Which of the following is a correct balanced equation for the neutralization reaction that occurs between al(oh)3 and hcl (aq)? a. al(oh)3 + 3 hcl (aq) ô alcl3 + h+ + oh b. al3+ + oh- + h+ + cl- ô alcl3 + h2o c. al(oh)3 + hcl (aq) ô alcl3 + h2o d. al(oh)3 + 3 hcl (aq) ô alcl3 + 3 h2o

Neutralization reaction takes place between an acid and a base to form salt and water.

In the given reaction the acid is hydrochloric acid HCl and the base is aluminum hydroxide (Al(OH)).

The correct balanced equation for the neutralization reaction that occurs between aluminum hydroxide and hydrochloric acid can be represented as:

Al(OH)can give 3 hydroxide, ions which can neutralize the 3 ion produced by 3 HCl molecules giving 3 mole of water and the salt aluminum chloride, AlCl.

Therefore the correct option will be.

D. Al(OH)3 + 3 HCl (aq) --> AlCl3(aq) + 3 H2O(l)

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
