Answer:
Sodium-Potassium Pumps
Explanation:
Sodium-Potassium Pumps written as Na-K Pumps are ion channels found in the cell membrane of nerve cells. These pumps are responsible for maintaining the different ion concentrations across the membrane and help in polarization and depolarization of the membrane by influencing membrane potential. During ion exchange these pumps transfer three sodium ions from inside to outside of the cell and two potassium ions from outside to inside of the cell. In this way they maintain the ion concentration gradient across membrane.
Answer:
n is the principal quantum number, it specifies the energy and average distance from the nucleus
l is the orbital quantum number, it specifies the subshell/orbital shape
ml is the magnetic quantum number and specifies the orbital orientation
Explanation:
The Schrödinger wave equation is solved for the hydrogen atom to yield three sets of quantum numbers.
The principal quantum number corresponds to the energy level in the Bohr model and also shows the average distance of the electron from the nucleus.
The orbital quantum number reveals the subshell where an electron is found as well as the shape of the orbital. E.g p-orbitals are dumbbell shaped.
The magnetic quantum number shows the orientation of an orbital in space. Its values range from -l to +l
Answer:
A precipitate forms; the colour changes.
Step-by-step explanation:
The formation of a precipitate a colour change are always signs that a chemical reaction has occurred.
A, B, C, and D are <em>wrong.</em> They are signs of a reaction, but you did not observe them here.
