Answer:
answer is a because drugs do so to the person.
a. mass of iron = 69.92 g
b. percent yield = 93%

Percent yield is the compare of the amount of product obtained from a reaction with the amount you calculated
General formula:
Percent yield = (Actual yield / theoretical yield )x 100%
An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients
a.
Reaction
Fe₂O₃+3CO⇒2Fe+3CO₂
MW Fe₂O₃ : 159.69 g/mol
mol Fe₂O₃

mol Fe₂O₃ : mol Fe = 1 : 2
mol Fe :

mass of Fe(Ar=55.845 g/mol) :

b.
actual yield = 65 g
theoretical yield = 69.92 g
percent yield :

An increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often.
Answer:
The question specified 2 moles of potassium chloride. Clearly, there are 2 moles of chloride ions. How many moles of chloride ions in 95.2 g
Answer: Rate of reaction is an "extensive property". Rate of generation of a chemical species is an "intensive property"
Explanation:
- Let´s check out the Factors that affect the speed of reactions:
Temperature, Physical state of the reagents, Presence of a catalyst, Pressure, light, Concentration of the reagents.
When having a general chemical reaction like this:
aA + bB → cC + dD
Usually the rate of reaction is represented by the next equation
![Rate = k [A]^{x} [B]^{y}](https://tex.z-dn.net/?f=Rate%20%3D%20k%20%5BA%5D%5E%7Bx%7D%20%5BB%5D%5E%7By%7D)
Where k= constant
x, y = reactant orders
A, B = reactant concentration
As we can see in the last equation, the rate of reaction <u>depends directly of the amount of material present</u> in a sample, that is why it is an "extensive property"
- The rate of generation of a chemical species, depends of other factors like Temperature, Presence of a catalyst, Pressure. As we can see all the factors that allow the speed of generation of a new chemical species let us know that this is an<u> </u><u>intensive property</u><u> because it doesn´t depends of the amount of material.</u>
