Most likely you will need the periodic table link. VIDEO Types of Chemical Equations Demonstrated Example 4 : Give the type of chemical equation of the reaction below. If you forgot the ions go back to the ions of the periodic table also.Ĭ 3 H 8(l) + 10 O 2(g) -> 3 CO 2(g) + 4 H 2 O (g) VIDEO Types of Chemical Equations Demonstrated Example 3 : Give the type of chemical equation of the reaction below. If 3 on each side: Then it is a SINGLE REPLACEMENT How many different ions can the reaction form on the reactants and products sides of the equation?Īg forms a positive ion ( that is 1 ), P forms a negative ion ( that is 2 ), V forms a positive ion ( that is 3 ) If No: Then it is NOT a decomposition reactionĭoes it have O 2 in its REACTANTS and CO 2 and H 2 O in its PRODUCTS? If you forgot the ions go back to the ions of the periodic table also.Ģ Ag 3P (s) + 3 V (s) -> V 3P 2 (s) + 6 Ag (s)
VIDEO Types of Chemical Equations Demonstrated Example 2 : Give the type of chemical equation of the reaction below. If Yes: Then it is a DECOMPOSTION reaction If you forgot the ions go back to the ions of the periodic table also.Īnswer: Use the flow chart and ask the first question.ĭoes it have 1 chemical on the PRODUCTS side and 2 or more on the REACTANTS side?Īnswer: Follow the NO arrows on the flow chart and ask the next question.ĭoes it have 1 chemical on the REACTANTS side and 2 or more on the PRODUCTS side? VIDEO Types of Chemical Equations Demonstrated Example 1 : Give the type of chemical equation of the reaction below.
#CHEMICAL EQUATION MAKER HOW TO#
Look to the demonstrated example videos and text to understand how to use the flow chart. To do that the best way is to ask questions about the chemical equations in front of you. Below is a picture of the flow chart of the questions and information that allow you to either confirm or deny the different types of chemical equations. You want to be able to identify which one of the 5 types of chemical equations it is. The first kinds of questions you want to be able to answer with the above information is if you are given a complete chemical equation. Why kinds of questions can they ask you about the types of chemical equations? Generic Example: carbon compound + O 2 (g) -> CO 2 (g) + H 2O (g) SINGLE REPLACEMENT (also known as single displacement):ĭefinition: One set of chemical partners swap as they go from reactants to products.Įxample 1: Na (s) + LiF (aq) -> Li (s) + NaF (aq)Įxample 2: 2 Fe(NO 3) 3 (aq) + 3 Be (s) -> 3 Be(NO 3) 2 (s) + 2 Fe (s)Įxample 3: 3 (NH 4) 2(CO 3) (aq) + 2 PO 4 3- (aq) -> 2 (NH 4) 3(PO 4) (aq) + 3 CO 3 2- (aq)ĭOUBLE REPLACEMENT (also known as double displacement):ĭefinition: Two sets of chemical partners swap as they go form reactants to products.Įxample 1: KBr (aq) + LiCl (aq) -> KCl (aq) + LiBr (aq)Įxample 2: 3 MgS (aq) + 2 Cs 3N (aq) -> 3 Cs 2S (aq) + Mg 3N 2 (s)Įxample 3: 2 Al(OH) 3 (aq) + 3 CaSO 4 (aq) -> Al 2(SO 4) 3 (aq) + 3 Ca(OH) 2 (aq)ĭefinition: A carbon compound and oxygen combined to become CO 2 and H 2OĮxample 1: CH 4 (g) + 2 O 2 (g) -> CO 2 (g) + 2 H 2O (g)Įxample 2: C 6H 12O 6 (s) + 6 O 2 (g) -> 6 CO 2 (g) + 6 H 2O (g)Įxample 3: CH3COOH (aq) + 4 O 2 (g) -> 2 CO 2 (g) + 2 H 2O (g)
Use the periodic table or ion periodic table link if you need it.ĭefinition: Two or more chemicals on the reactants become a single chemical on the products.Įxample 1: Na + (aq) + Cl – (aq) -> NaCl (aq)Įxample 2: Ca (s) + Br 2 (g) -> CaBr 2 (s)Įxample 3: 6 C (s) + 6 H 2 (g) + 3 O 2 (g) -> C 6H 12O 6 (s)ĭefinition: One chemical on the reactants becoming two or more on the products.Įxample 1: LiOH (aq) -> Li + (aq) + OH – (aq)Įxample 2: 2 K 2O (s) -> 4 K (s) + O 2 (g)Įxample 3: 2 HCN (aq) -> H 2 (g) + 2 C (s) + N 2 (g) Look at them and see what kind of patterns you can recognize. The different types are below in bold with clear examples. This helps you to predict how different chemicals will react when mixing them. With many chemical equations you can break them down by the type of chemical equation. What are the different types of chemical equations?
