Is Calcium An Element Compound Or Mixture – The elements and compounds are pure. False 2. Mixtures and compounds are pure. True Mixtures can be separated by physical means. False Elements can be broken down into simpler substances. False 5. Salt water is a compound.

Chapter 9 Today’s Goal: I can differentiate the arrangement of particles between elements, compounds and mixtures. I can identify the different parts of a solution. I can differentiate between heterogeneous and homogeneous mixtures.

Is Calcium An Element Compound Or Mixture

Homogeneous—a mixture of all the same (Example: A solution like lemonade) Heterogeneous—a mixture in which the particles remain physically separated (Example: Salad, Bag of M&Ms)

22 On your lab table… Look at each diagram and identify it as one of the following: 1) Element 2) Compound 3) Mixture—It can be a mixture of elements, a mixture of compounds, or a mixture of compounds and elements.

Hydrogen atoms are attracted to a greater extent than oxygen atoms. Hydrogen atoms are shown in various sizes There is one less hydrogen atom There is one more oxygen atom

24 Let’s review… 2. When sodium, a soft metal, combines with chlorine, a poisonous gas, salt is formed. Which statement is true about this combination? Sodium and chlorine physically combine to form a new substance that retains the properties of the original substance. Sodium and chlorine combine chemically to form new substances with new properties. Salt retains some, but not all, of the physical properties of sodium and chlorine. Salt can easily be separated back into sodium and chlorine.

Elements are the simplest forms of matter that cannot be broken down chemically. The names of the elements are listed in Table S. Compounds consist of two or more elements chemically combined in a fixed ratio. To differentiate them, use Table S or determine whether the substance can be described further.

Homogeneous: a uniform mixture also known as a solution. You can’t see the parts. Sometimes it gets the symbol (aq) for aqueous which means soluble in water. Heterogeneous: non-uniform mixture. You can see the parts.

Bell Work! Identify The Following As An Element, Compound, Or Mixture.

10 Rule of thumb: If a symbol is given with one capital letter or can be used to name a species, then it is an element. If two or more combined symbols, with two more capital letters are given or can be used to name a species, then it is a compound. All elements and compounds are homogeneous. If no chemical formula is given or can be found, then it does not have a fixed ratio and must be a mixture. These species can be homogeneous or heterogeneous.

14 Separating Mixtures There are many ways to separate a mixture. If it is heterogeneous, many can just sort it by hand. Otherwise, you can use: Pouring: The least accurate way to separate; You can pour the top layer of liquid from the bottom layer. (You’ve probably done this at a beach with a mixture of water and sand.)

15 Separating Mixtures 2. Filtering: To separate solids from liquids, filter them using a funnel and filter paper. The solid remains at the top, the liquid flows through it. (What happens if a solid dissolves completely in a liquid?)

Separating Distillation Mixtures: When two or more liquids are mixed homogeneously, you can boil each liquid separately using the following equipment: This is how many water bottling companies clean their water.

17 Separation of Mixtures 4. Chromatography: Mixtures can be dissolved and a small sample can be placed on filter paper. The filter paper will be placed in a wet container, and the sample will rise to the top, separating each component. This method is usually used to determine whether a sample is pure or not. It is not used to separate samples completely.

Classify objects into solid, liquid or gas. Identify phase changes and whether they require or release heat. Label and explain the phase change diagram.

27 Pressure Gases exert pressure on surrounding substances as they continually move and collide with other surfaces. Only in a vacuum, where there are no molecules, is there no pressure. Gas pressure can be measured in atmospheres or kilopascals, according to reference table A.

Which has the highest melting point? Which IMF is the weakest? Which has the lowest boiling point? Which IMF is the strongest? Which has a definite shape? Which has the exact volume?

29 What is steam? Vapor is the gaseous form of a substance that is usually liquid or solid at room temperature.

Endothermic reactions require you to introduce heat. Exothermic reactions require you to emit heat; heat comes out.

31 Phase Changes Identify phase changes and whether they are endothermic or exothermic: Evaporation Condensation Melting Freezing Sublimation Deposition Liquid to gas endothermic Gas to liquid exothermic Solid to liquid endothermic Liquid to solid exothermic Solid to gas endothermic gas to solid exothermic

Melting Point Boiling Point Freezing Point MP and FP are the same temperature for pure substances because they use the same phase!

Ws Classification Of Matter Key

33 Thermochemistry The science that studies energy changes that occur in chemical reactions. Kinetic Energy refers to the energy of motion. (Temperature) Potential Energy refers to stored energy.

What Are The Most Common Elements On The Earth’s Crust?

40 Changes in the Lab Physical Changes require that chemicals do not change composition. (Cracking, grinding, etc.) Chemical Changes require the chemical substance to change into a new substance. (Burn, react, etc.)

42 Observations Observations are carried out in various ways. Qualitative: appearance or behavior: not measured Quantitative: mathematical description. and Extensive: depending on the amount of material. Intensive: depends on the type of material
