Give three examples of heterogeneous mixtures and three examples of solutions that you might use in daily life. reaction. 8. metal, Give the symbol of the element described by each of the following: 5. is also a pure substance, but it consists of atoms of two or more elements always chemically combined in the same proportion. Changing either the elements that are present or their ratio changes the identity of the compound and, therefore, itsproperties. 37.0C=F <>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> 4. kilojoules to condense 175 g of steam, 1. The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample. All rights reserved. 155C to F 7. tin Furthermore, thephysical properties, such as color, shine, density, and melting point, of a pure substance must be consistent throughout the entire sample. Soda is considered a heterogeneous mixture. What does it mean to say that a solution is a homogeneous mixture? 4. Since two elements are present, this is a compound (sodium chloride, which is more commonly-known as "table salt.") Is Chocolate A Pure Substance?

Give three examples of homogeneous and heterogeneous mixtures, respectively. Cl Condensation, Using the values for the heat of fusion, specific heat of water, and/or heat of vaporization, calculate the amount of heat energy in each of the following: N What is this temperature in degrees Fahrenheit? If you took one bite of a cookie, the bite should be the same as all the rest of the bites of the cookies. 1. representative elements involved in These seemingly-mismatched elemental symbols actually correspond to a Greek or Latin word that can be used to describe the element. 6. Boiling Point: 100 degrees Celsius. How do mixtures differ from pure substances. What are the phases of a heterogeneous mixture? In F, normal body temperature is 98.6. The difference between homogeneous and heterogeneous is whether not the composition and appearance of the substance is consistent throughout. Explain. 46 C. 3. What is a heterogeneous mixture? Ca=calcium 3780 J, 904 cal 1. Wet clothes dry on a clothesline. Boiling a) Most atoms have more electrons than protons Some problems require a combination of steps that include a temperature change as well as a change of state, how would you calculate to get an answer?
