What is the approximate value of the equilibrium constant, k n, for the neutralization of acetic acid withsodium hydroxide, show
NikAS [45]
You are given the neutralization of acetic acid with sodium hydroxide. Also, you are given the k for acetic acid, which is 1.8 x 10⁻⁵. You are asked to find the<span> approximate value of the equilibrium constant, kn, for the neutralization. We will have a reaction of both acetic acid and sodium hydroxide.

CH</span>₃COOH + NaOH → CH₃COONa + H₂O
which comes from
CH₃COOH → CH₃COO⁻ + H⁺
H⁺ + OH⁻ → H₂O<span>

</span>The k for water is always 1.0 x 10¹⁴. The Ksp for the reaction will be
<span>
Ksp = [</span>CH₃COOH][H₂O]
Ksp = (1.8 x 10⁻⁵)(1.0 x 10¹⁴)
<span>Ksp = 1.8 x 10</span>⁹

H2(g) + CO2(g) + 10 kcal H2O(g) + CO(g)
EleoNora [17]

<u>Answer:</u> The equilibrium constant for the given reaction is 0.8

<u>Explanation:</u>

Equilibrium constant is defined as the ratio of concentration of the products raised to the power its stoichiometric coefficients to the concentration of reactants raised to power its stoichiometric coefficient. It is represented as K_c

For the general equation:

aA+bB\rightleftharpoons cC+dD

The equilibrium constant is represented as:

K_c=\frac{[C]^c[D]^d}{[A]^a[B]^b}

For the given chemical equation:

H_2(g)+CO_2(g)+10 kcal\rightleftharpoons H_2O(g)+CO(g)

K_c for this equation is given by:

K_c=\frac{[H_2O][CO]}{[H_2][CO_2]}

Concentration at equilibrium of

H_2=2mol/L\\H_2O=4mol/L\\CO_2=5mol/L\\CO=4mol/L

Putting values in above equation, we get:

K_c=\frac{4\times 4}{2\times 5}\\K_c=0.8

Hence, the equilibrium constant for the given chemical reaction is 0.8

Which of the following chemical formulas show three molecules of a compound that has one
mr_godi [17]

The chemical formula : 3HgBr₂(Mercury(II) bromide)

<h3>Further explanation</h3>

Given

The chemical formulas of Mercury and Bromine

Required

The appropriate chemical formula

Solution

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

The number of molecules is determined by the coefficient in front of the compound

the number of atoms is determined by the subscript after the atom and the coefficient

Three molecules⇒ coefficient = 3

one atom of Mercury ⇒Hg

two atoms of Bromine ⇒ Br₂

The chemical formula : 3HgBr₂

Which describes colloids? Check all that apply.
nirvana33 [79]

Answer:

In chemistry, a colloid is a mixture in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance. ... Some colloids are translucent because of the Tyndall effect, which is the scattering of light by particles in the colloid.
