Ammonia synthesis can be done by Haber process. N₂ gas and H₂ gas are used as the reactants. <span>The balanced reaction equation is
</span>N₂(g) + 3H₂(g) ⇄ 2NH₃(g) + energy

This is a reversible process and the conditions as follows,
1. Pressure
should be 150 - 200 atm
2. Temperature
is between 450 - 500 °C
3. Catalyst is iron

If you have 40 grams of potassium nitrate in 100 grams of water at 20 C:
anygoal [31]

Answer:

Explanation:The final homogenous solution, after cooling it to 40°C, will contain 47 g of potassium sulfate disolved in 150 g of water, so you can calculate the amount disolved per 100 g of water in this way:

[47 g of solute / 150 g of water] * 100 g of g of water = 31.33 grams of solute in 100 g of water.

So, when you compare with the solutiblity, 15 g of solute / 100 g of water, you realize that the solution has more solute dissolved with means that it is supersaturated.

To make a saturated solution, 15 grams of potassium sulfate would dissolve in 100 g of water.

In the reaction Fe2O3 + 3CO a 2Fe + 3CO2, 10 moles of solid iron and 15 moles of carbon dioxide are produced from 5 moles of iro
Schach [20]

Answer:

Ratio is 3:2

3CO = 2Fe or 1.5 CO = 1 Fe

Explanation:

Fe2O3 + 3CO = 2Fe + 3CO2

Fe2O3 = Iron (|||) oxide

CO = Carbon monoxide

Fe = Solid Iron

CO2 = Carbon dioxide

Excellent is already balanced.

10 Moles Fe and 15 Moles of CO2

5 Moles Fe2O3 + 15 Moles 3CO = 10 Moles Fe + 15 Moles 3CO2

What is the ratio of carbon monoxide to solid iron

Ratio is 3:2 or 1.5 CO = 1 Fe

A sample of monochloro pentaborane (9), b5h8cl, has a mass of 20.1 g. what amount, in moles, does this mass represent?
dolphi86 [110]

The number of moles in monochloro pentaborane (9) B_5H_8Cl is 0.37056.

We know that ,

Number of moles =   Given mass/ Molar mass

Given mass of monochloro pentaborane (9) is 20.1 g

The molar mass of monochloro pentaborane (9) is

                                        =  5*B +  8*H + Cl

                                        =  5* 10.811 + 8 * 1 + 35.453

                                        = 54.241

Thus number of moles =  20.1/54.241

                                      = 0.37056

A piece of chocolate with a mass of 8 grams melts. What is the mass of the melted chocolate?
LiRa [457]

Answer:

The mass of the melted chocolate is 8 grams.

Explanation:

When something is melted including chocolate the mass remain the same or does not change, it is only the motion of the particles that changes and this is called law of conservation of mass.

The law states that mass can neither be created nor destroyed during chemical reaction but it remain the same.
