Which of the following are weak electrolytes in aqueous solutions? Select ALL that apply.

Mandarinka [93]

Answer:

Weak electrolytes are

HgCl2 and NH₃

Explanation:

Electrolytes are compounds that conduct electricity while in molten or aqueous form.
Electrolytes may therefore be decomposed by passing electric current through them.

They may be either strong or weak electrolytes.

Strong electrolytes are those that ionize completely to form mobile ions while weak electrolytes ionize partially to generate ions.

Examples of weak electrolytes are HgCl2, NH₃
Examples of strong electrolytes are LiOH, HClO₄, and HI.

b)Elemental boron (as a gas) is produced in one industrial process by heating diboron trioxide with magnesium metal, also produc

dlinn [17]

<u>Answer:</u> The unbalanced chemical equation is written below.

<u>Explanation:</u>

Unbalanced chemical equation does not follow law of conservation of mass.

In an unbalanced chemical equation, total number of individual atoms on the reactant side will not be equal to the total number of individual atoms on the product side.

The chemical equation for the reaction of diboron trioxide and magnesium metal follows:

$B_2O_3(s)+Mg(s)\rightarrow B(g)+MgO(s)$

Hence, the unbalanced chemical equation is written above.

I think that it is D because the higher the molecular mass, the higher it's boiling point. I hope that helped:) Bye!

The yttrium- nuclide radioactively decays by electron capture. Write a balanced nuclear chemical equation that describes this pr

evablogger [386]

Answer:

See explanation and image attached

Explanation:

Yttrium has many isotopes, the lowest mass number of Yttrium is 89Y.

Recall that electron capture converts an electron into a proton and then into a neutron with a consequent emission of a neutrino (v).

In electron capture, the mass number of the daughter nucleus remains the same as that of the parent nucleus while the atomic number of the daughter nucleus is less than that of the parent by one unit.

An adult mosquitoes lifespan is about 16 days how many minutes is that

AVprozaik [17]

The answer is 23, 040 minutes. To solve this you can start by changing days in to hours. We know that there are 24 hours in a day. To find how many hours are in 16 days you multiply 24 by 16 which is 384. Next you must find out how many minutes are in 384 hours. we know there are 60 minutes per hour. To find how many minutes are in 384 hours, you multiply 384 by 60. To this you get 23, 040 which is your answer.
