Suppose the gas resulting from the sublimation of 1.00 g carbon dioxide is collected over water at 25.0◦c into a 1.00 l containe

jeyben [28]

Answer:

0.55 atm

Explanation:

First of all, we need to calculate the number of moles corresponding to 1.00 g of carbon dioxide. This is given by

$n=\frac{m}{M_m}$

where

m = 1.00 g is the mass of the gas

Mm = 44.0 g/mol is the molar mass of the gas

Substituting,

$n=\frac{1.00 g}{44.0 g/mol}=0.0227 mol$

Now we can find the pressure of the gas by using the ideal gas law:

$pV=nRT$

where

p is the gas pressure

V = 1.00 L is the volume

n = 0.0227 mol is the number of moles

R = 0.082 L/(atm K mol) is the gas constant

T = 25.0 C + 273 = 298 K is the temperature of the gas

Solving the formula for p, we find

$p=\frac{nRT}{V}=\frac{(0.0227 mol)(0.082 L/(atm K mol))(298 K)}{1.00 L}=0.55 atm$

Is this equation completely balanced? 2C8H8 + 25O2 8CO2 + 18H2O No, because the number of carbon, hydrogen & oxygen atoms on

Sergio039 [100]

So to make it clear let's break the equation down species by species and assess the number of each species on bothe sides of the equation:
2C₈H₈ + 25O₂ → 8CO₂ + 18H₂O
LHS: C - 16 RHS: C - 8
H - 16 H - 36
O - 50 O - 34

Thus based on that it is evident that the equation is not quite balanced. This therefore means a "No, because the number of carbon, hydrogen & oxygen atoms on both sides of the equation are not equal."

The actual balance equation would be C₈H₈ + 10O₂ → 8CO₂ + 4H₂O
