Answer:
We'll have 8.0 moles Fe3O4 and 4.0 moles CO2
Explanation:
Step 1: data given
Number of moles Fe2O3 = 12.0 moles
Number of moles CO = 12.0 moles
Step 2: The balanced equation
3Fe2O3 +CO → 2Fe3O4 + CO2
Step 3: Calculate the limiting reactant
For 3 moles Fe2O3 we need 1 mol CO to produce 2 moles Fe3O4 and 1 mol CO2
Fe2O3 is the limiting reactant. It will completely be consumed (12.0 moles).
CO is in excess. There will react 12.0 / 3 = 4.0 moles
There will remain 12.0 - 4.0 = 8.0 moles
Step 4: Calculate moles products
For 3 moles Fe2O3 we need 1 mol CO to produce 2 moles Fe3O4 and 1 mol CO2
For 12.0 moles Fe2O3 we'll have 2/3 * 12.0 = 8.0 moles Fe3O4
For 12.0 moles Fe2O3 we'll have 12.0 / 3 = 4.0 moles CO2
We'll have 8.0 moles Fe3O4 and 4.0 moles CO2
Answer:
its C, because the cocunut tree gets energy from the sun and makes it into cocunut that is true

Answer:
Option B
Explanation:
All people who are asked to testify in a criminal case must first be issued a subpoena by law enforcement, is a "false statement" or option B. A subpoena is a request to appear in court which is usually given out by the attorneys who are a part of the case, the law enforcement does not give out subpoenas, so this is indeed a false statement.
Hope this helps.
Answer:
it's a precipitation reaction.
Explanation:
the solid produced is insoluble with water–making it a precipitate.
The absolute temprature is the limit to the highest and lowest temprature while the kinetic energy is the amunt of energy acquired by molecule to aid movement
