The products

Chemistry
1 answer:
alexandr1967 [171]3 years ago
6 0

Answer:

The products  of self-ionization of water are OH⁻ and H⁺.

Explanation:

  • The water is self ionized according to the equation:

<em>H₂O → OH⁻ + H⁺. </em>

<em></em>

The ionic product for water (Kw) = [OH⁻][H⁺] = 10⁻¹⁴.

Kw is also called "self-ionization constant" or "auto-ionization constant".

This gas can be formed if a hydrogen bomb is detonated.
Levart [38]

Answer:

Helium.

Explanation:

Hydrogen in the bomb is used in the process of detonation. A stream of tritium, an isotope of hydrogen is released and this fissionable material is very unstable thus it turns during the detonation to helium 3. This triggers a series of reactions that produce large amounts of heat to the surrounding environment causing destruction.

Given a solution with a hydroxide ion concentration, oh=3.73×10^-5,what is the ph
Stells [14]

Answer:

  • <em><u>pH </u></em><u>= 9.73</u>

<u></u>

Explanation:

<em>pOH</em> is the negative logarithm of the molar <em>concentration</em> of<em> hydroxide ions </em>and pH is the negative logarithm of the concentration of hydronium ions.

The mathematical expression to determine pOH is:

         pOH=-\log [OH^-]

Where [OH⁻] means the molar concentration of hydroxide ions.

Substituting:

        pOH=-\log {(3.73\times 10^{-5})

       pOH=4.43

<em>pH </em>and <em>pOH</em> are related by the equation:

           pH+pOH=14

From which:

           pH=14-pOH\\\\pH=14 - 4.43\\\\pH=9.57\leftarrow answer

Consider the following reaction: CHCl3(g) + Cl2(g) → CCl4(g) + HCl(g) The initial rate of the reaction is measured at several di
Ira Lisetskai [31]

Answer : The correct rate law for the reaction is,

\text{Rate}=k[CHCl_3][Cl_2]^{1/2}

Explanation :

Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.

For the given chemical equation:

CHCl_3(g)+Cl_2(g)\rightarrow CCl_2(g)+HCl(g)

Rate law expression for the reaction:

\text{Rate}=k[CHCl_3]^a[Cl_2]^b

where,

a = order with respect to CHCl_3

b = order with respect to Cl_2

Expression for rate law for first observation:

0.0035=k(0.010)^a(0.010)^b ....(1)

Expression for rate law for second observation:

0.0069=k(0.020)^a(0.010)^b ....(2)

Expression for rate law for third observation:

0.0098=k(0.020)^a(0.020)^b ....(3)

Expression for rate law for fourth observation:

0.027=k(0.040)^a(0.040)^b ....(4)

Dividing 1 from 2, we get:

\frac{0.0069}{0.0035}=\frac{k(0.020)^a(0.010)^b}{k(0.010)^a(0.010)^b}\\\\2=2^a\\a=1

Dividing 2 from 3, we get:

\frac{0.0098}{0.0069}=\frac{k(0.020)^a(0.020)^b}{k(0.020)^a(0.010)^b}\\\\1.42=2^b\\b=\frac{1}{2}

Calculation used :

1.42=2^b\\\log (1.42)=b\log 2\\\log (\frac{1.42}{2})=b\\b=0.5=\frac{1}{2}

Thus, the rate law becomes:

\text{Rate}=k[CHCl_3]^1[Cl_2]^{1/2}
