In this video, a Mexican chemist explains the reactions of double substitution. He shows how to combine a positive number with a negative number to get a positive/negative resultant. He also shows how to perform a double displacement and a double replacement.

• 00:00:00 In this video, Mexican chemist explain the reactions of double substitution (a step-by-step easy process). Among the reactions students are familiar with are double displacement (a chemical reaction in which two atoms are moved) and double replacement (a chemical reaction in which two atoms are added). To perform these reactions, we need this formulae, which I will leave for you to download and print. This table has positive and negative values, and the goal is to combine a positive number with a negative number to get a positive/negative resultant. In chemistry, always the first number is called the metal and the second number is called the halogen. For example, what you are seeing on the screen is sodium, iron, copper, and so on. The negative numbers are like the oxygen in the list, and they are called the anions. Here's the trick: always combine positive numbers with negative numbers to get a result. This is the formula students should follow when solving equations. For example, if we have a situation where the beginning number is positive and the end number is negative, we would combine the positive number with the negative number to get the result of the equation. In this case, we would get sodium (the metal) with chlorine (the hal
• 00:05:00 In half of 2011, the 1 wasn't written in chemistry if you don't simplify it. That's wrong. So, in this reaction of double substitution, obtaining these products is to say an exchange of pairs but is usually balanceated which means what that arrow is pointing to. Let's check it out. I have magnesium here and here I have a magnesium2 and then I have two lorans over here but to the right I have a pain. So you have to add the same number if I have here two claros. But these numbers always add up the ones you're gonna put in always add up to the beginning of the formula. They can't go in the middle. They always go to the beginning of the formula where the element is, in this case, the chlorine. I have magnesium and magnesium2 and two claros and two claros and with this two of red already have two moles of sodium and here I have two enemas and finally here I have teluro and to the right teluro and this is the complete equation for selecting for the example number 3. For number 3, we see that it is a reaction of double substitution because this component is a pair and this component is another pair and they will exchange
• 00:10:00 In this video, an equation is shown for the reaction of a double substitution. The equation is shown for the reaction of two zinc atoms, one with a number and one without. The numbers always go at the beginning of the equation and in large font, and you cannot put them in the middle of a 35-atom group. The red train of molecules multiplies also the group of atoms with the same number three times, to be 3 atoms each. For example, in the reaction of the zinc with the number 2, there are 3 atoms of zinc. In the reaction of the zinc with the number 3, there are 6 atoms of zinc. The equation is then rewritten to show that there are now 2 atoms of zinc and 1 atom of zinc. The zinc with the number 2 will then be multiplied by 26 grams and this is the equation for the reaction of the zinc with the number 3: 3 atoms of zinc multiplied by 26 grams. This equation is then rewritten to show that there are now 3 atoms of zinc and 2 atoms of zinc. The zinc with the number 3 will then be multiplied by 3, 6 grams, and this is the equation for the reaction of the zinc with the number 2: 2 atoms of zinc multiplied by 3, 6 grams. The
