Magnesium Floride (MgF2)
no yes it is you have just spelt it wrong its Fluorine (F)
yes they will
Mid water
Well hopfully it will purify water and might stop us getting our teeth getting brown stains.
Benzene, chlorine, floride and nitrates and pesticides
Carbon tetrachloride, CCl4, is non-polar- with a zero dipole moment. The C-Cl bonds are polar because of the electronegativity difference between C an Cl however because of the tetrahedral symmetry of the molecule the bond dipoles cancel.In water, H2O, a molecule with a bent shape the bond dipoles and lone pair dipoles do not cancel so the molecule has a net dipole moment.
Many tetras prefer soft and acidic water.
fresh, its a tetra if its this one
configuration of water molecule
Unequal sharing of electrons in a water molecule causes the molecule to be polar.
Water is a polar molecule.
