According to the Arrhenius an acid and base react they form water and salt.

Explanation:

Neutralization reaction:

When an acid and base react they form water and salt.The reaction is called neutralization reaction.

According to the Arrhenius an acid is the substance which increase the H⁺ concentration, while base is the substance which increase the OH⁻ concentration.

General equation:

HX + BOH    →    BX   +  H₂O

From given reaction equations only option C is correct because only this reaction gives salt and water.

For example,

Chemical equation:

Ca(OH)₂ + H₂SO₄    →  CaSO₄ + 2H₂O

Calcium hydroxide is acting as a base. Sulfuric acid is an acid. Both these reactants react to form salt which is calcium sulfate and water.

Calcium hydroxide dissociate to gives Ca²⁺ ion and OH⁻ while H₂SO₄ dissociate to gives H⁺ and SO₄²⁻.  Ca²⁺  and SO₄²⁻ react to form salt CaSO₄  while OH⁻ and H⁺ form water.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
