A 200.0mL closed flask contains 2.000mol of carbon monoxide gas and 2.000mol of oxygen gas at the temperature of 300.0K. How man

Answer:

There will react 0.400 moles of oxygen.

Explanation:

<u>Step 1:</u> Data given

Volume of the closed flask = 200.00 mL = 0.2 L

Number of moles of CO = 2.000 mol

Number of moles of O2 = 2.000 mol

Temperature = 300.0 K

Pressure decreases with 10%

<u>Step 2</u>: The balanced equation

2CO(g)+O2(g)⟶2CO2(g)

<u>Step 3</u>: Calculate the initial pressure of the flask before the reaction

P = nRT/V

⇒ with n = the number of moles (2.000 moles CO + 2.000 moles O2 = 4.000 moles)

⇒ R is gas constant (0.08206 atm*L/mol*K)

⇒T = the  temperature = 300.0K

⇒ V = the volume = 200.0 mL = 0.2 L

P = (4 * 0.08206*300)/0.2

P = 492.36 atm

<u>Step 4:</u> When the pressure is 10 % decreased:

The final pressure = 492.36 - 49.236 = 443.124 atm

<u>Step 5:</u> Calculate the number of moles

n = PV/RT

⇒ with n = the number of moles

⇒ with P = the pressure = 443.124 atm

⇒ V = the volume = 200.0 mL = 0.2 L

⇒ R is gas constant (0.08206 atm*L/mol*K)

⇒T = the  temperature = 300.0K

n =(443.124*0.2)/(0.08206*300)

n = 3.6 moles = total number of moles

<u>Step 6:</u> Calculate number of moles

For the reaction :2CO(g) + O₂(g) ⟶ 2CO₂(g)

For each mole of O2 we have 2 moles of CO, to produce 2 moles of CO2

Moles CO = (2 -2X) moles

Moles O2 = (2-X) moles

Moles CO2 = 2X

The total number of moles (4 -X)= 3.6 moles

Where X are moles that react

X = 0.400 moles

There will react 0.400 moles of oxygen.

Why are plant oils important in our diet?
Lesechka [4]
<span>Plant oil or also called as vegetable oils are considered as important part of our diet because it is the source of  energy in our diet. Foods that are cooked using vegetable oils produce more energy than to those foods that are cooked using other oil. Vegetable oils also contains saturated and unsaturated fats and oils.
Vegetable oil or plant oil are healthier compare to the other oil. It also lessen the unwanted and unhealthy fats of an oil and gives only proper health diet to our body.</span>

A light-year is the distance that light travels in one year. Please select the best answer from the choices provided T F
german

Answer:True

Explanation:

Light year is the unit of distance and not a unit of time.

Light year is used to measure astronomical distances.

It is defined as the distance which light travels in one year.

The distance which light travels in one year is around 9.46 trillion kilometers

Thus 1 light year = 9.46\times 10^9 km.

Thus the given statement that A light-year is the distance that light travels in one year is true.

Is blowing up a balloon a chemical change
Anarel [89]

Answer:

Yes

Explanation:

The combination of an acid and base causes a chemical reaction. The product is a gas, bubbles that are carbon dioxide. The carbon dioxide gas is trapped in the balloon and it inflates. The carbon dioxide gas molecules created a pressure by colliding with the sides of the balloon.
