Why is it necessary to add concentrated HCl, then water, rather than a solution of HCl to the eudiometer tube

Chemistry

The reaction between concentrated acid and water can release a lot of heat. If a little water is added to a larger amount of acid, the heat can cause the small amount of water to boil very rapidly which then spatters some acid. ... It is recommended that acid should be added to water and not water to acid.

Answer:

Chemical reactions takes place

Explanation:

Chemical energy stored in bonds of chemical compound are released when chemical reactions takes place.

Chemical energy is a form of potential energy that is found in chemical bonds.

  • When chemical reactions occur, bonds are broken and formed again.
  • The process of breaking and forming new bonds releases chemical energy.
  • In this manner most chemical reactions are often accompanied by energy changes
  • The energy changes is due to the formation of new bonds.

The vapor pressure of water at 25 •C is 23.8 mmHg. Write K for the vaporization of water in the unit of atm. What is Kc for the
r-ruslan [8.4K]

The degree of dissociation gives the amount of the substance that dissociated into the products. The value of Kc for water is 1.28 x 10⁻³.

<h3>What is equilibrium constant, Kc?</h3>

The equilibrium constant, Kc is the equilibrium concentration of the products over the reactants that are raised by the powers of their stoichiometry coefficient.

The reaction is shown as:

H₂​O(l) ⇋ H₂​O(g)

Kp = pressure of water = 0.03131579 atm

\rm Kp = Kc(RT)^{\Delta n}

Here Δ n = 1

Solving further,

Kp = Kc(RT)

0.03131579 = Kc(0.0821 × 298.15)

Kc =1.28 x 10⁻³

Therefore, Kc is 1.28 x 10⁻³.

Life Span. The life span of damselflies varies between species and within species depending on environmental factors. After one to three weeks, the eggs, laid in water, usually hatch, releasing the larvae or nymphs, but eggs laid in late summer may overwinter before hatching.
