One of the compounds used to increase the octane rating of gasoline is toluene (right). Suppose 20.0 mL of toluene (d = 0.867 g/

mL) is consumed when a sample of gasoline burns in air.
(a) How many grams of oxygen are needed for complete combustion of the toluene?

<u>54.12g </u>of oxygen are needed for complete combustion of the toluene.

<h3>What is toluene?</h3>

Toluene is a transparent, colourless liquid that, when heated to room temperature, turns into a vapour. A strong or sweet smell coming from toluene vapour indicates exposure.

Typically, toluene is combined with other solvents, chemicals, and substances like paint pigments. Many sectors and workplaces utilise products that may include toluene, such as paint, metal cleaners, and adhesives. Toluene is also present in fuels such as gasoline. Workers exposed to toluene may work with paints, varnishes, shellac, nail polish, glues & adhesives, rust inhibitors, or printing inks.

Toluene exposure in the workplace can occur by inhalation, skin contact, splashing into the eyes, and ingestion. Workers who are exposed to this kind of thing may become ill right away or experience repercussions later. Exposures to toluene have been investigated in auto repair, construction, nail salons, and printing facilities.

What volume of 12M HCI is needed to prepare 250<br> of 0.20M HCI?
Alchen [17]

Answer: 4.2

Explanation:

M_{A}V_{A}=M_{B}V_{B}\\(12)V_{A}=(250)(0.20)\\V_{A}=\frac{(250)(0.20)}{12}=\boxed{4.2}

The osmotic pressure of a saturated solution of strontium sulfate at 25 ∘C∘C is 21 torrtorr. Part A What is the solubility produ
USPshnik [31]

Answer

solubility product = 3.18x 10^-7

Explanation:

We were given the pressure in torr then we need to convert to atm for consistency, ten we have

21torr/760= 0.0276315789 atm

21 Torr = .0276315789 atm

P = i M S T

M = P / iRT

Where p is osmotic pressure

T= temperature= 25C+ 273= 298K

for XY vanthoff factor i = 2

S = 0.0821 L-atm / mol K

M = .0276315789 atm / (2)(0.0821 L atm / K mole)(298 K)

M = 0.000564698046 mol/liters

solubility= 0.000564698046 mol/liters

Ksp = [X+][Y-]

Ksp = X^2

Ksp = [Sr^+2] * [SO4^-2]

Ksp = X^2

Ksp = (0.000564698046)^2

Ksp = 3.18883883 × 10-7

Ksp = 3.18x 10^-7

solubility product = 3.18x 10^-7

Therefore, the solubility product of this salt at 25 ∘C∘C is 3.18x 10^-7

What are the correct answers to these questions?
Anni [7]
The answer to both is D. Here's why:
For the first, whenever motion changes in a magnetic field, it causes electrons to move. Electricity, which is needed to power a lightbulb, is just a term for movement of these electrons. Electrons aren't created, they're always there in the wire. It's just that the permanent magnet gets them to move, which produces electricity.
For the second, it is very similar to the first. A magnet won't cause any electric current at rest, it always requires motion in order to produce an electric current. If you keep both of those in mind, it should help in the future. Hope this helps!
