I think the correct answer is the third option. Particulates are solid or liquid particles that settle after being dispersed in a gas. They are also termed as particle pollution or PM. It is a mixture of very small particles and liquid droplets which includes acids of nitrates and sulfates, organic substance, metals and dust particles.

A mixture of CO (g) and excess O2(g) is placed in a 1.0 L reaction vessel at 100.0C and a total pressure of 1.50 atm. The CO is

umka2103 [35]

Answer:

Partial pressure of of CO₂ in the product mixture is 0,20atm

Explanation:

The balance equation is:

2CO(g) + O₂(g) → 2CO₂(g)

Total pressure of CO(g) and O₂(g) gases before reaction at 100,0°C and 1,0L is 1,50 atm. You can say:

X₁ + Y₁ = 1,50atm (1)

Where X₁ is initial partial pressure CO and Y₁ is initial partial pressure of O₂

After reaction partial pressures are:

X₂ = X₁ - 2n = 0; 2n = X₁

Y₂ = Y₁ - n

Z₂ = 2n

Where Z₂ is final partial pressure of CO₂

After reaction pressure at 100,0°C and 1,0L is 1,40 atm, that means:

1,40 atm = (Y₂ + Z₂)

1,40 atm = Y₁ - n + 2n

1,40atm = Y₁ + n

1,40 atm = Y₁ + X₁/2 (2)

Replacing (1) in (2)

1,40 atm = 1,50atm - X₁ + X₁/2

-0,10 atm = - X₁/2

0,20 atm = X₁.

As 2n = X₁; 2n = Z₂ = 0,20 atm

I hope it helps!

Ibuprofen, a well-known non-steroidal anti-inflammatory drug, has chirality. Only the S enantiomer has anti-inflammatory activit

lorasvet [3.4K]

Answer:

See image attached

Explanation:

Ibuprofen is a chiral compound. 'Chiral' means that it has the ability to rotate plane polarised light owing to the presence of an asymmetrically substituted carbon atom. There are two known stereoisomers of the compound; the S- stereoisomer and the R-stereoisomer. The both are shown using wedge and dash perspectives in the image attached.

Only the S- stereoisomer is active as a drug. The R-stereoisomer is gradually converted into the S-stereoisomer in the body. The drug may also be given as a racemic mixture.

Consider the reaction:

devlian [24]

Gosh, I love chem!

[H2O]/t should be 0.085M/s

this is because of the coefficients in front of H2S and H2O being the same.

the significance of this answer is that the H2S disappears at the same rate H2O appears.

Answer:

The greatest acceleration when the unbalanced force is applied will be experienced in :

A) The box with a mass of 2 kg

Explanation:

According to second law of motion the external unbalanced force is directly proportional to rate of change of momentum.

F = (Final momentum - initial momentum)/time

Force is equal to the product of mass and acceleration

F = m x a

Here a= acceleration

m = mass of the object

If Force is constant then acceleration is inversely proportional to mass

$a =\frac{F}{m}$

A) The box with a mass of 2kg

F = 8 N

$a =\frac{8}{2}$

a = 4 m/s2

B) The box with the mass of 4kg

$a =\frac{8}{4}$

a = 2 m/s2

C) The box with a mass of 6kg

$a =\frac{8}{6}$

a = 1.33 m/s2

D) The box with a mass of 8kg

$a =\frac{8}{8}$

a = 1 m/s2
