A voltaic cell spontaneously converts1) electrical energy to chemical energy(2) chemical energy to electrical energy(3) electric
Varvara68 [4.7K]
A voltaic cell spontaneously converts chemical energy to electrical energy. The correct option among all the options given in the question is option "2". Actually voltaic cell is an electrochemical cell that converts the chemical contained within it by the process of chemical reaction to produce electrical energy. The voltaic cell contains an anode and a cathode. Anode is an electrode where the oxidation occurs and cathode is the electrode where reduction occurs. The oxidation and the reduction part occurs in two separate parts of the cell known as half-cell.

choli [55]

Answer:

trigonal planar

Explanation:

The molecule SO3 is of the type AX3. The molecule is symmetrical and non polar.

There are three regions of electron density in the molecule. This corresponds to a trigonal planar geometry. This means that the three oxygen atoms are arranged at the corners of a triangle.  The bond angle is 120 degrees.

2. A block of aluminum with a mass of 140g is cooled from 98.4oC to 62.2oC with a release of 1137J of heat. From these data, cal
NeTakaya
Q =  M * C *ΔT

Q / <span>ΔT  = M

</span>Δf - Δi =  98.4ºC - 62.2ºC = 36.2ºC
<span>
C = 1137 J / 140 * 36.2

C = 1137 / 5068

C = 0.224 J/gºC</span>

Select the property that is not a characteristic of an ideal recrystallization solvent.
dybincka [34]

Answer:

(C) The recrystallization solvent should be nonvolatile.

Explanation:

Recrystallization is the separation technique which is used to purify the solid compounds in their crystal or amorphous form.

Some properties follow the recrystallization process as:

The solids are more soluble in hot solvent as compared to the solubility in the cold solvent.

The solvent must have lower boiling point and can be volatile easily.

The solvent should not react with the compound.

The impurities must be soluble in the cool solvent, so that only the pure product crystallizes.

Hence, Answer - C which is not an ideal characteristic.
