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


Sulfuric acid and Sodium hydroxide Hello,you room in right ar to know around the reaction between sulfuric acid and also sodium hydroxide. Sulfuric mountain is an acid since it has actually hydrogen ion.The formula because that sulfuric acid is H₂SO₄.It is a solid acid. Salt hydroxide is a base since it has actually hydroxide ion.The chemistry formula for sodium hydroxide is NaOH.It is a solid base. Check out this:CO Lewis framework                 Sulfuric acid(H2SO4) and also Sodium hydroxide(NaOH)  Acid reacts v base to type salt and water.This type of reaction is referred to as acid basic neutralization reaction. In instance of sulfuric acid and also sodium hydroxide,acid-base neutralization reaction  will happen. Sulfuric mountain reacts with sodium hydroxide and also produce salt sulphate(Na₂SO₄) and water(H₂O).Here  salt sulphate(Na₂SO₄) is a salt beacause that is positive part has come from basic and negative part has come from acid. H₂SO₄ +2  NaOH =Na₂SO₄ +2H₂O i m sorry salt is produced

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


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

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


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

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


August 19, 2018
how to transform Propyne to Propene Propyne reacts with hydrogen (H₂) in presence of  Pd and also BaSO₄ in ~ 25ºc temperature and produce propene(CH₃-CH=CH₂). Below BaSO4 acts as catalyst poison in the direction of Pd catalyst to reduce it's catalytic action and controls the upto an initial stage. How to transform Propene come Propyne          Step-1: Propene(CH₃-CH=CH₂) reacts v Br₂ in presence 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 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.

SO2 Lewis Structure   Answer: below is the definition of SO2 Lewis structure. SO2 Lewis framework (sulfur dioxide electron dot structure) is that type of diagram whereby we present the full 18 valence electron of SO2 as dots , or dots and also dashes(-).In Lewis structure,it is usual that a bonding pair of 2 electrons have the right to be presented by  dash(-) or dots(●●) but a lone pair of two electrons is shown by dots<●●>. In SO2 Lewis structure,there are two twin bonds that space going from the atom sulphur come oxygens. In SO2 Lewis framework ,there are completely five lone bag of electrons.The each  oxygen has two lone pairs of electrons and also the sulphur atom has actually one lone pair of electrons. In SO2 Lewis structure ,the oxygen atoms follow the octet rule however the sulfur atom don't monitor the octet rule.It has more than eight electrons. In SO2 Lewis structure,we obtain nine pairs of electrons.Out of nine pairs the electrons,SO2 has four 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 framework where we show the complete ten valence electron of CO as dots , or dots and also dashes(-).In Lewis structure,it is common that a bonding pair of two electrons deserve to be displayed by  dash(-) or dots(●●) yet a lone pair of two electrons is shown by dots<●●>. CO Lewis structure In CO Lewis structure,the carbon atom follows the octet rule and also the oxygen atom likewise follows the octet rule.So,CO follows the octet dominion for every the atoms. In CO Lewis structure,we get five pairs that electrons.Out of five pairs the electrons,CO has actually three bond pairs and two lone bag of electrons.Here carbon has actually one lone pair and also oxygen has actually one lone pair of electrons.

sodium Hydroxide and Sulfuric Acid well balanced Equation now I will balance sulfuric acid and sodium hydroxide reaction. Step-1:write the reaction. H₂SO₄ + NaOH ----->Na₂SO₄ +H₂O Step-2:In the left side, we have  H SO₄  Na O come balance this reaction means we must equalize the number of these above atoms and also polyatomic ion. Step-3:Now balance Na atom first.In the left hand side,we have actually one Na yet in the appropriate side,we have actually two Na.So come balance Na ,we should put 2 before NaOH in the left side.
