Fluorine needs one electron to fill its orbital shell. It needs 8 valence electrons
Membranes are barriers and “gatekeepers”, they only let certain molecules pass through them.
they also transport nutrients to the cell
<span>In the Bohr model electrons in atoms can occupy allowed orbits where they do not emit energy. Exchange of energy with the surrounding environment occurs only when an electron "jumps" from an orbit to another. Hope this answers the question. Have a nice day.</span>
3/8 NA = 3/8 x 6.023 x 10^23 molecules of h2o
so, we can easily conclude that 1mole of CH4 gives 2mole of H2o
