Answer:
43.05 moles of Al needed to react with 28.7 moles of FeO.
Explanation:
Given data:
Moles of FeO = 28.7 mol
Moles of Al needed to react with FeO = ?
Solution:
Chemical equation:
2Al + 3FeO → 3Fe + Al₂O₃
Now we will compare the moles of Al with FeO.
FeO : Al
2 : 3
28.7 : 3/2×28.7 = 43.05 mol
Thus 43.05 moles of Al needed to react with 28.7 moles of FeO.
1. <em>Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period. </em>
<em>2. Physical state of the reactants and surface area.</em>
Answer:
A) "Diversity increased because Ford hired immigrants from many different countries." I believe this is the answer.
Explanation:
Answer:
Greater the mass
Greater kinetic energy
Velocity
Greater kinetic energy
Mass and velocity
Explanation:
We know that kinetic energy of object
Where m=Mass of object
v=Velocity of object
Kinetic energy is directly proportional to mass and velocity of object.
When mass of object is greater then the object has greater kinetic energy when the mass of object is small then the object has small kinetic energy.
When the velocity of object is greater then the object has greater kinetic energy when the velocity of object is small then the object has small kinetic energy.
The greater the mass of an object moves,the greater the kinetic energy it has.
The greater the velocity of a moving object,the greater kinetic energy it has.
Kinetic energy depends on both mass and velocity of object.
Answer: 20 I think
Explanation:
1 in each corner, 3 across from it. 3x4=12 plus one next to each is 20
