【】How Many Valence Electrons Does Selenium (Se) Have?|| Selenium (Se) Valence Electrons

Image
Selenium has six valence electrons. Read:CO2 Lewis Structure Explanation: Now I am going to show you how to find valence electrons in selenium  in just 5 steps. Add caption              Step-1: First, find the atomic number of  selenium  from periodic table. From periodic table ,we see that the atomic number of  selenium  is 34.                  Step-2: We know that the atomic number of  selenium  is 34.So  selenium  has 34 protons and 34 electrons as the charge of electrons and protons are equal but opposite in nature.The charge of proton is +1 and the charge of electron is -1. Read:CO2 Lewis Structure                 Step-3: Now write the electron configuration of  selenium   . Se(34)=1s²2s²2p⁶3s²3p⁶4s²3d¹º4p⁴ Rewrite this from low to high value of n. Se(34)=1s²2s²2p⁶3s²3p⁶ 3d¹º 4s² 4p⁴ Read:CO2 Lewis Structure                 Step-4: Se(34)=1s²2s²2p⁶3s²3p⁶ 3d¹º 4s² 4p⁴

Sulfuric acid and Sodium hydroxide Hello,you are in right place to know about the reaction between sulfuric acid and sodium hydroxide. Sulfuric acid is an acid because it has hydrogen ion.The formula for sulfuric acid is H₂SO₄.It is a strong acid. Sodium hydroxide is a base because it has hydroxide ion.The chemical formula for sodium hydroxide is NaOH.It is a strong base. Read this:CO Lewis Structure Read:CO2 Lewis Structure                 Sulfuric acid(H2SO4) and Sodium hydroxide(NaOH)  Acid reacts with base to form salt and water.This type of reaction is called acid base neutralization reaction. In case of sulfuric acid and sodium hydroxide,acid-base neutralization reaction  will happen. Sulfuric acid reacts with sodium hydroxide and produce sodium sulphate(Na₂SO₄) and water(H₂O).Here  sodium sulphate(Na₂SO₄) is a salt beacause its positive part has come from base and negative part has come from acid. This is a balanced equation: H₂SO₄

【】How to Convert Ethene to Ethanoic Acid or Acetic Acid||How Ethanoic Acid Is Prepared from Ethene

Image
Answer: To convert ethene to ethanoic acid,we will adopt four steps:              Step-1: Ethene reacts with HBr and we get 1-bromo ethane.            Step-2: 1-bromo ethane reacts with aqueous KOH and we get ethanol.            Step-3: Ethanol is oxidized by K₂Cr₂O₇ plus H₂SO₄ and we get ethanal.            Step-4: Again,ethanal is oxidized by K₂Cr₂O₇ plus H₂SO₄ and we get ethanoic acid or acetic acid. Now see all the steps at a glance.

How to Convert Propyne to Propene Propyne reacts with hydrogen (H₂) in presence of  Pd and BaSO₄ at 25ºc temperature and produce propene(CH₃-CH=CH₂). Here BaSO4 acts as catalyst poison towards Pd catalyst reducing it's catalytic action and controls the upto first stage. How to Convert Propene to Propyne          Step-1: Propene(CH₃-CH=CH₂) reacts with Br₂ in presence 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 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: Here is the definition of SO2 Lewis structure. SO2 Lewis structure (sulfur dioxide electron dot structure) is that type of diagram where we show the total 18 valence electrons of SO2 as dots , or dots and dashes(-).In Lewis structure,it is common that a bonding pair of two electrons can be shown by  dash(-) or dots(●●) but a lone pair of two electrons is shown by dots[●●]. In SO2 Lewis structure,there are two double bonds that are 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 pairs of electrons and the sulphur atom has one lone pair of electrons. In SO2 Lewis structure ,the oxygen atoms follow the octet rule but 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 pairs of electrons.Here,each oxy

Sodium Hydroxide and Sulfuric Acid 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 To balance this reaction means 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 one Na but in the right side,we have two Na.So to balance Na ,we need to put 2 before NaOH in the left side. H₂SO₄ +2 NaOH ----->Na₂SO₄ + H₂O Step-3:Now balance H. After step 3 we are getting ... H₂SO₄ +2 NaOH ----->Na₂SO₄ + H₂O In the left hand side,we have 4 hydrogens but in the right side ,we have 2 hydrogen's.So we need to place 2 before  H₂O in the right side. So we are getting... H₂SO₄ +2 NaOH ----->Na₂SO₄ +2 H₂O Step-4:Now balance SO4  Ater step 3, we are getting... H₂SO₄ +2 NaOH ----->Na₂SO₄ +2 H₂O In the left side ,we have one  SO₄   and in the
