What statement is incorrect about this oxidation-reduction reaction? 2 SO2(g) + O2(g) → 2 SO3(g) What statement is incorrect abo
Leno4ka [110]

Answer:

The incorrect statement is: SO₂ gains electrons                      

Explanation:

A chemical reaction that involves the simultaneous transfer of electrons between two chemical species, is known as the redox reaction.

Given chemical reaction: 2SO₂(g) + O₂(g) → 2SO₃(g)

In this redox reaction, S is present in +4 oxidation state in SO₂ and +6 oxidation state SO₃. Whereas, O is present in 0 oxidation state in O₂ and -2 oxidation state in SO₃.

<u>Therefore, SO₂ loses electrons and thus gets oxidized. Whereas, O₂ gains electrons and thus gets reduced. </u>

<u>In this reaction, SO₂ is the reducing agent and O₂ is the oxidizing agent.</u>

15 grams of HCl should theoretically produce 0.42 grams of H2. The reaction actually produced 0.15 grams of H2. What is the perc
Helen [10]

Answer:

35.7%

Explanation:

The percent yield is calculated by the formula:

<em>[(actual yield) / (theoretical yield)] * 100</em>

In this case, the actual yield is 0.15 grams, and the theoretical yield is 0.42 grams. So, putting these values into the equation, we have:

\frac{0.15}{0.42} *100=0.357*100=35.7

Thus, the percent yield of H_2 is 35.7%.

Hope this helps!
