Natural resources are useful materials that we get from the Earth such as coil, oil, water, and natural gas. They occur naturally, which means that humans did not make them. Humans use natural resources to form new substances that can be beneficial to us, such as synthetic materials. Synthetic materials are formed when humans deliberately mix substances together for the express purpose of creating new materials with desirable properties and are a big part of our day to day lives. Most synthetic materials are the result of chemical reactions during which the atomic structures of the original substances are rearranged to form the new material. You are pondering synthetic vs. natural products as you follow your mom through the grocery store. Which list contains ONLY synthetic materials you might find? A) jute, paper, bananas, almonds B) plastic bag, grapes, aspirin, chocolate bar C) potatoes, almond milk, multivitamins, styrofoam cups sugar free ice cream, paper plates, chocolate covered raisins, styrofoam cups, bottled water D) 53°F a

Even though cement and bread are not substances, they can help you to understand these concepts: Whatever you do to volume affects mass the same way. Whatever you do to mass affects volume the same way. If you have half as much of a material, you would expect the volume of the material to also be half as much. If you have twice as much of the material, you would expect its volume to also be twice as much. Substances, which you know are always the same throughout, will follow this rule. This relationship between mass and volume will stay the same for any substance, no matter how much of that substance you can sample and measure in the classroom. Why is this principle about the relationship between mass and volume always true of substances, but not always true of mixtures?
Make a network using the following concepts: substance, compound substance, simple substance, decomposition, chemical change. Do not forget to place on each arrow the relationship that connects the two concepts linked by it.
CHEMISTRY Calculating Density Density is the compactness of matter. Density describes the quantity of matter (mass) per unit of volume (3-dimensional space). Density is calculated as the mass of the matter divided by volume. The symbol for density is Greek letter rho (p). The units for mass are in grams (g) and the units for volume is cubic centimeter (cm³). It should be noted that 1 cm³ is equal to 1 ml of volume. 1 cm³= 1 ml. The units for density are g/cm³. Part 1 Determine the density of the new liquid materials created in the Secret Density Research Laboratory. Type the value (no units) of the density into the boxes in the density column. Report density to the 2nd number after the decimal. Use a zero to the lef of the decimal for values less than 1.00. Examples: 2.35, 0.75, 1.90 Material name Harrisonite Waltonium Kellese Wheelernone Osborneum Popebrillium Mass (g) 430 590 260 m P=V 620 380 510 Volume (cm³) 537 454 236 364 633 340 Density (g/cm³) SAMSUNG
You are a researcher in a geochemistry laboratory. A colleague brought to you a new mineral that you have never seen before. You need to identify all of the elements and their quantities in this mineral. You turn the mineral into a powder and put the mineral into multiple scientific machines to determine what it is made of. Your sample contained the following elements and amounts. • 160 grams of oxygen 120 grams of silicon • • 80 grams of aluminum . 16 grams of magnesium 32 grams of calcium. . 4 grams of uranium. Determine the mass percent of the different components in your soil sample. • 29. Oxygen 30. Silicon 31. Aluminum 32. Magnesium 33. Calcium 34. Uranium
Your breakfast this morning was so nutritious! You had two eggs, a slice of toast and some orange juice. You were lucky, though... your mom noticed some smoke coming from the toaster and took your toast out before it burned. Thanks to her, your toast was a perfectly crunchy and light-brown in color: During this process, did the bread undergo a physical change or a chemical change? What evidence from the story or the image proves that you are correct?
Complete each of the following sentences by placing the word chemical or physical in the blank: The crushing of rocks to make gravel is a procedure. The burning of wood is a process. Converting water into hydrogen and oxygen is a procedure. The freezing of a liquid is a process.

O A pure substance can be varied by changing the proportion of pure substances making it up A mixture can be separated into 2 or more substances by physical or mechanical means A pure substance had properties that are constant, no matter where you find it A pure substance has constant chemical composition A mixture's composition can be varied by changing the proportion of pure substances making it up
Explain your rationale for using the summative assessment (below) from the lesson plan on mixing substances in a 5th-grade classroom based on the below standard and learning objective, including how you will use student outcomes to inform future instructional decisions. Summative Assessment Summative: Components of the Lab Report Purpose: The student should clearly state the purpose of the experiment, which is to determine whether the mixing of two or more substances results in new substances. Procedure: The student should describe the steps they took to conduct the experiment. This includes the substances they chose to mix and the safety equipment they used. Observations: The student should record any observable changes that occurred when the substances were mixed. This could include a color change, the formation of a precipitate, or a change in temperature. Conclusion: The student should state whether a new substance was formed based on their observations. They should also…

4. Gasoline can be reasonably approximated as C9H20 with a density of 0.718 g/mL. Diesel can be reasonable approximated as C14H30 with a density of 0.763 g/mL. (Both gasoline and diesel are complicated mixtures. These formulas are something like weighted averages of the formulas of the different components, where the weighting is based on various quantifiable behaviors. That is, using these artificial formulas for gasoline and diesel allows one to calculate average properties that match what petroleum engineers might measure.) The enthalpy change from burning one mole of gasoline is -6160 kJ. The enthalpy change from burning one mole of diesel is -7940 kJ. Determine which fuel generates the biggest enthalpy change per gram burned, and which generates the biggest enthalpy change per mL burned.
