Abstraction The determination of the melting point is crucial for identifying an unknown substance. For this experiment, a melting point apparatus was used to measure the melting point. The melting point of the unknown sample #10 was found to be 111. 5 C. The melting points of two compounds, dibenzoyl ethylene and o-Toluic acid, were […]
To ensure safety and prevent any damage, I allowed the first test tube with substance c to cool down before storage. For the second test tube, I filled it with cold water and stirred it using a glass stirring rod. I then carefully heated the sample over a burner fuel wick, ensuring that the flame […]
Planning: * There are many ways in which to find out what ions are contained in different compounds. When substance is mixed to make solution, precipitation reactions and reactions with gas specifically are very useful to help us out with identifying which ions are contains in the substances. This test is for negative ions. * […]
Answer: the Impacts chemistry have on a society Is huge. Every single material that we come In contact with, In our dally Fife Is composed of chemicals there are negative and positive effects of chemistry but the negative effect Is mainly due to the Inability of a man to think carefully first of all lets […]
In 1750, Rudder Bishopric challenged the theory that atoms were “uncountable” by proposing that atoms could contain smaller parts, leading down to fundamental building blocks of matter that must be geometric points with no size. Today, many atomic physicists accept this modern idea. In the late 1700s, French chemist Antoine Lavoisier revolutionized chemistry by interpreting […]
Chemistry is very vital because it helps us to know the composition and changes of matter. Every single day of our life passes through chemistry in many ways. Human body works through the chemical reactions happening inside it. When we breathe, eat and sleep there’s still the presence of chemistry. The oxygen and foods we […]

The emotions that you feel are a result of chemical messengers, primarily neurotransmitters. Love, Jealousy, envy, infatuation and infidelity all share a basis in chemistry. Why Onions Make You Cry Marcelo Briton Folio They sit there, so harmless-looking on the kitchen counter. Yet as soon as you cut an onion, the tears begin to fall. […]
Properties of Gases Purpose: The purpose of this lab is to investigate some physical and chemical properties of gases and to use these properties to identify these gases when they are encountered. Hypothesis: This experiment was for observational purposes to learn about the physical and chemical properties of gases, no hypothesis was required In order […]
It Is Imperative that two main rules are always ollowed when conducting a qualitative analysis . The first rule is that the instructions must be followed exactly. The second rule is that a known positive test and a known negative test should always be performed for a comparative visual analysis. If these rules are broken, […]

Global environmental concern persists over acid rain, despite increased awareness of the planet’s unhealthy condition. Acid rain is defined as rainfall with pH values below 5.6. To fully understand acid rain, it is crucial to comprehend sulfuric acid production. This project aims to explore the process of producing sulfuric acid, its uses, and the environmental […]
Chemistry plays an important part in studying Biology. It answers some questions that Biology could not explain alone. Questions like: How does an organism convert foods for energy? How do plants use sunlight and water into all the things that cells needed to grow and reproduce? How does the basic unit of life passed through […]
Lab Report: Determination of a chemical formula: the empirical formula of Magnesium Oxide 1. Purpose: Determine the empirical formula of magnesium oxide from the percent composition (this can be found using the Analytical Method and the Synthesis Method) Introduction: In the late eighteenth century, combustion has been extensively studied. According to Steven and Susan Zumdahl, […]
A compound is a chemical substance composed of at least two elements with specific physical and chemical properties. It has a defined structure and cannot be separated by physical methods like boiling, freezing, sieving, or gravity thickening. When elements combine to form a compound, they lose their individual properties. Water (H2O) is an example of […]
I did this lab to find out the differences between chemical and physical changes. I also did this lab to learn the signs that would indicate the chemical reactions and physical changes. I needed to learn the odor change, color change, bubbles or gas, irreversible, temperature changes and finger prints. By the end of the […]
