also oxygen has one lone pair the electrons.

salt 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 to balance this reaction way we need to equalize the number of these above atoms and polyatomic ion. Step-3:Now balance Na atom first.In the left hand side,we have actually one Na yet in the right side,we have two Na.So come balance Na ,we should put 2 prior to NaOH in the left side. H₂SO₄ +2 NaOH ----->Na₂SO₄ + H₂O Step-3:Now balance H. After step 3 us are getting ... H₂SO₄ +2 NaOH ----->Na₂SO₄ + H₂O In the left hand side,we have 4 hydrogens but in the ideal side ,we have actually 2 hydrogen's.So we require to ar 2 before  H₂O in the right side. Therefore we room getting... H₂SO₄ +2 NaOH ----->Na₂SO₄ +2 H₂O Step-4:Now balance SO4  Ater step 3, we space getting...
