How do you calculate percent Half Life? As you can see from this table, the amount of reactant left after n half-lives of a first-order reaction is (1/2)n times the initial concentration….Half-Lives and Radioactive Decay Kinetics. Number of Half-Lives Percentage of Reactant Remaining 1 100%2=50% 12(100%)=50% 2 50%2=25% 12(12)(100%)=25% 3 25%2=12.5% 12(12)(12)(100%)=12.5% n 100%2n (12)n(100%)=(12)n% […]
What are the similarities and differences between prokaryotic and eukaryotic cells?
What are the similarities and differences between prokaryotic and eukaryotic cells? Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow […]

Which of these is a consequence of speeding less wear on brakes?
Why do electrons move in magnetic field?
Why do electrons move in magnetic field? Cyclonic movements Free-electron Landau states are a form of quantized state adopted by electrons moving through a magnetic field. All charged particles interact with electromagnetic fields via the Lorentz force. This interaction causes electrons in a magnetic field to move in a corkscrew pattern. Are electrons attracted to […]
How does my body know how do you carry out the essential functions of life?
How does my body know how do you carry out the essential functions of life? Systems of specialized cells within organisms help them perform the essential functions of life, which involve chemical reactions that take place between different types of molecules, such as water, proteins, carbohydrates, lipids, and nucleic acids. All cells contain genetic information […]

Which are examples of water absorbing energy?
Which are examples of water absorbing energy? When water absorbs enough heat, it becomes a gas (water vapor). This process is called evaporation. Water vapor (steam) mixes with the air and seems to disappear. A simple example is water boiling in a teapot and escaping into the air. What happens when the kinetic energy of […]
