State the uses of Zinc sulphide
Zinc sulphide has a lattice constant of 0.596nm . The sulfide ions are quite big (atomic radius 184 pm) relative to the size of the zinc ions (74 pm). In the diamond structure sulphide ion (shown in grey) occupies the FCC lattice points with the Zinc ions(shown in red) is the other atom of the basis. When compared to diamond saphalerite structure is more soft. Therefore we can see that the strength of the tetrahedral bond verifies the hardness of the material.
Mass of the system is same. since, p=mv momentum remains same
sir please tell me about it
Discharging: The cell is connected across some load during discharging. As the direction of current by the cell is reversed during discharging the negative ions go in the directio
