All of the following happen when an acid reacts completely with a base EXCEPT: the pH moves to 0 on the pH scale the pH is equal to 7 the solution mixture is neutralized salt and water form

the pH moves to 0 on the pH scale

Explanation:

A base is defined as a substance which donates hydroxide ions when dissolved in water and an acid is defined as a substance which donates hydrogen ions in water.

Neutralisation reaction  is defined as the chemical reaction in which an acid reacts with a base to produce a salt and water molecule. The ions from acid are neutralised by ions from base.

Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH of 7.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
