Which diagram shows a voltaic cell?

Chemistry

Since you have not included the figures with the diagrams to select the right answer, I am going to explain the main differences that lead you to differentiate electrochemical cells.

There are four important terms needed to identify the electrochemical cells: electrolysis, electrochemical cells, electrolitc cells and voltaic cells.

1) Electrochemical cell: is a device that uses a chemical reaction (redox reaction) to produce electricity or that uses electricity to product a chemical reaction.

2) Electrolysis: is the production of a chemical reaction using electricity.

3) Electroltic cell: is one of the two types of electrochemical cell. It is that in which electricity is used  to produce the chemical reaction, i.e. where electrolysis happens. For example, the decomposition of sodium chloride brines is done in an electrolitic cell.

4) Galvanic cell: is the other type of electrochemical cell. It is that in which chemical reactions (redox reactions) produce electricity. The battery of the car is an example of a galvanic cell.

Here you are asked to identify which diagram shows a voltaic cell.So, you need to lool at:

- a redox reaction is happening

- this redox reaction is producing electricity (not that the electricity is producing the reaction)

Remember that a redox reaction is where some atoms are being reduced (gaining electros) and others are being oxidized (losing electrons).

Tha information will let you to choose the righ diagram.

CH3CI, CF4, HCI, NH3 which would have the lowest boiling point
Sergio [31]

Boiling point of a compound is determined by the strength of intermolecular forces of attraction between the molecules present in it. Stronger the intermolecular forces of attraction, higher will be the boiling point.

Ionic compounds show ion-ion interactions which are the strongest among all. Ion-dipole interactions are shown when ionic solutes are dissolved in polar solvents. Hydrogen bonding is also a relatively stronger force that is present between H atom and an electronegative atom like F, O and N(NH_{3}) . All polar molecules show dipole-dipole interaction (CH_{3}Cland HCl). Dispersion forces are the weakest intermolecular forces due to momentary dipoles between electron clouds and nucleus.

Among the given compounds, CF_{4}has dispersion forces as the major intermolecular forces of attraction. So they they exhibit the weakest IMF, hence have the lowest boiling point.

Which change in the h+ ion concentration of an aqueous solution represents a decrease of one unit on the ph scale?
melisa1 [442]
The answer would be a tenfold increase<span>
The pH scale is calculated based on the concentration of H+ ion in the solution. The formula is using log10, so to decrease 1 unit from the scale it will be 10^1= 10 fold of increase. For 2 </span>unit, you will need 10^2= 100 fold of increase.
