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.

Answer:
Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen gas. ... Cellular respiration is the complementary reaction to photosynthesis, because it is the reaction that cells use to break down glucose molecules and release ATP.
Answer:
333N
Explanation:
Once we have the object's mass, we can find the weight by multiplying it by the gravitational force, which it is subject to. Being that Mars has a gravitational force of 3.7m/s2, we multiply the object's mass by this quantity to calculate an object's weight on mars.
So an object or person on Mars would weigh 37.83% its weight on earth. Therefore, a person would be much lighter on mars. Conversely, a person is 62.17% heavier on earth than on Mars.
Answer:
<em>the <u>valency of an element</u> is its combining capacity that is the number of electrons it requires to lose, gain or share in order to become neutral.</em>
[ An element can become neutral if it completes it's octet. That is if an element has 8 electrons in it'd outermost shell then it is considered neutral ]
- The valence of Magnesium is 2 because it requires to lose 2 electrons to become neutral.
- whereas, the valence of Oxygen is 2 because it needs to gain 2 electrons to become stable.
Hence they both have the same valence.
One may say that oxygen's valence is -2 while that of Magnesium is + 2. It's meaning is still the same but "-" sign indicates that oxygen will be gaining electrons in the process of becoming stable.
