Given the following equilibrium constants: Kb B(aq) + H2O(l) ⇌ HB+(aq) + OH−(aq) 1/Kw H+(aq) + OH−(aq) ⇌ H2O(l) What is the equi

<u>Answer:</u> The value of $K_c$ for the net reaction is $\frac{K_b}{K_w}$

<u>Explanation:</u>

The given chemical equations follows:

<u>Equation 1:</u> $B(aq.)+H_2O(l)\rightleftharpoons HB^+(aq.)+OH^-(aq.);K_b$

<u>Equation 2:</u> $H^+(aq.)+OH^-(aq.)\rightleftharpoons H_2O(l);\frac{1}{K_w}$

The net equation follows:

$B(aq.)+H^+(aq.)\rightleftharpoons HB^+(aq.);K_c$

As, the net reaction is the result of the addition of first equation and the second equation. So, the equilibrium constant for the net reaction will be the multiplication of first equilibrium constant and the second equilibrium constant.

The value of equilibrium constant for net reaction is:

$K_c=K_1\times K_2$

We are given:

$K_1=K_b$

$K_2=\frac{1}{K_w}$

Putting values in above equation, we get:

$K_c=K_b\times \frac{1}{K_w}=\frac{K_b}{K_w}$

Hence, the value of $K_c$ for the net reaction is $\frac{K_b}{K_w}$

What is the mass of 8.0 x 10^26 UF6 molecules?

gulaghasi [49]

First, find the number of moles of UF6
Avagadro's number = 6.023 x 10^23

Number of moles = 8.0 x 10^26 / Avagadro's number = 8.0 x 10^26 / 6.023 x 10^23 = 1.328 x 10³ moles

Molecular weight of UF6 = Molecular weight of U (238.02891) + Molecular weight of F6 (6 x 18.9984032) = 238.02891 + 113.9904192 = 352.0193292 g/mol

Therefore mass of 8.0 x 10^26 UF6 molecules = 352.0193292 g/mol x 1.328 x 10³ moles = 467.481669 x 10³ grams

Is C2H7 ionic or covalent? <br><br> what would you name NO4? <br><br> what would you name MgCl2?

Vlad [161]

C₂H₇ is a covalent compound

N0₄ will be name nitrogen(viii) oxide

MgCl₂ will be named magnesium chloride.

<h3>What are covalent compounds? </h3>

Covalent compounds are compounds which are formed when two electronegative atoms combine together by a sharing of electrons between them.

Covalent compound molecules are usually formed from a combination of non-metals.

The C₂H₇ is a covalent radical formed from the addition of a hydrogen ions to the covalent compound C₂H₆

<h3>What would you name NO₄?</h3>

The name given to a compound depends on the oxidation number of the component elements.

The oxidation number of oxygen is -2.

Since there are 4 atoms of oxygen, the total negative charge is -8.

Nitrogen will have to exist in the +8 state in order to give a neutral compounds.

Therefore, the name given to the compound will be nitrogen (viii) oxide.

<h3>What would you name MgCl₂? </h3>

Magnesium chloride, MgCl₂ is an ionic compound formed from the ionic bond between chlorine and magnesium.

Magnesium donates two electrons to two chlorine atoms to form magnesium chloride, MgCl₂.

The muscles on the run in transform chemical potential energy into_____

LekaFEV [45]

Mechanical Energy

Mechanism energy is the energy associated with the position and motion of an object. Therefore it is also the summation of the kinetic and potential energies of the object.

Explanation:

Mechanism energy is the energy associated with the position and motion of an object. Therefore it is also the summation of the kinetic and potential energies of the object.

In the muscles, to have movement, the chemical bonds in ATP is broken to enable the sliding action of the myosin and actin fibres of a sarcomere (the basic unit of muscle). This sliding action is responsible for contraction of muscle. The coordinated contractions and relaxations of sarcomeres on muscles result in movement which translates to mechanical energy.

This process is never 100% efficient with some energy lost as heat energy.
