1. So 27.3 g Fe is 0.4911 mol (27.3 / 55.58). 45.8 g O is 2.862 mol. Because of the stoichiometry, 3/4 as much oxygen as iron gets consumed. For the 0.4911 mol Fe consumed, 0.3683 mol O is consumed. 2.862-0.3863 = 2.4757 mol, or 39.6 g O is left.

2. Hydrogen is the limiting reactant for these quantities. 2/3 as much ammonia is produced as hydrogen is consumed, so for 5.0 mol H2, that's 3.33 mol NH3.

Make sense?

Can someone please help me with the correct formula for this?
Anarel [89]

Answer:

C₂H₄O

CH₃CHO

Explanation:

I'm not sure if you want the molecular formula or the condensed structure, but I will give you both.

Molecular formula:

You have 2 carbons (C₂), 4 hydrogens (H₄), and 1 oxygen (O).  The molecular formula will be C₂H₄O.

Condensed Structure:

You have a carbon bonded to three hydrogens (CH₃).  This carbon is bonded to a carbon that is bonded to a hydrogen and oxygen (CHO).  The condensed structure will be CH₃CHO.

A sample of nitrogen gas, (N2), occupies 45.0 mL at 27.00∘C and 80.0 kPa. What will be the pressure if the gas is cooled to −73.
maxonik [38]

Answer:

The new pressure is 53.3 kPa

Explanation:

This problem can be solved by this law. when the volume remains constant, pressure changes directly proportional as the Aboslute T° is modified.

T° increase → Pressure increase

T° decrease → Pressure decrease

In this case, temperature was really decreased. So the pressure must be lower.

P₁ / T₁ = P₂ / T₂

80 kPa / 300K =  P₂/200K

(80 kPa / 300K) . 200 K = P₂ →  53.3 kPa
