Is -4 a Rational Number?

Today we will determine whether -4 is a rational number or not in just four steps.

                  

                       Step-1: 

A rational number is like p/q.Here p and q are Integers and q is not zero.
*Rational Number=p÷q

   Condition:q is not zero.
Is -4 a Rational Number

                   Step-2:

 Notice that 1 can be expressed as 1/1.The value of  both 1/1 and 1 is the same which is 1.
Therefore,1=1/1


                         Step-3:
Now we will consider -4.

 -4 can be written as -4/1 or -4÷1
Therefore, -4 = -4/1
                   Step-4:

 We know that the fraction or ratio p/q is a rational number.As we can express -4 as -4/1,so -4 is a rational number (p/q,here q=1,p=-4)

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.

【】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 electron...
