Alona [7]

Answer:

The net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide:

$2Fe_2O_3 (s) +6C (s) + 3O_2 (g)\rightarrow 4Fe (s) + 6CO_2 (g)$

Explanation:

Step 1: Carbon and oxygen react to form carbon monoxide:

$2C (s) + O_2 (g)\rightarrow 2CO (g)$ ..[1]

Step 2: Iron(III) oxide and carbon monoxide react to form iron and carbon dioxide:

$Fe_2O_3 (s) + 3CO (g)\rightarrow 2Fe (s) + 3CO_2 (g)$ ..[2]

The net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide can be obtained by :

3 × [1] + 2 × [2]

$2Fe_2O_3 (s) + 6CO (g)+6C (s) + 3O_2 (g)\rightarrow 4Fe (s) + 6CO_2 (g)+6CO(g)$

CO gas will gas cancel out form both sides ans we will get the net chemical equation:

$2Fe_2O_3 (s) +6C (s) + 3O_2 (g)\rightarrow 4Fe (s) + 6CO_2 (g)$

According to reaction, 2 moles of ferric oxide reacts with 6 moles of carbon and 3 moles of oxygen gas to give 4 moles of iron and 6 moles pf carbon dioxide gas.

A 1.00 L sample of a gas at a pressure of 1.000atm is compressed to 0.25 L at a constanttemperature. What is the new pressure of

lord [1]

Answer:

<h3>The answer is 4 atm </h3>

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

Since we are finding the new pressure

$P_2 = \frac{P_1V_1}{V_2} \\$

From the question we have

$P_2 = \frac{1 \times 1}{0.25} = \frac{1}{0.25} \\$

We have the final answer as

Hope this helps you
