Answer:

Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.

Consider the following reaction: 3Fe(s) + 4H₂O(g) ➞ Fe₃O₄(s) + 4H₂(g). To answer the following question: "How many moles of hot

Elodia [21]

Answer: 2

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

$\text{Moles of} Fe_3O_4=\frac{275g}{233.5g/mol}=1.18moles$

$3Fe(s)+4H_2O(g)\rightarrow Fe_3O_4(s)+4H_2(g)$

According to stoichiometry :

1 mole of $Fe_3O_4$ are produced by = 4 moles of $H_2O$

Thus 1.18 moles of $Fe_3O_4$ will be produced by= $\frac{4}{1}\times 1.18=4.72moles$ of $H_2O$

Mass of $H_2O=moles\times {\text {Molar mass}}=4.72moles\times 18g/mol=85.0g$

Thus 85.0 g of $H_2O$ will be required and 2 steps are required to get the answer.

What mass of carbon dioxide (co2) can be produced from 15.6 g of c6h14 and excess oxygen?

madreJ [45]

C6H14+9.5O2=6CO2 +7H20
Number of moles of C6H14=15.6/86=0.1814 moles
so moles of CO2 = 6(0.1814)=1.088
As the c6h14 has 1 is to 6 ratio with co2
so
0.1814=mass/44
mass of co2 produced = 47.9 g
