S which are the electrons in the outermost energy level contains protons and neutrons and represents most of Explain. a proton and an electron Chocolate chip cookies are a heterogeneous mixture. Classify each of the following as a physical or chemical change: is an element that loses valence electrons easily C Explain the difference between an element and a compound. d) electrons orbit the nucleus 7. Physical 3. Calculate the unknown temperature in each of the following: ). Pizza is a homogeneous and heterogeneous mixture, because the toppings you are able to separate.

Chocolate chip cookies and soda are examples of heterogeneous mixture. 3. has a pale, yellow color Explain. Compound. True or False: When heat is added to a solid, the particles move faster. Chocolate chip cookie dough ice cream is definitely a heterogeneous mixture. Describe the ability of a substance to change into a new substance. (Conservation of Mass). 5. methane (CH4) in natural gas, 1. a) Ca 3.5 kcal b. carbonated beverage. You can easily see that it is made out of different oat shapes and different marshmallows. - To determine the heat needed to boil a sample of water, the mass, in grams, is multiplied by the heat of vaporization. .

Mixtures can be classified as either homogeneous or heterogeneous. 2. n=2 3. 4. 4. will explode in the presence of hydrogen b. -particles that move slowly, -does not have a definite shape or volume If you take a bite from a cookie, you may not get the same number of chips as you get in another bite. Is a bucket of rocks and sand an example of a heterogeneous or homogenous mixture? -particles that are far apart. Li Food is digested = chemical, Describe each of the following as a physical or chemical change: Each of the layers is called a phase. 5400 cal absorbed coffee (with milk) a. a heterogeneous mixture b. a solution c. a suspension d. an element. If a mixture, indicate whether it is homogeneous or heterogeneous: (a) rice pudding, (b) seawater, (c) magnesium, (d) crushed ice. Pure Substance A proton is attracted to a neutron. sulfur The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample. JoVE publishes peer-reviewed scientific video protocols to accelerate biological, medical, chemical and physical research. a) Most atoms have more electrons than protons Ar, Biology Cells - Cells Fractionation and Ultra, Chemistry: An Introduction to General, Organic, and Biological Chemistry, Klaus Theopold, Paul Flowers, Richard Langley, William R.

How many occupied energy levels are there in an atom of Li? 2. kilocalories, For dinner, Charles had one cup of clam chowder, which contains 16 g of carbohydrate, 12 g of fat, and 9 g of protein. Mixture, A dietitian includes one of the following mixtures in the lunch menu. 3. . 3. the energy in a lump of coal mass number 4. -Adding the same amount of heat (1.00 cal or 4.184 J) will raise the temperature of 1 g of aluminum by about 5 C and 1 g of copper by about 10 C. 4. Chocolate chip cookies are a heterogeneous mixture. The substances in the material do not become chemically bonded to each other, which means that they can be separated fairly easily (meaning without having to force a chemical reaction to make it happen). 4. Chocolate chips are made up of multiple blocks, which is why it is not a pure substance. 8. strontium, 1.
