Answer: avogadros number/constant
Explanation:
Answer:
Oxygen is oxidized and hydrogen is reduced.
Explanation:
Let's consider the redox reaction during the electrolysis of water in an electrolytic cell.
2 H₂O ⇒ 2 H₂ + O₂
The corresponding half-reactions are:
2 e⁻ + 2 H₂O ⇒ H₂ + 2 OH⁻
2 H₂O ⇒ O₂ + 4 H⁺ + 4 e⁻
Oxygen is oxidized since its oxidation number increases from -2 to 0.
Hydrogen is reduced since its oxidation number decreases from +1 to 0.
Answer:
The fox who shed their heavy coat in the summer.
Explanation:
If a fox has the ability to shed its coat in the summer, it will have no difficulties adapting to new temperatures even during winter. However, the heavy-coated one will.
Answer: a. The elements iron in the nail and oxygen from the air combine to form the compound rust.
Iron, Fe: is an element
Oxygen, O: is an element
Rust, Fe3O4: this formula identifies the product as a compound
I think Thermodynamics is the aspect of a substance that contributes to a high or a low entropy. Entropy is the measure of chaos or disorder in a closed system. Entropy can be changed by a number of factors, for example, changing to a higher temperature increase entropy, change of states from solid to liquid and from liquid to gas causes changes in entropy, more bonds in a substance increases entropy, among other factors.
