Answer:
The correct answer is : It is a salt because it is formed by the reaction of an acid and a base.
Explanation:
Sodium chloride is formed from the neutralization reaction between a strong acid (hydrochloric acid) and a strong base (sodium hydroxide):
HCl + NaOH ---> NaCl + H20
By reacting strong acid and base, they neutralize each other resulting in a salt (NaCl) and water.
Corresponds to an exothermic reaction (heat is released).
Answer:
A
Explanation:
Surface water percolates downwards to join the aquifer or the water table ultimately forming ground water
<span>a) Oxidation state of Ba in reactant: 0
In product: +2.
</span><span>Oxidation state of Zn in reactant: +2.
In product: 0.
</span><span>Oxidation state of S in reactant: +6
In product: +6.
</span><span>Oxidation state of O in reactant: -2.
In product: -2.
This is redox reaction because elements change their oxidation states (barium and zinc).
</span>b) Oxidation reaction: Ba⁰ → Ba²⁺ + 2e⁻.
Reduction reaction: Zn²⁺ + 2e⁻ → Zn⁰.
c) Barium is oxidized (increase of oxidation number) and zinc is reduced (decrease of oxidation number).
d) <span> The oxidizing agent is zinc (gain electrons) and the reducing agent is barium (lose electrons).</span>
The answer for this would be 69.6
Answer:
I believe it is Location C because northern is up and southern is down.
Explanation:
So the opposite of location A is C. Location A has the sun on it so I am assuming that is the Northern Hemsisphere. I really hope I am right.
