Answer:
Oxidation: a type of chemical reaction where one or more electrons are lost.
Oxidation State / Number: a number assigned to an atom describing its degree of oxidation, meaning how many electrons it has gained or lost.
Reduction: a type of chemical reaction where one or more electrons are gained.
Oxidation-Reduction Reaction: a chemical reaction where oxidation and reduction occurs simultaneously
Explanation:
Reduction always occurs at cathode
Oxidation always occurs in anode
These two process occurs in same way independent of nature of cell whether voltaic or electrolytic.
Answer:
finding the mass percentage oven element in a compound might sound complicated, but the calculation is simple. For example, to determine the mass percentage of hydrogen in water H2O, divide the major mass of hydrogen by the total molar mass of water and then multiply the result by 100

D. Allotrope
<h3>
Explanation:</h3>
What is allotropy?
- Allotropy refers to the existence of an element in more than one physical forms.
- Allotropes are therefore different forms of an element with different physical properties or chemical arrangements.
What are some examples of allotropes?
- Examples of elements that exhibit allotropy include, sulfur and carbon.
- Allotropes of carbon are diamond and graphite.
- Allotropes of sulfur are monoclinic sulfur and rhombic sulfur.
The suggested answers are for K=298 degrees and the nearest correct answer seems to be increase the room temperature by 22 degrees Fahrenheit. But by calculation, for 300 K, then convert 300k to degrees Celsius = 300-273.15=26.85 degrees celsius. Then convert the 26.85 to degrees F, so F=9/5C + 32= 48.33+32=80.33-55F (present room temperature)=25.33 degrees F to increase the room temperature by.
