Explanation:
Answer:
the second one because it has heat waves sending out
<h2>Hello!</h2>
The answer is: -97.37° C
<h2>Why?</h2>
According to the Charles and Gay-Lussac's Law we have that:

Where:
<em>v</em> is the volume of the gas
<em>t</em> is the temperature of the gas
<em>k </em>is the proportionality constant
From the Gay-Lussac's Law we also have the following relation:

Since we need to find the new temperature (T2) we can use the last equation:

We are asked to find the temperature in Celsius degrees, so, we must convert the result (in K) to Celsius degrees:

So, the temperature is -97.37° C

Based on the given chemical equation, the value of coefficient that is used in the reaction before each molecule is 1.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those equation in which each element is present in equal amount on both side of the chemical reaction.
Given chemical reaction is:
BaO₂ + H₂SO₄ → H₂O₂ + BaSO₄
Above reaction is balanced as all elements are present in equal amounts on both sides. So, the value of coefficients is 1.
Hence the required coefficients is 1.
