4. A galvanic cell is formed when two metals are immersed in solu- tions differing in concentration 1 when two different metals
Vanyuwa [196]

A galvanic cell is formed when two metals are immersed in solutions differing in concentration, when two different metals are immersed.

<h3><u>What is a </u><u>Galvanic</u><u> </u><u>cell</u><u> ?</u></h3>
  • In order to provide a pathway for the flow of electrons along that wire, the galvanic cell makes use of the ability to split the flow of electrons during the oxidation and reduction processes.
  • It forces a half-reaction and connects each to the other with a wire.
  • A galvanic cell is an electrochemical device that converts chemical redox reaction energy into electrical energy.
  • Electrically, it has a potential of 1.1 V. Oxidation takes place at the anode, which is a negative plate in galvanic cells. It is a positive plate where the reduction happens.
  • An electrochemical device called a galvanic cell transforms chemical energy's free energy into electrical energy. A photogalvanic cell produces species that are photochemically reactive.

explain how density can be used as a conversion factor to convert the volume of an object to the mass of the object, and vice ve
Elan Coil [88]
The density of a substance tells you the mass of exactly one unit of volume of that substance. This essentially means that density can be used as a conversion factor to go from the mass of a sample to the volume it occupies, or vice versa. This means that every milliliter of the substance has a total mass of 1.50 grams

Please help me with this question number 5!!
shtirl [24]
The answer is B, the electrolysis of water. One cannot be the answer since the condensation of steam requires a loss of heat, an exothermic reaction. Numbers 2 and 3 cannot be correct either as they do not indicate energy in the chemical equation, and so it must be balanced throughout. Meaning that the only possible answer is B.
