<span>Of SiF4 and SiBr4, the atom SiF4 is more polar. This is because the cation of both molecules are Silicon, but the anions of each are different. In SiF4, the anion is Fluorine, which is more electronegative than the Bromine in SiBr4, which creates a larger dipole, which results in a more polar molecule.</span>
<span>If we put a Rhoeo leaf in plain water, the water concentration of the leaf cells will be higher than that of the plain water. The aim is to balance water concentration on the inside and outside of the organism. So, the water will exit the leaf cells, which will consequently shrink in size. The most of the cells will shrink in size, causing the leaf to shrink, too.</span>
