experiment is to investigate the chemical and physical properties of pure chemical substances. A property of a substance is some distinguishing characteristic. Some of the most common physical properties are color‚ odor‚ hardness‚ density‚ melting point‚ boiling point‚ and solubility in various solvents. For all of these properties‚ no chemical change takes place. Chemical properties describe the tendencies of a substance to undergo chemical change. For example‚ copper gets heated in a flame‚ the surface

Physical properties can be seen‚ touched‚ or even measured without the identity of the substance changing. The identity of the substance can be its shape or color. Three physical forms of a substance are solid‚ liquid‚ and gas. Water for example can transform into all three physical forms without its identity changing. The characteristic of water as a shape can be used as an example of a physical property. Water can be frozen into ice‚ vaporized‚ or liquidized. The shape of water as a solid is

Mystery mixture has a variety of sizes from the crystals with powder over it. Also from the powdery substance in it. There is no exact size for the mystery mixture. The claim the scientists have is similar to the mystery mixture. It is similar to the claim because the scientists found that there is an exact size‚ but there also isn’t. This is because they

Common issues include loss of focus and irritability are caused by withdraw from most abused substances. Her lack of sleep is also a common symptom when adequate amounts of a needed substance are not ingested. This is considered withdrawal. To meet these criteria‚ Marla must have been using the substance for an extended period. Any depressants tend to

Dependency or Substance Dependency and Substance Abuse in Adolescents; specifically the development‚ progression and biopsychosocial of dependency and abuse in the adolescent population. The definition of epidemiology and diagnosis will be addressed. Lastly three treatment options including the range of severity will be provided. There is difference between substance abuse and substance dependence. The distinction between the two is characterized by the role they play in a person’s life. Substance dependence

Addiction usually refers to a more severe substance use disorder‚ “that is characterized by having more symptoms‚ tolerance‚ and withdrawal by using more of the substance than intended” (Kring & Johnson‚ 2014‚ p.286).

In experiment #1‚ we were able to detect physical properties of the aluminum and copper sulfate simply by looking at the substances. We then combined the two substances to see if they would create a chemical reaction and test the chemical properties. After being combined‚ bubbles and gas were created and the color of the substance changed‚ validating that
