Answer:
Chemical energy is energy stored in the structure of molecules within the bonds between atoms. Energy can be added or released from a molecule by changing the arrangement of electrons (rearranging chemical bonds).
Explanation:
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

because the model makes the concepts easier to understand
Explanation:
A model would be useful because they make concepts easier to understand.
Models are abstractions of the real world.
- Scientists use model to make concepts easier to understand
- Models take parts of the real world and simulates them.
- They help remove the ambiguity that might be associated with studying the real world.

increase the rate of chemical change.
Explanation:
The reaction of the metal oxide with water to form a base in the presence of a spike in temperature will lead to an increase in the rate of chemical change.
Temperature change has considerable effect on reaction rates.
- Temperature is directly proportional to the average kinetic energy of reacting particles.
- Reaction rates varies directly with a spike in temperature.
- It has been known that for every 10°C rise in temperature, above the room temperature, reaction rates become double or tripled.
- Temperature increases the kinetic energy of each of the reacting particles.
- Many of the reacting particles also acquires an energy greater than or equal to the activation energy of the reaction.
- The frequency of ordinary collisions and effective collisions per unit time increases.
