Answer:

electrolysis is the correct answer.

Explanation:

Water is decomposed into hydrogen and oxygen gases using electricity. A Hoffman electrolysis apparatus collects the two gases separately and shows the 2 to 1 ratio nicely. ... Hoffman electrolysis apparatus. 2 electrodes - one is nichrome wire and the other is platinum wire and foil.

Go look up Hoffman apparatus.

<h3>Answer:</h3>

Electrolysis

<h3>Explanation:</h3>

Electrolysis refers to the process of decomposing an electrolyte by passing an electric current through it.
Electrolytes are ionic compounds either in molten or aqueous form that may be decomposed by passing an electric current through them.
Water is an example of an electrolyte that can be decomposed using electrolysis.
During electrolysis cations undergo reduction at the cathode while anions undergo oxidation at the anode.

In this case;

At the Cathode;

4H⁺(aq) + 4e → 2H₂(g)

At the Anode;

4OH⁻(aq) → H₂O(l) + O₂(g) + 4e

A carbon-carbon double bond has a greater bond energy than a carbon-carbon single bond. Because of the greater bond energy, a ca

Ronch [10]

<u>Answer:</u> Carbon-carbon double bond is stronger and shorter than the single bond.

<u>Explanation:</u>

It is given that carbon-carbon double bond has greater energy than the carbon-carbon single bond.

Bond energy is directly proportional to the bond strength, which means that the double bond will have greater strength than single bond and triple bond has the greatest strength of all the bonds.

$\text{Bond energy}\propto \text{Bond strength}$

Bond energy is inversely proportional to the bond length of the carbon-carbon bond. This means that more is the bond energy, shorter will be the bond and vice-versa.

$\text{Bond energy}\propto \frac{1}{\text{Bond Length}}$

Hence, carbon-carbon double bond is stronger and shorter than the single bond.

A 0.753 g sample of a monoprotic acid is dissolved in water and titrated with 0.250 M NaOH. What is the molar mass of the acid i

Alexeev081 [22]

Answer:

$MM_{acid}=140.1g/mol$

Explanation:

Hello,

In this case, since the acid is monoprotic, we can notice a 1:1 molar ratio between, therefore, for the titration at the equivalence point, we have:

$n_{acid}=n_{base} \\\\V_{acid}M_{acid}=V_{base}M_{base}\\\\n_{acid}=V_{base}M_{base}$

Thus, solving for the moles of the acid, we obtain:

$n_{acid}=0.0215L*0.250\frac{mol}{L}=5.375x10^{-3}mol$

Then, by using the mass of the acid, we compute its molar mass:

$MM_{acid}=\frac{0.753g}{5.375x10^{-5}mol} \\\\MM_{acid}=140.1g/mol$

Regards.
