Answer:

0.26 L

Explanation:

Data given

Volume of acetic acid (HC₂H₃O₂) (V1) = ?

Molarity of acetic acid (HC₂H₃O₂) (M1) = 17.4 mol/L

Volume of acetic acid (HC₂H₃O₂) (V2) = 4.5 L

Molarity of acetic acid (HC₂H₃O₂) (M2) = 1.0 mol/L

Solution:

As we diluting the concentrated acetic acid (HC₂H₃O₂)

So, Dilution formula will be used

M1V1 = M2V2

Put values in above equation

17.4 mol/L x V1 = 1.0 mol/L x 4.5 L

Rearrange the above equation

V1 = 1.0 mol/L x 4.5 L / 17.4 mol/L

V1 = 4.5 mol / 17.4 mol/L

V1 = 0.26 L

So 0.26 L of acetic acid (HC₂H₃O₂) is required

24 grams of CH4 was added to the above reaction. Calculate the theoretical yield of CO2. A. 66 grams B. 33 grams c. 132 grams. D

Sonbull [250]

Answer:

Option A. 66 g

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

CH₄ + 2O₂ —> CO₂ + 2H₂O

Next, we shall determine the mass of CH₄ that reacted and the mass of CO₂ produced from the balanced equation. This is illustrated below:

Molar mass of CH₄ = 12 + (4×1)

= 12 + 4 = 16 g/mol

Mass of CH₄ from the balanced equation = 1 × 16 = 16 g

Molar mass of CO₂ = 12 + (16×2)

= 12 + 32 = 44 g/mol

Mass of CO₂ from the balanced equation = 1 × 44 = 44 g

SUMMARY:

From the balanced equation above,

16 g of CH₄ reacted to produce 44 g of CO₂.

Finally, we shall determine the theoretical yield of CO₂. this can be obtained as follow:

From the balanced equation above,

16 g of CH₄ reacted to produce 44 g of CO₂.

Therefore, 24 g of CH₄ will react to produce = (24 × 44) /16 = 66 g of CO₂.

Thus, the theoretical yield of CO₂ 66 g

How many atoms are in an oxygen molecule?

ZanzabumX [31]

Answer:

two atoms

Explanation:

In its stable molecular form, oxygen exists as two atoms and is written O2. to distinguish it from an atom of oxygen O, or ozone, a molecule of three oxygen atoms, O3. Even though each of these is all oxygen, combining atoms of the same element may give very different properties to the molecule.

The δs∘rxn for the reaction $2NO(g) + O_{2}$ → $2NO_{2} (g)$ will be -146 J/K.

Entropy would be a measurable physical characteristic and a scientific notion that is frequently connected to a condition of disorder, unpredictability, or uncertainty.

Entropy would be a measurement of the system's unpredictability or disorder. The entropy increases as randomness do. It has broad properties as well as a state function. It has the unit $JK^{-1} mol^{-1}$ .
