Which of the following best explains why electrolyte solutions conduct electricity?
skelet666 [1.2K]
<span>Answer: option C. the presence of free-flowing ions.
</span><span />

<span>Explanation:


Ionic compounds dissociate in water forming solutions with free ions. The solution conducts electricity and is named electrolyte.
</span><span />

<span>The ions are species with charge: cations are ions with positive charge and anions are ions with negative charge.
</span><span />

<span>The ions become the carrier of the charge so they are the responsible for the flow of current.
</span><span>
</span><span>
</span><span>So as the electrons are the carriers of the charge in the solid conductors (copper, aluminun, and others), the ions are the carriers of the charge in solutions.</span><span /><span>That is how the the electrolyte solutons conduct electricity.</span>

What are some changes that can be caused by sound energy? by electromagnetic energy?
Pavel [41]

Hearing loss due to sound energy damaging the nerve cells in the inner ear. Many animals behavior is influenced by sound energy. They learn to associate events with sounds, so they run when something crunches in the dry grass (might be a coyote), but won't be bothered by the sound of a waterfall. Mood is affected by sound energy. A wine glass can break with sound energy, if the frequency matches the resonant frequency of the wine glass and the amplitude is great enough (one Mythbusters show featured a professional singer who broke a wine glass with his voice without any amplification).

The heat of vaporization ΔHv of dichloromethane CH2Cl2 is 28.0 /kJmol . Calculate the change in entropy ΔS when 3.3g of dichloro
ella [17]

Answer:

\Delta _VS=3.48x10^{-3}kJ=3.48J

Explanation:

Hello,

In this case, the change in the entropy, by knowing the change in the enthalpy and the temperature for a vaporization process is given by:

\Delta _VS=\frac{\Delta _VH}{T_V}

Thus, we start by computing the change in the enthalpy for the 3.3g of dichloromethane  as shown below:

\Delta _VH=3.3gCH_2Cl_2 *\frac{1molCH_2Cl_2}{84.9gCH_2Cl_2}*28\frac{kJ}{molCH_2Cl_2} =1.09kJ

Finally, the change in the entropy, considering the temperature in kelvins:

\Delta _VS=\frac{1.09kJ}{(39.8+273.15)K}\\\\\Delta _VS=3.48x10^{-3}kJ=3.48J

Best regards.

Identify the type of reaction represented by each equation. a: h2 cl2 → 2hcl b: ch4 2o2 → co2 2h2o equation a represents a r
EastWind [94]

The right response is combustion reaction and synthesis reaction.

A hydrocarbon reacting chemically with oxygen to produce carbon dioxide and water is known as a combustion reaction.

hydrocarbon + O_{2} → CO_{2}  + H_{2}O

The term "synthesis reaction" refers to the chemical process wherein elements combine to generate a single product.

A + B → AB

Because hydrogen and chlorine combine to form the molecule of hydrochloric acid in their elemental states, this process is regarded as a synthesis reaction.

For A : H_{2} + Cl_{2} → 2HCl

Because hydrogen gas and chlorine gas are mixed in their elemental states to create the hydrochloric acid molecule, this process is regarded as a synthesis reaction.

For B: CH_{4}  + 2O_{2} → CO_{2} + 2H_{2}O

Because methane and oxygen combine to create carbon dioxide and water molecules, this reaction is regarded as a combustion reaction.
