While in Europe, if you drive 125 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per lite

r and your car's gas mileage is 40.0 mi/gal ? Assume that 1euro=1.26dollars.

You would spend <em>$71.32</em> per week on gas.

<em>Step 1</em>. Convert <em>weeks to days </em>

Time = 1 wk × (7 days/1 wk) = 7 days

<em>Step 2</em>. Calculate the <em>distance</em> travelled

Distance = 7days × 125 km/day = 875 km

<em>Step 3</em>. Convert <em>kilometres to miles </em>

Distance = 875 km × (1 mi/1.609 km) = 543.8 mi

<em>Step 4</em>. Calculate the <em>gallons of gas </em>

<em>V</em> = 543.8 mi × (1 gal/40.0 mi) = 13.60 gal

<em>Step 5</em>. Convert <em>gallons to litres</em>

<em>V</em> = 13.60 US gal × (3.785 L/1 US gal) = 51.46 L

<em>Step 6</em>. Calculate the <em>cost of the gas</em>

Cost = 51.46 L × (€1.10/1 L) = €56.60

<em>Step 7</em>. Convert <em>euros to dollars</em>

Cost = €56.60 × ($1.26/€1) = <em>$71.32 </em>

Answer:

FeCl3 is the limiting reactant

O2 is in excess

Theoretical yield Cl2 = 9.84 grams

The % yield is 96.5 %

Explanation:

Step 1: Data given

Mass of FeCl3 = 15.0 grams

Moles O2 = 4.0 moles

Mass of Cl2 produced = 9.5 grams

Step 2: The balanced equation

4FeCl3 + 3O2 → 2Fe2O3 + 6Cl2

Step 3: Calculate moles FeCl3

Moles FeCl3 = mass FeCl3 / molar mass FeCl3

Moles FeCl3 = 15.0 grams / 162.2 g/mol

Moles FeCl3 = 0.0925 moles

Step 4: Calculate limiting reactant

FeCl3 is the limiting reactant. Because we have way more (more than ratio 3:4) moles O2 than FeCl3. It will completely be consumed (0.0925 moles). O2 is in excess. There will react = 0.069375 moles O2

There will remain 4.0 - 0.069375 = 3.930625 moles

Step 5: Calculate moles Cl2

For 4 moles FeCl3 we need 3 moles O2 to produce 2 moles Fe2O3 and 6 moles Cl2

For 0.0925 moles FeCl3 moles we'll have 6/4 * 0.0925 = 0.13875 moles Cl2.

Step 6: Calculate mass Cl2

Mass Cl2 = moles * molar mass

Mass Cl2 = 0.13875 moles * 70.9 g/mol

Mass Cl2 = 9.84 grams

Step 7: Calculate % yield

% yield = (actual yield / theoretical yield) * 100%

% yield = (9.5 grams / 9.84 grams ) * 100%

% yield = 96.5 %

The % yield is 96.5 %

Q= mcΔT
1623 = 33.69g x c x (110.8 - 29.4)
1623 = 2742.366 g•°C x c

NNADVOKAT [17]

Answer:

The question is not complete, the complete question should be "Lipids vesicles are formed containing pure water. If these vesicles are transferred to a solution that contains a rather high concentration of solutes, the solution outside the vesicle is said to be Hypertonic. True or False"

The answer is True

Explanation:

This is because  it contains greater concentration of solutes on the outside of the cell than the increase.

In other words hypertonic solutions have more concentrate of solutions on the outside than the inside.

Calculate the energy of an electron in the n = 2 level of a hydrogen atom.
ANEK [815]

Answer: The energy of an electron in the n = 2 level of a hydrogen atom is 3.40 eV.

Explanation:

Given: n = 2

The relation between energy and n^{th} orbit of an atom is as follows.

E = - \frac{13.6}{n^{2}} eV

Substitute the values into above formula as follows.

E = - \frac{13.6}{n^{2}} eV\\= - \frac{13.6}{(2)^{2}}\\= - 3.40 eV

The negative sign indicates that energy is being released.

Thus, we can conclude that the energy of an electron in the n = 2 level of a hydrogen atom is 3.40 eV.
