Al belongs to group III elements in periodic table so it forms Al3+ ion. check w the formula Al2O3:  2x(+3) from Al = +6 which equal to 3x(-2) from O. so its balanced.

Al ionizes from neutral to Al3+ and 3 e- to bond w O.

Given the chemical formula Al2O3  and every oxygen ion (combined with an aluminum ion) has a charge of -2, the total negative charge is -2x3 = -6.

As Al2O3 is neutral, the total positive charge must be 6.  The charge of each aluminum ion is 6/2 = 3.

An uncharged aluminum atom must lose 3 electrons so that it will bond with oxygen.

The individual dipole moments in ammonia (NH3) do not cancel each other
kozerog [31]

Answer:

                    The strongest force that exists between molecules of Ammonia is <em>Hydrogen Bonding</em>.

Explanation:

                    Hydrogen Bond Interactions are those interactions which are formed between a partial positive hydrogen atom bonded directly to most electronegative atoms (i.e. F, O and N) of one molecule interacts with the partial negative most electronegative atom of another molecule.

                    Hence, in ammonia the nitrogen atom being more electronegative element than Hydrogen will be having partial negative charge and making the hydrogen atom partial positive. Therefore, the attraction between these partials charges will be the main force of interaction between ammonia molecules.

                  Other than Hydrogen bonding interactions ammonia will also experience dipole-dipole attraction and London dispersion forces.

Pavlova-9 [17]

Answer: b. False

K+ ions move faster than the Na+ ions through the neuron membranes.

The concentration of Sodium ions outside the cell is very high. The concentration of Potassium ions inside the cells is very high. Leakage channels thus allow sodium ions to move inside the cells and pumps out the Potassium from the cells.
