Chemical Reactions. 8 th Grade Science T. Trimpe http://sciencespot.net/. Watch the movie and then complete the chart. Two or more elements or compounds combine to make a more complex substance. A + B → AB. AB → A + B. Compounds break down into simpler substances.

Magnesium metal is added to nitrogen gas. 3 Mg + N 2  Mg 3 N 2 Synthesis. Excess chlorine gas is passed over hot iron filings. 3 Cl 2 + 2 Fe  2FeCl 3 Synthesis. The gases boron trifluoride and ammonia are mixed. BF 3 + NH 3  F 3 BNH 3 Synthesis(Lewis Acid-Base Reaction).

What is Stoichiometry?. Objectives: 6.0 Solve stoichiometric problems involving relationships among the number of particles, moles, and masses of reactants and products in a chemical reaction 6.3 Identifying the nomenclature of ionic compounds, binary compounds, and acids

Chemical Reactions. February 21, 2002. Evidence for Chemical Reactions. Color change Precipitation Gas production Changes in temperature Changes in properties. Chemical Equations. A shorter, easier way to showing chemical reactions using symbols instead of words

Ch. 8 – Chemical Reactions. III. Types of Chemical Reactions (p. 256 - 267). A. Combustion. the burning of any substance in O 2 to produce heat. A + O 2  B. CH 4 (g) + 2O 2 (g)  CO 2 (g) + 2H 2 O (g). A. Combustion. Products : contain oxygen hydrocarbons form CO 2 + H 2 O.

Redox: oxidation and reduction reactions made fun. Redox explains the chemistry behind batteries and electroplating precious metals onto strong base metals. It also explains how to break apart water into hydrogen and oxygen, and lots more. These 2 reactions are always paired and balanced.

Types of Chemical Reactions. Aim: What are the five general types of reactions?. 5 Types of Chemical Reactions. synthesis Decomposition Single Replacement Double Replacement Combustion. #1 - Synthesis Reactions. Combine = put together

There are six main types of reactions. Synthesis Decomposition Combustion Single Replacement (Single Displacement) Double Replacement (Double Replacement) Neutralization. Synthesis. A combination of two or more substances to form a larger substance. A + B  AB Examples:

Classification of Chemical Reactions. Notes. Composition (also called combination or synthesis). Two reactants combine to form one product A + B  AB Example: 3Na + P  Na 3 P Helpful hints

Final Exam Review Stations Units 4-7. 45 Questions in 80 minutes (TOTAL) 18 Questions = 40 points 32:00 timer. Station 1 (Bonding Unit 4). Which of the following chemical formulas is incorrect? BaOH 2 NH 4 Cl KNO 3 CaSO 4 Sr (C 2 H 3 O 2 ) 2. Station 1 (Bonding Unit 4).

Redox Reactions – Examples (1 – Synthesis) The following is one type of oxidation/ reduction reaction. Balance the equation. Indicate the species that are oxidized and reduced. Write the half reactions for each. Fe + O 2 ---> Fe 2 O 3.

Redox Net Ionics. Oxidation number on at least two elements must change. Types of Redox RXNS. RXNs: Single replacement, synthesis, and some decomposition. To predict products look at the reactants to see if there are oxidizing and reducing agents.

Warm-Up March 11, 2013. Write down the date and objective. Objective: SWBAT discern the differences between types of reactions by writing and performing skits. Complete the following warm-up: What type of reaction is taking place in the following examples (chemical or physical)? Paper rips

Orgo C licker Review. Which of the following is NOT an organic molecule?. Glycerol Lactose RNA CO 2 Amino acid. Glucose and fructose are both C 6 H 12 O 6 , they are considered. polysaccharides Isomers Amino acids Fatty acids.

Predicting products of hydrocarbon combustion, single replacement, and double replacement reactions. Chem -To-Go Lesson 22 Unit 5. Using Patterns to predict. COMBUSTION of hydrocarbon. Single replacement of metals. Single replacement of Halogens. Double replacement.

Chemical Reactions. Chapter 7.2 Notes. Chemical Change. A chemical change occurs when a substance reacts and forms one or more new substances. Signs of a chemical change include color change, temperature change, light produced, gas formed, precipitate formed. Reactions.

Water. How can water be physically changed? How can water be chemically changed?. Chemical Change. any change in which a new substance is formed with new physical properties. This involves breaking bonds and forming new ones with other elements

3. 2. 3. 3. 3. ___ Li + ___ AuCl 3  ___ LiCl + ___ Au. Mad Minute Review . 3. 2. 3. ___ Ca 3 P 2  ___ Ca + ___P. Name the types of reactions for the above reactions as synthesis, decomposition, single replacement, double replacement   1b. ____________________________

Notes: Energy and Chemical Reactions . Exothermic – Reaction in which heat energy is released. “ Exo ” means outside . Energy is released to the “outside.” Example: Burning – Substance combines with Oxygen to form heat, Light, CO2 or Water. (Combustion)

Unit 7. Chemical Reactions Balancing Chemical Equations Types of Reactions. Chemical Reactions. Remember – A chemical change occurs when substances react together and form NEW products. Examples of this include : rusting Combustion Tarnishing Fermentation oxidation
