To find for the oxidizing agent, first let us write the half reactions of this complete chemical reaction:

Ca = Ca2+ + 2e- <span>
2 H+ + 2e- = H2</span>

 

The oxidizing agent would be the substance of the element that is reduced. We know that an element is reduced when an electron is added to it. In this case, the element being reduced is H. Therefore the oxidizing agent is HNO3.

 

Answer:

<span>HNO3</span>

Answer:

Nitric acid is an oxidizing agent in the given reaction.

Explanation:

Oxidizing agents : Agents which oxidize other substance and itself gets reduced. These agents undergoes reduction reactions.

Reducing agents : Agents which reduces the other substance and itself gets oxidized. These agents undergoes reduction reactions.

In the given reaction;

Ca(s)+2HNO_3(aq)\rightarrow Ca(NO_3)_2(aq)+H_2(g)

Oxidizing agent in the above reaction is a nitric acid which oxidizes calcium metal into calcium ionCa^{2+}

Ca\rightarrow Ca^{2+}+2e^-

Here calcium atom is undergoing oxidation reaction which is the reaction in which an atom looses its electrons and its oxidation state increases.

Amanda [17]

Answer:

5.2 ×10^-4 moles

Explanation:

Equation of reaction:

5C2O4^2- + 2MnO4^- +. 6H^+. ----------> 10CO2. +. 8H2O. + 2Mn^2+

From the information provided in the question:

Volume of potassium permanganate= 34.88ml

Concentration of potassium permanganate= 0.015M

Amount potassium permanganate= 0.015 × 34.88/1000= 5.2 ×10^-4 moles

What protects the Earth from meteorites and the sun's rays? (4 points)
inna [77]
I believe the answer is D. The atmosphere, different layers of the atmosphere can help in different ways! The stratosphere helps protect us from the sun's rays; The Mesophere is what helps protect us from meteorites! It's so cold that they burn up in that area.
