WARRIOR [948]

Answer:

Molarity of HClO_{4} solution is 0.311 M

Explanation:

Neutralization reaction: 2HClO_{4}+Ba(OH)_{2}\rightarrow Ba(ClO_{4})_{2}+2H_{2}O

According to balanced reaction, 1 mol of Ba(OH)_{2} neutralizes 2 moles of HClO_{4}

Number of moles of Ba(OH)_{2} in 13.8 mL of 0.191 M Ba(OH)_{2} solution = \frac{0.191}{1000}\times 13.8moles = 0.00264moles

Let's assume molarity of HClO_{4} solution is C (M) then-

Number of moles of HClO_{4} in 17.0 mL of C (M) HClO_{4} solution = \frac{C}{1000}\times 17.0moles = 0.017Cmoles

Hence, 0.017C=(2\times 0.00264)

         or, C=0.311

So, molarity of HClO_{4} solution is 0.311 M

The given questions belongs to the concept of limiting reagent.

The number of moles of carbon dioxide produced when 4.6 moles of dioxygen reacts is 4.6 moles.

<h3 /><h3>What is Limiting Reagent ?</h3>

The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed.

Given ;

Moles of Oxygen = 4.6

To find;

Moles of Carbon di oxide = ?

The reaction that forms CO_2 is as follows:

C(s) + O_2(g) -->  CO_2(g)

This means that O_2 is consumed and  CO_2 is produced in a 1:1 ratio.

If we consume 4.6 mol  O_2, then we produce 4.6 mol  CO_2 .

Hence, 4.6 mol  CO_2 are produced when 4.6 mol of oxygen reacts.

ANSWER ASAP PLEASE!<br> Balance the following equation:<br> _Fe + _O₂ --&gt; _FeO₃
ira [324]
It would be. 2Fe + 3O2 ——> 2Fe03. You have to make oxygen 6 on both sides in order to balance, then you can do Fe. Which on the right would be 2 by making oxygen 6. Then add the 2 to the other side to balance it.
