How are solubility and temperature generally related in a system consisting of a solid solute and a liquid solvent?

1 answer:

8 0

Solubility and temperatures are directly related. The higher the temperature of the solvent, the higher the solubility of the solute in the solvent.

Dissolving a solute in a solvent is an endothermic process hence providing heat favors the process. Higher temperatures cause the molecules of the solvent to have high kinetic energy hence bombard each other and with that of the solute with high frequency. This then ensures fast diffusion of the solute particles in the solvent.

What gets oxidized in a galvanic cell made with magnesium and zinc electrodes?

ankoles [38]

Answer: Magnesium

Explanation:

Galvanic cell is a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy.

The standard reduction potential for magnesium and zinc are as follows:

$E^0_{[Mg^{2+}/Mg]}= -2.37V$

$E^0_{[Zn^{2+}/Zn]}=-0.76V$

Reduction takes place easily if the standard reduction potential is higher (positive) and oxidation takes place easily if the standard reduction potential is less (more negative).

Here Mg undergoes oxidation by loss of electrons, thus act as anode. Zinc undergoes reduction by gain of electrons and thus act as cathode.

$Mg\rightarrow Mg^{2+}+2e^-$

$Zn^{2+}+2e^-\rightarrow Zn$

Thus magnesium gets oxidized.

Which is the following is a decomposition reaction

lora16 [44]

The equation that is a decomposition reaction is

PbCO3(s) ---> PbO(s) + CO2(g)

That is option D.

<h3>Properties of a decomposition reaction</h3>

A chemical reaction is defined as the combination of substances called reactants to form a product. The various types of chemical reaction include:

synthesis reaction

combustion reaction

decomposition reaction

single or double replacement reaction

Decomposition reaction is that type of chemical reaction in which the reactant breaks down to form two or more products.

Therefore the heating of lead (II) carbonate is a decomposition reaction.
