Carbon monoxide (CO) is a poisonous gas because it binds very strongly to the oxygen carrier hemoglobin in blood. A concentratio

velikii [3]

Answer: The amount of CO that is occupied in the room is $1.98\times 10^3L$

Explanation:

We are given:

Concentration of CO = $8.00\times 10^2ppm=800pm$ by volume

This means that $800\mu L\text{ or }800\times 10^{-6}$ of CO is present in 1 L of blood

To calculate the volume of cuboid, we use the equation:

$V=lbh$

where,

V = volume of cuboid

l = length of cuboid = 10.99 m

b = breadth of cuboid = 18.97 m

h = height of cuboid = 11.89 m

$V=10.99\times 18.97\times 11.89=2478.83m^3$

Converting this into liters, by using conversion factor:

$1m^3=1000L$

So, $2478.83m^3=2.479\times 10^6L$

Applying unitary method:

In 1 L of blood, the amount of CO present is $800\times 10^{-6}$

So, in $2.479\times 10^6L$ of blood, the amount of CO present will be = $\frac{800\times 10^{-6}}{1}\times 2.479\times 10^{6}=1983.2L=1.98\times 10^3L$

Hence, the amount of CO that is occupied in the room is $1.98\times 10^3L$

50 + 25 pts + brainliest other brainly answers are incorrect color luster and taste are correct but i need 1 or 2 more Some phys

r-ruslan [8.4K]

Answers and Explanations:

Physical properties are characteristics of substances that can be seen without a change in its chemical composition.

Here, physical properties are:

- density

- color

- luster

- taste

- abundance

- source

I'm not completely sure what you mean by "source", but I'm going to assume you mean the substance's origin found in nature.

In the following chemical reaction, which element is shown to be violating the law of conservation of mass? C3H8 + 4O2 -> 3CO

AlexFokin [52]

Checking if it is balanced:

C
3 3

H
8 4*2 = 8

O
8 3*2 + 4 = 6 + 4 = 10
8 10

Only O is not balanced.

So O is violating the law. Option C.

C. O

Phenol and benzoic acid are both weak acids that are solublein

stealth61 [152]

Answer:

Se explanation below

Explanation:

Here we will use the technique of extraction taking advantange of the different solubilities of Phenol and and Benzoic Acid in the NaOH and and NaHCO₃ solvents (In reality their anions). Notice that phenol does not dissolve in the weak base NaHCO₃ so we can have the solution of phenol and benzoic acid in ether and proceed to extract with this weak base, the phenol will remain in solution in the organic ether solution and the sodium benzoate will go into the water layer.

We then will repeat the extraction procedure to separate the phenol from the organic layer by using NaOH instead.

Benzoic Acid /

Phenol/ Ether ⇒Extract w/ ⇒ Organic Layer = Phenol/Ether

10 % NaHCO₃ Aqueous Layer = Sodium Benzoate

Sodium benzoate ⇒ 10 % HCl to precipitate Benzoic Acid

Filter Precipitate benzoic Acid ⇒ Recrystallize benzoic Acid

Phenol / Ether Extract w/ Organic Layer = Eher

10 % NaOH Aqueous Layer =

Sodium Phenolate

Sodium Phenolate ⇒ 10% HCl to precipitate Phenol Filter Precipitate Phenol ⇒ Recrystallize Phenol

Bond type of aluminum sulfide

pashok25 [27]

Aluminium= semimetal (positive charge)
Sulphur= nonmetalic (negative charge)
Al2S3
Its ionic bond coz aluminium and sulphur are making bond w opposite charges.
Hope it helps!!
