1 Minimize the organic solid wastes (ie food) that are put down the kitchen drain. Follow with water to flush the pipes. 2  Do not put materials that cannot decompose down any drain.  Do not allow hair to go down the lavatory drain if possible â remove from the lavatory and dispose of in the trash.
The reason the periodic table is the shape that it is has to do with the electronic configurations of the elements. The periodic table is arranged so that all the elements in each period (row) have similar electronic configurations to the other elements in that period. That also often means that elements in the same group (column) show similar chemical reactivity. Electrons in atoms are arranged in different orbitals (named s, p, d, and âf).
To determine shape and polarity we have to look at the electron arrangement around the central atom; in this case that's the carbon atom, and the carbon atom has four groups of electrons, so it has a tetrahedral arrangement of electrons. Each of those four groups of electrons is a bond to a chlorine atom.There are no unbonded pairs of electrons, so the shape of the molecule is the same as the shape of the electron arrangement. It is a tetrahedral molecule.o determine shape and polarity we have to look at the electron arrangement around the central atom; in this case that's the carbon atom, and the carbon atom has four groups of electrons, so it has a tetrahedral arrangement of electrons.
