Answer:
The net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide:
Explanation:
Step 1: Carbon and oxygen react to form carbon monoxide:
..[1]
Step 2: Iron(III) oxide and carbon monoxide react to form iron and carbon dioxide:
..[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]
CO gas will gas cancel out form both sides ans we will get the net chemical equation:
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.
The final temperature of the sample of gas is 689.65 Kelvin.
<h3>What is the relation between temperature and pressure?</h3>
Relation between the temperature and pressure will be represented by the ideal gas equation PV = nRT, and for this question required equation is:
P₁/T₁ = P₂/T₂, where
P₁ & T₁ are the pressure and temperature of the initial sample.
P₂ & T₂ are the pressure and temperature of the final sample.
Pressure is in mmHg and on putting values from the question on the above equation, we get
T₂ = (810)(390.8) / (760) = 416.5 degree C = 689.65K
Hence required temperature of the sample is 689.65K.

Answer: 8 Moles of Oxygen
Explanation: The formula shows that there are (exactly) 4 oxygen atoms in each mole or formula unit. Therefore 4 * 2.00 = 8.
Osmosis deals only with D. Water. Diffusion and Osmosis are relatively the same thing besides the fact that water is largely incorporated with the osmosis.
It says
The majority of elements on the periodic table are ______________ (metals, nonmetals, or metalloids).
The periodic table on the left separates elements into three groups: the metals (green in the table), nonmetals (orange), and metalloids (blue). Most elements are metals.
