Znse is a semiconductor with the zinc blende structure such that the zinc ions at the corners of the cubic lattice touch the selenium ions located at tetrahedral sites (1/4,1/4,1/4). the unit cell has 4 zn ions and 4 se ions effectively inside the cube. calculate the density of znse given the following data: the ionic radius of zn=0.083 nm and se =0.191 nm; the atomic weight of zn=65.38 amu and the atomic weight of se=78.96
answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
