Move anywhere and can be anywhere while it is in that phase
Is this a multi choice question?????????????????????
Answer:
<span>Chlorine (Cl) is the oxidizing agent because it gains an electron.
Explanation:
Reaction is as follow,
</span><span> Cl</span>₂<span> (aq) + 2 Br</span>⁻<span> (aq) </span>→ <span> 2Cl(aq) + Br</span>₂ <span>(aq)
Oxidation Reaction:
2 Br</span>⁻ → Br₂ + 2 e⁻
Two atoms of Br⁻ (Bromide) looses two electrons to form Br₂ molecule. Hence it is oxidized and is acting as reducing agent.
Reduction Reaction:
Cl₂ + 2 e⁻ → 2 Cl⁻
One molecule of Cl₂ gains two electrons to form two chloride ions (Cl⁻). Therefore, it is reduced and has oxidized Br⁻, Hence, acting as a oxidizing agent.
Answer:
Explanation:
Columns and rows used in the periodic classification of elements shows trends in the properties of elements.
The periodic columns are called groups and they denote vertical arrangement of elements.
The horizontal rows are the periods.
- Groups and Periods provides a very simple way to classify elements.
- They reflect trends among different elements that are found in nature. Following these groups and periods, it is even possible to predict the nature of an undiscovered element.
- Certain parts of the table have some unique elements on them with some distinctive properties that distinguish them from others.
- The atomic number is the basis of this classification. By this, it is possible to delineate that elements with similar properties are located on the same group.
