1. A gas having the following composition is burnt under a boiler with 50% excess air.

jeka94

The composition of the stack gas are :

$CH_4$ = 0.8713

$C_3H_8$ = 0.0202

CO = 0.107

<h3 /><h3>What is a mole fraction?</h3>

The ratio of the number of moles of one component of a solution or other mixture to the total number of moles representing all of the components.

Assuming 100 g of the stack gas. Calculate the mass of each species in this sample according to their percentages.

Mass of $CH_4$ : 70% of 100 g = 70 g

Mass of $C_3H_8$ : 15% of 100 g = 15 g

Mass of CO : 15% of 100 g = 15 g

Now calculate the number of moles of each species:

Number of moles of $CH_4$ : $\frac{70 g}{16.04 g/mol}$ = 4.3 mole

Number of moles of $C_3H_8$ : $\frac{15 g}{144.1 g/mol}$ = 0.10 mole

Mass of CO : $\frac{15 g}{28.01 g/mol}$ = 0.53 mole

Now to calculate the mole fraction of each we use the formula:

Mole fraction of $CH_4$ : $\frac{4.3}{4.935}$ = 0.8713

Mole fraction of $C_3H_8$ : $\frac{0.10}{4.935}$ = 0.0202

Mole fraction of CO : $\frac{0.53}{4.935}$ = 0.107

Hence, composition of the stack gas are:

$CH_4$ = 0.8713

$C_3H_8$ = 0.0202

CO = 0.107

Which of the following is unrelated to estimating vapor pressure? (a) Antoine's Equation (b) Cox charts (c) Gibb's phase rule (d

Bezzdna [24]

Answer:

Explanation:

Gibb's phase rule :

describe the relationship between the number of degrees fredoom in a closed system, the number of phases in equilibrium and the number of the system components.

f = c - p + 2

the above is no related to the estimation of the vapor pressure.

trace the path of a labeled carbon atom through the biological processes of photosynthesis and respiration. The atom will start

TiliK225 [7]

The carbon atom will get processed by going through the stomata of a leaf. It is then combined with energy to produce something called glocuse or a form or type of sugar. The sugar will be used as energy, tissue and starch for itself. That's basically the fate of the carbon.
