【】 C6H12O6 Valence Electrons ||How many valence electrons are there in a glucose molecule

How many valence electrons does C6H12O6 (glucose) have ? Answer : In C₆H₁₂O₆ ,we get 6 carbon atoms , 12 hydrogen atoms and 6 oxygen atoms. Firstly, carbon is an element of group 4A,so it has 4 valence electrons. Secondly,Hydrogen is an element of group 1A.So it has one valence electrons. Thirdly, oxygen is an element of group 6A .So it has six valence electrons. For C₆H₁₂O₆ , 6 C = 6 × 4 = 24 12 H =12 × 1 =12 6 O = 6 ×6 = 36 Totally, we are getting 24 + 12 + 36 = 72 valence electrons in glucose (C6H12O6). Next

【】Sodium Hydroxide and Sulfuric Acid Balanced Equation||Balanced Chemical Equation for Sulfuric Acid And Sodium Hydroxide

February 25, 2020

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

How to calculate the formal charge of CO2

January 12, 2022

The formal charge of carbon(C) and oxygen(O) in CO2 is zero. Explanation: In this post,I am going to show you how to calculate formal charge of each atom in CO2. To find the formal charge of a atom from CO2 Lewis structure,you need to apply the following formal charge formula or equation : ●Formal charge = Valence electrons in neutral atom - 1/2 (Bonding Electrons) - Nonbonding electrons Now consider the best Lewis structure of CO2 molecule.Here you need to calculate the formal charge of oxygen atom and carbon atom. How to calculate the formal charge of CO2 Formal charge of O atom in CO2: ●The number of valence electrons in a neutral oxygen atom is 6 as it is the element of group VIA. ●Nonbonding electrons of O is 4. ●Bonding electrons of O is 4. ● Formal charge of O = Valence electrons in neutral O atom - 1/2 (Bonding Electrons of O) -Nonbonding elctrons of O =6 - 1/2(4) - 4 =6 -2 -4 =6-6 =0 So,the formal ch

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

February 14, 2019

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

December 15, 2018

CO Lewis Structure Answer: CO Lewis structure(carbon monoxide electron dot structure) is that type of structure where we show the total ten valence electrons of CO 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[●●]. CO Lewis Structure In CO Lewis structure,the carbon atom follows the octet rule and the oxygen atom also follows the octet rule.So,CO follows the octet rule for all the atoms. In CO Lewis structure,we get five pairs of electrons.Out of five pairs of electrons,CO has three bond pairs and two lone pairs of electrons.Here carbon has one lone pair and oxygen has one lone pair of electrons. Explanation: Today we are going to learn to draw CO Lewis structure (Carbon monoxide Lewis structure) in just few steps. CO Lewis Structure CO Lewis Structure Setup Steps There are 5 steps that you need to follow when drawing the C

【】How to Draw Lewis Dot Structure

December 16, 2018

Hello, Everyone! today we are going to know how to draw Lewis structure or Lewis dot diagrams for atoms,ions and simple molecules. How to find out valence electrons of an element? Before I begin, I would like to ask you a question:how many valence electrons does chlorine have? For getting the answer of that question we need to look at the periodic table. Notice that within any given column all the elements have the same number of valence electron. To get valence electron's number, all we have to do is to count the columns starting from left.Skip the transition metals and bear in mind that the only exception to this is helium atom, which has only 2 valence electrons(duet) ,not 8. Now find chlorine in the periodic table. Remember that Chlorine's symbol is Cl. See it in the 7th column. That indicates us that it has 7 valence electrons. If you do electronic configuration of chlorine, then you will see that the outermost shell has

【】H2CCH2 Lewis Structure ,Valence Electrons ,Formal Charge

H2CCH2 Lewis structure Answer: In H2CCH2 Lewis Dot structure ,two double bonds exist between the two carbon atoms.Besides,each carbon has two hydrogen atoms using two single bonds.In H2CCH2 Lewis Dot structure,there are totally twelve valence electrons. Explanation: Hello,today I am going to draw the H2CCH2 Lewis structure in just few steps. H2CCH2 Lewis structure Setup Step-1: To draw the CH2CH2 lewis structure , we have to find out the H2CCH2 valence electrons first.We express valence electrons as dots in CH2CH2 lewis dot structure. To get the valence electrons of carbon,we need to look at the electronic configuration of carbon. C(6)=1s²2s²2p² The highest value of principal quantum number here is n=2. The highest value of principal quantum number ,n , indicates the valence shell and we know the electrons in valence shell is called valence shell. The nunber of valence electrons in carbon is 4. Now,to draw the lewis dot structure of carbon,we need to imagine a square aroun

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

September 04, 2018

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.

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
