How did you separate the components of salt water solution?
How did you separate the components of salt water solution? For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates. It is then cooled and condensed into a separate container. What technique […]

What are the 2 types of active transport?
What are the 2 types of active transport? Active transport requires cellular energy to achieve this movement. There are two types of active transport: primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient. Is facilitated diffusion an example of passive transport? Facilitated diffusion is a type of […]

What does conductivity depend on?
What does conductivity depend on? What does conductivity depend on? It depends on the concentration, mobility, the valence state of the ionized species in a solution, and the temperature at which a measurement is taken. The higher the concentration of the ions in water, the higher the conductivity. How does thermal conductivity depend on density? […]
What does the atomic mass tell you?
What does the atomic mass tell you? The atomic mass tells us the weight of protons and neutrons. How do you know how many electrons there are surrounding the nucleus of a particular atom? Why isn’t the atomic mass always a whole number? Atomic mass is never an integer number for several reasons: The atomic […]
How do we know the nucleus is positive?
How do we know the nucleus is positive? Rutherford deduced that the atomic nucleus was positively charged because the alpha particles that he fired at the metal foils were positively charged, and like charges repel. In Rutherford’s experiments most of the alpha particles passed straight through the foil without being deflected. Is a nucleus positive? […]
