The mass in grams of NH₃ produced from the reaction is 3.4 g
<h3>Balanced equation</h3>
We'll begin by writing the balanced equation for the reaction. This illustrated below:
N₂ + 3H₂ -> 2NH₃
From the balanced equation above,
1 dm³ of N₂ reacted to produced 2 dm³ NH₃
<h3>How to determine the volume of NH₃ produced</h3>
From the balanced equation above,
1 dm³ of N₂ reacted to produced 2 dm³ NH₃
Therefore,
2.24 dm³ of N₂ will react to produce = 2.24 × 2 = 4.48 dm³ of NH₃
<h3>How to determine the mass of NH₃ produced</h3>
We'll begin by obtained the mole of 4.48 dm³ of NH₃. Details below:
22.4 dm³ = 1 mole NH₃
Therefore,
4.48 dm³ = 4.48 / 22.4
4.48 dm³ = 0.2 mole of NH₃
Finally, we shall determine the mass of NH₃ as follow:
- Molar mass of NH₃ = 17 g/mol
- Mole of NH₃ = 0.2 mole
- Mass of NH₃ =?
Mass = mole × molar mass
Mass of NH₃ = 0.2 × 17
Mass of NH₃ = 3.4 g

Answer:
a) 68.9 b/ ft²
b) 57.416
Explanation:
Volume of the cylindrical open container V = 5 gal
= (5)(231)
= 11155 in³
different diagrammatic expression has been shown in the attached file below for clear understanding.
Area A = 120 in²
V = hA
= 
= 9.625 in
Upward acceleration , 
= 68.9 b/ ft²
b) The flowchart for the resultant force is shown in the diagram below:
with that:
Thus, the resultant force that the container exert on the floor of the elevator during this acceleration = 57.416
Answer:
Volatile
Explanation:
Nonmetal are usually volatile, which means it evaporate easily.

Explanation:
Wind is a renewable source of energy widely used as a source of energy in order to minimize the pollution that results from some other sources of non renewable energy.
Wind energy has the advantage of;
1) being a renewable source of energy hence it can be reused and it is not easily depleted.
2) it does not lead to any form of environmental pollution.
On the other hand, a lot of space is required in order to mount as many windmills as possible in order to generate enough electricity to serve a large area. Thus, the disadvantages of wind energy are;
1) A large expanse of land is required in order to generate a meaningful quantity of energy.
2) The occurrence of wind is inconsistent hence generation of energy is not steady.
