Firstly (and most importantly) the actual chemical makeup of the compounds in terms of the specific elements involved, and those elements respective properties. Secondly the temperature, pressure, etc. at which a substance is at will affect the properties of the substance. Thirdly what other chemical compounds are effecting the substance, obviously different substances will react differently depending on what are reactants are present.
Three chemical properties are reactivity, flammability, and oxidation state.
Density, melting point, and boiling point are three physical properties that can help identify a substance. These properties are inherent to the substance and can be used to distinguish it from other substances.
Density, melting point, and boiling point are three examples of intensive physical properties. These properties do not depend on the amount of substance present and are useful for identifying and characterizing materials.
Examples: density, hardness, boiling point, refractive index.
Reactivity - how a substance interacts with other substances to form new compounds. Flammability - the ability of a substance to ignite and burn in the presence of oxygen. Acidity/Basicity - the pH level of a substance which determines if it is acidic or alkaline.
The three main chemicals in cigarette smoke are nicotine, tar, and carbon monoxide. These chemicals are known to be harmful to health and are associated with various diseases such as cancer, respiratory issues, and heart disease.
A substance can take on three physical states: Solid, liquid, or gas. The main physical changes from a thermodynamic standpoint are the amount of entropy(disorder) of the molecules of the substance. Density, temperature, volume are also characteristically different at each physical state and can be used to manipulate compounds between the three.
Reactivity: how a substance reacts with other substances to form new products Flammability: the ability of a substance to ignite and burn in the presence of oxygen Toxicity: the degree to which a substance can cause harm to living organisms when exposed to it
The chemical analysis show that the chemical composition of the molecule is the same.
Which brain imaging method uses magnetic properties of different atoms to take sharp, three-dimensional images of the brain.
All types of matter have the mass and volume.
The three different bottles likely contain samples of iron nail treated with different substances or under different conditions to demonstrate different properties of iron. This allows students to observe how iron reacts under varying circumstances or to test hypotheses about its properties.
