What are the list of processes?

Balanced equation:

2 Fe₂O₃ + 3 C → 4 Fe + 3 CO₂

number of moles of Fe₂O₃ = weight (g) / molar mass = (2.86 x 10⁴ g) / 159.69 g/mol = 179 moles

number of moles of C = (9.05 x 10³) / 12 = 754.16 moles

2 moles of Fe₂O₃ reacts with 3 moles of C

so 179 moles of Fe₂O₃ need 268.5 moles of C only

so carbon present in excess (754.16) and Fe₂O₃ is the limiting reactant so the number of moles used from Fe₂O₃ will be all the **179 moles**

**Answer:**

Hi there!

The correct answer is 2.29 x molecules

**Explanation:**

To convert from the moles to molecules:

1 mole = 6.022 x 10²³ molecules

so basically you multiply 3.8 by 6.022 x 10²³

and you get: 2.29 x

A familiar example is a lighted match. When a match is struck, friction heats the head to a temperature at which the chemicals react and generate more heat than can escape into the air, and they burn with a flame.

**Answer:**

962.2 K

**Explanation:**

Ideal Gas Law Equation:

PV = nRT

Writing a Equation to find T2:

PV = nRT

(P1V)/(nT1) = R = (P2V)/(nT2)

(P1)/(T1) = R = (P2)/(T2) V and n cancel out since they are constant.

(P1)/(T1) = (P2)/(T2)

T2 = (P2)(T1)/(P1)

Substituting Into the Equation:

T2 = (283 kPa * 170 K)/(50 kPa)

T2 = 962.2 K
