A sample of 7.34 g of solid calcium hydroxide is added to 34.5 mL of 0.380 M Aqueous hydrochloric acid.Write the balanced chemic
1 answer:
Answer:
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.
The balanced chemical equation is:

Explanation:
a) Weak acid is defined as the acid which does not completely dissociates when dissolved in water. They have high pH. These releases ions in their aqueous states.
The equation for the dissociation of acid is given by:
b) According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
For the given chemical equation:
is loosing a proton, thus it is considered as an acid and after losing a proton, it forms
which is a conjugate base.
And, is gaining a proton, thus it is considered as a base and after gaining a proton, it forms
which is a conjugate acid.
c) Neutralization reaction is a reaction in which an acid reacts with base to produce salt and water.
d) The chemical equation for dissociation of in water.
e) The chemical equation for the reaction of and
