Mnemonic for Electrochemical Series

Mnemonics For Electrochemical Series

SHORTCUT TO THE ELECTROCHEMICAL SERIES

Hello again. I am back with a new blog. Its not because I need to but because I couldn't resist writing one. I'll provide you a simple mnemonic for remembering THE ELECTROCHEMICAL SERIES.

A series of elements we come across time and often. And a must memorize part of High School. Remember the time you woke up whole night remembering it and the next morning the elements go upside down. The next day you bought a huge chart and stick on your bedroom but still had the confusions. Now Now dont worry I'll provide you with a sentance to remember it.Details below:

Remember: Electrode potentials are reduction potential at 298K.
Now the sentence is LITTLE POP BARRY CANADIAN STAR MADE ALL ZEBRAS IN TOWN LIKE HIS CAR. COME MY SISTER PLAY GOLF .Practice this and u will b perfect in no time.

now lets talk in brief about its application

  • Calculation of standard cell potential by Ecathode-Eanode. Remember First element in series become anode.
  • Predict oxidizing and reducing agent. lithium is strongest Reducing agent in solution.Remember Oxidizing agent undergo reduction at Cathode and Reducing agent undergo oxidation at anode. If u r still confuse which occurs where, then i have the solution of that too. Remember two animals RED CAT(Reduction cathode) and AN OX(Oxidation anode).
  • Predict dirextion of displacement. Upper in Series displace the lower one from their solution. Thats why u cannot stir copper sulphate solution with zinc spatula.
  • Metals above hydrogen can form the gas when treated with non oxidising acid.

Elements on Left side except copper can form Hydrogen.

Remember this few tips and ur perfect. That's its folks. See u next time. Ans at last


do hit those like and suscribe buttons I appreciate it.

How to Prove 1+1=11?

We all know that one on adding with one equals two. Even a kid can give you this answer. It is because we are taught this way and probably the first addition we begin with in our life. This is the basic we set our mind with. What if we were told 1 + 1 = 11 from the beginning? Then the whole mathematics would be in different way. Here lets just focus on 1 + 1 ... To prove 1 + 1 = 11 Step 1:     -22 = -22 Step 2:     4 - 26 = 121 - 143 Step 3:     2 2 - 2×2×(13/2) = 11 2 - 2×11×(13/2) Step 4:     2 2 - 2×2×(13/2) + (13/2) 2 = 11 2 - 2×11×(13/2) + (13/2) 2 Step 5:     (2 - 13/2) 2 = (11 - 13/2) 2 Step 6:     2 - 13/2 = 11 - 13/2 Step 7:     2 = 11 Step 8:     1 + 1 = 11 Explanation Step 1: I know you must be thinking how do i know which number to begin with. The trick is always to take a negative number . To get the number, you need to add the numbers on the left and multiply with the number on the right. Here we have (1 + 1) × 11 which equals 22. Step 2:

ICD 11 CODING

 ICD-11 stands for International Classification of Diseases 11th Revision, and it is the global standard for diagnostic health information. The ICD-11 coding tool is a web-based application that helps you code with ICD-11 in a fast and accurate way. In this video, i will show you how to use the coding tool, how to search for codes, how to enter multiple conditions, how to use the terminology coding and rare diseases coding features. By the end of this video, you will be able to use the ICD-11 coding tool for mortality and morbidity statistics (MMS) with confidence and ease. For more information, please visit the ICD-11 website https://icd.who.int/en or the coding tool website https://icd.who.int/ct11/icd11_mms/en/release.  Thank you for watching and let’s get started! To use the coding tool, you need to enter the condition or diagnosis that you want to code in the search box. For example, let’s say you want to code for acute appendicitis. You can type it in the search box and press ent
