1. By Newton's second law, the mathematical relationship between force, mass and acceleration can be described.
2. An object will undergo acceleration only when an unbalanced force will be acting on any object.
Answer:
Explanation:
1. The mathematical relationship between force, mass and acceleration is done in the Newton's second law of motion. In this law, it is stated that any external unbalanced force acting on any object will be equal to the rate of change of momentum. In other words, the external unbalanced force will be proportional to the acceleration exerted on the object and also to the mass of the object.
Since, momentum p = mass * velocity = mv
Since, the mass will be constant, dm/dt = 0, so F = ma
2. Also from this law, it can be understood that an object will undergo acceleration only when an unbalanced force will be acting on any object.
Answer:
1. 4FeCl3 + 3O2 → 2Fe2O3 + 6Cl2
2. 6 moles of Cl2
Explanation:
1. The balanced equation for the reaction. This is illustrated below:
4FeCl3 + 3O2 → 2Fe2O3 + 6Cl2
2. Determination of the number of mole of Cl2 produce when 4 moles of FeCl3 react with 4 moles. To obtain the number of mole of Cl2 produced, we must determine which reactant is the limiting reactant.
This is illustrated below:
From the balanced equation above,
4 moles of FeCl3 reacted with 3 moles of O2.
Since lesser amount of O2 (i.e 3 moles) than what was given (i.e 4 moles) is needed to react completely with 4 moles of FeCl3, therefore FeCl3 is the limiting reactant and O2 is the excess reactant.
Finally, we can obtain the number of mole Cl2 produced from the reaction as follow:
Note: the limiting reactant is used as it will produce the maximum yield of the reaction since all of it is used up in the reaction.
From the balanced equation above,
4 moles of FeCl3 will react to produced 6 moles of Cl2.
Answer:
It is called Ionization Energy.
