2.) At what temperature in Celsius will a 1.0g sample of neon gas exert a pressure of 500 torr in a 5.01 L container. (Hint: use the Ideal Gas Law)

It is expected at 1.05 atm the solubility increases if compared to the solubility at 0.222 atm.

In general, an increase in pressure leads to an increase in solubility. In the same way, a decrease in pressure will decrease solubility.

Considering the pressure increased, the most likely result is for the solubility to proportinally increase.

Answer:

Explanation:

Answer:

Here, is the number of moles in the CO2. Substitute 0.20 g for weight and 44 g/mol for molecular weight of the CO2.

1 mol = 6.02.10²³ particles (atoms, molecules, ions)

mol CO₂ = 0.2 g : 44 g/mol = 0.0045

molecules = 0.0045 x 6.02 x 10²³ = 2.709 x 10²¹

The composition of the stack gas are :

[tex]CH_4[/tex]= 0.8713

[tex]C_3H_8[/tex] = 0.0202

CO = 0.107

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 [tex]CH_4[/tex] : 70% of 100 g = 70 g

Mass of [tex]C_3H_8[/tex] : 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 [tex]CH_4[/tex] : [tex]\frac{70 g}{16.04 g/mol}[/tex] = 4.3 mole

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

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

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

Mole fraction of [tex]CH_4[/tex]: [tex]\frac{4.3}{4.935}[/tex] = 0.8713

Mole fraction of [tex]C_3H_8[/tex] : [tex]\frac{0.10}{4.935}[/tex] = 0.0202

Mole fraction of CO : [tex]\frac{0.53}{4.935}[/tex] = 0.107

Hence, composition of the stack gas are:

[tex]CH_4[/tex] = 0.8713

[tex]C_3H_8[/tex] = 0.0202

CO = 0.107

The number of micrograms of contaminant each person will receive is 5,742.64 ug.

The number of micrograms of contaminant each person will receive is calculated as follows;

Amount of contaminant (mg) = (1.01 x 10⁻⁴ mg/mL) x 2.28 x 10⁴ L

Amount of contaminant (mg) = 2.3028 mg.L/mL

Amount of contaminant (mg) = (2.3028 mg.L/mL) x (1000 mL/L) = 2,302.8 mg

Amount of contaminant (ug) = 2,302.8 mg x 1000 ug/mg = 2,302,800 ug

=  (2,302,800 ug) / (401 persons)

= 5,742.64 ug per person

Answer:

0.500

Explanation:

We presume your "centroid ratio theorem" tells you that AG = 2·DG, so ...

 (x+7) = 2(x -15)

 x + 7 = 2x - 30 . . . . eliminate parentheses

 37 = x  . . . . . . . . . . .add 30-x

Then AG = 37+7 = 44

and DG = 37-15 = 22.

Of course, AD = AG +GD = 44 +22 = 66

Answer:

The salt bridge serves to complete the electrical circuit in the galvanic cell. It is pertinent that the salt bridge ions are in high concentrations as this allows electron mobility and keeps each half cell electronically neutral. The diluted salt bridge wuld cause a buildup of positive charge in the anode and negative charge in the cathode and the electrode half reactions which either reduce or oxidise species would halt. Causing the cell to stop producing electronic energy, impedeing the proper functioning of the galvanic cell.
