In a voltaic (galvanic) cell, oxidation occurs at the _____ and is where _____ in the salt bridge moves toward.

Anna11 [10]

In a voltaic (galvanic) cell, oxidation occurs at the <u>anode</u> and is where <u>anions</u> in the salt bridge moves toward.

<h3>What is Galvanic Cell ?</h3>

Galvanic Cell or Voltaic Cell is an electrochemical cell that converts the energy of spontaneous redox reactions into electrical energy. In galvanic cell oxidation occurs at the anode and reduction occurs at the cathode. The anode is positive and cathode is negative, anode attracts anions from solution in an electrolytic cell.

Thus from the above conclusion we can say that In a voltaic (galvanic) cell, oxidation occurs at the <u>anode</u> and is where <u>anions</u> in the salt bridge moves toward.

Which of the following is an example of electrical energy being converted to chemical energy?

marishachu [46]

The correct answer is option D, that is, a storage battery is charged using an electric current.

The transformation of one form of energy into another, generally to transform the energy into more useful kind is known as energy conversion. The energy can neither be created nor be destroyed, it can only be transformed. The different forms of energy comprise light, heat, mechanical, electrical, sound, nuclear, and sound.

In the given question, the charging of a storage battery using electric current is an example of electrical energy being converted into chemical energy.

Andre45 [30]

<span>Answer: (16.2 g C2H6O2) / (62.0678 g C2H6O2/mol) / (0.0982 kg) = 3.9704 mol/kg = 3.9704 m a.) (3.9704 m) x (1.86 Â°C/m) = 7.38 Â°C change 0.00Â°C - 7.38 Â°C = - 7.38 Â°C b.) (3.9704 m) x (0.512 Â°C/m) = 2.03 Â°C change 100.00Â°C + 2.03 Â°C = 102.03 Â°C</span>
