Answer:
Mass = Number of neutrons + Atomic number (aka number of protons)
Explanation:
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:
The correct answer is B) Cl and Mg
Explanation:
An ionic bond is produced by the union of a cation and an anion. In this case, Mg would be the cation and Cl the anion. They will form the compound Magnesium Chloride (MgCl2):
Mg + Cl2 ----> MgCl2
Mg belongs to group 2 of the periodic table, that is, it has two valence electrons. In the case of Cl, it is in group 7 and has seven valence electrons (requires one electron to complete the octet).
C. Angiosperms (flowering plants)
