Osmium metal, the densest element, has a density of 22.6 g/mL, while hydrogen, the least dense element, has a density of 8.99 e-5 g/mL. Calculate the volume occupied by 1.00 g of each element. How many times more dense is osmium than hydrogen?

Answers

Answer:

1. Volume of osmium = 0.044 mL

2. Volume of Hydrogen = 11123.47 mL

3. Osmium is 251390 times denser than hydrogen

Explanation:

From the question given above, the following data were obtained:

Density of osmium = 22.6 g/mL

Density of Hydrogen = 8.99×10¯⁵ g/mL

Mass of osmium = 1 g

Mass of Hydrogen = 1 g

1. Determination of the Volume of osmium.

Density of osmium = 22.6 g/mL

Mass of osmium = 1 g

Volume of osmium =?

Density = mass /volume

22.6 = 1 / volume

Cross multiply

22.6 × volume = 1

Divide both side by 22.6

Volume = 1 / 22.6

Volume of osmium = 0.044 mL

2. Determination of the Volume of Hydrogen.

Density of osmium = 8.99×10¯⁵ g/mL

Mass of osmium = 1 g

Volume of osmium =?

Density = mass /volume

8.99×10¯⁵ = 1 / volume

Cross multiply

8.99×10¯⁵ × volume = 1

Divide both side by 8.99×10¯⁵

Volume = 1 / 8.99×10¯⁵

Volume of Hydrogen = 11123.47 mL

3. Determination of the number of times osmium is denser than hydrogen.

Density of osmium (Dₒ) = 22.6 g/mL

Density of Hydrogen (Dₕ) = 8.99×10¯⁵ g/mL

Dₒ / Dₕ = 22.6 / 8.99×10¯⁵

Dₒ / Dₕ = 251390

Cross multiply

Dₒ = 251390 × Dₕ

Thus, osmium is 251390 times denser than hydrogen.

O B. The sun and a comet are bright and made up entirely of gas.
O C. The sun is at the center of the solar system, and the comet orbits around it.
O D. The sun is very small in size compared to a comet.

Answers

Answer:

c

Explanation:

The sun is at the center of the solar system, and the comet orbits around it.

The sun is at the center of the solar system, and the comet orbits around it. Therefore, option C is correct. Comets are orbiting around sun through the elliptical orbit.

What are comets ?

Comets are tiny spatial objects that are composed of ice, dust and gases. Comets go around the sun in a highly elliptical orbit. They can spend hundreds and thousands of years out in the depths of the solar system before they return to sun at their perihelion.

Like all orbiting bodies, comets follow Kepler's Laws - the closer they are to the Sun, the faster they move. While a comet  is at a great distance from the Sun, its exists as a dirty snowball several kilometers across.

But as it comes closer to the sun, the warming of its surface causes its materials to melt and vaporize producing the comet's characteristic tail. Comet tails can be as long as the distance between the Earth and the Sun. Hence, option  C is correct.

Unknown:

Number of moles  = ?

Solution:

To solve this problem we need to first find the molar mass of the given compound.

 Molar mass of C₂H₆ = 2(12) + 6(1)  = 30g/mol

So;

 Number of moles  = [tex]\frac{mass}{molar mass}[/tex]  

Number of moles  = [tex]\frac{13}{30}[/tex]    = 0.43mole

.
The empirical formula of a substance has the smallest ratio between the elements its composed of.
Here, we got the carbon to hydrogen ratio as

. So, we need to find the greatest common factor between the two numbers.

10=2*5

22=2*11

As you can see here, the greatest common factor between the two numbers is

Answer:

The number of passengers that the Embraer E170 could carry if its fuselage was made of steel  is 39 passengers

Explanation:

The given parameters of the cylinder representing the fuselage are;

The length of the cylinder, l = 30.0 meters

The width of the cylinder, w = 2.5 meters

The thickness of the cylinder, t = 2.5 mm = 0.0025 meters

The volume of the metal required to make the fuselage cylinder, V = (π·w²/4 - π·(w - 2·t)²/4) × l

Therefore, by substituting the known values, we have;

V = (π × 2.5²/4 - π×(2.5 - 2×0.0025)²/4) × 30 = 0.58845957392

The volume of the metal required to make the fuselage cylinder, V≈ 0.58846m³

The given density of steel = 7.87 g/cm³ = 7870 kg/m³

The given density of aluminum = 2.70 g/cm³ = 2,700 kg/m³

Mass = Density × Volume

The mass of the fuselage made with steel = The given density of steel × The volume of the metal required to make the fuselage cylinder

∴ The mass of the fuselage made with steel = 7870 × 0.58846 ≈ 4631.18

The mass of the fuselage made with steel ≈ 4631.18 kg

Similarly, the mass of the fuselage made with aluminum = 2,700 × 0.58846 ≈ 1588.84

The mass of the fuselage made with aluminum ≈ 1588.84 kg

The total mass the Embraer E170 could carry = The mass of the fuselage made with aluminum + The mass of the 78 passengers

The average mass of each passenger = 79 kg

∴ The total mass the Embraer E170 could carry ≈ 1588.84 + 78 × 79 = 7750.84

The total mass the Embraer E170 could carry ≈ 7750.84 kg

The extra mass the Embraer E170 could carry when made of steel = (The total mass the Embraer E170 can carry) - (The mass of the fuselage made with steel)

∴ The extra mass the Embraer E170 could carry when made of steel = 7750.84 - 4631.18 = 3119.36

The extra mass the Embraer E170 could carry when made of steel ≈ 3119.36 kg

The number of passengers the Embraer E170 could carry when made of steel  = (The extra mass the Embraer E170 could carry when made of steel)/(The average mass of one passenger)

∴ The number of passengers the Embraer E170 could carry if its fuselage was made of steel  = 3119.36 kg/(79 kg/passenger) ≈ 39.489 passengers

The number of passengers that the Embraer E170 could carry if its fuselage was made of steel  ≈ 39 passengers (we round down when counting people which are whole quantities)

The sucrose molecule is a large and complex molecule built of carbon, hydrogen, and oxygen. How many sucrose

molecules are in 0.5 moles of sucrose?

Answers

Answer:

There are 3.01x10²³ molecules of sucrose

Explanation:

In order to calculate the number of molecules of any atom or compound, we need to use the Avogadro number which is 6.02x10²³. This number could represent atoms or molecules of any mole of compound or atom.

In other words, 1 mole of a certain atom or compound has 6.02x10²³ molecules or atoms.

we have 0.5 moles of sucrose, all we just need to do is a simple rule of 3:

If 1 mole contains 6.02x10²³ molecules

then 0.5 moles will contain:

n° molecules = 0.5 * 6.02x10²³ / 1

n° molecules = 3.01x10²³ molecules of sucrose

TiCl4 + H2O TiO2 + HCl

a. How many moles of H2O are needed to react with 6.50 moles of TiCl4? (13.0)

b. How many moles of HCl are formed when 8.44 moles of TiCl4 react? (33.8)

Answers

Explanation:

The reaction given is;

TiCl4 + H2O --> TiO2 + HCl

The reaction is not balanced, upon balancing it is given as;

TiCl4 + 2H2O → TiO2 + 4HCl  

a. How many moles of H2O are needed to react with 6.50 moles of TiCl4?

From the reaction;

1 mol of TiCl4 requires 2 mol of H2O

6.50 mol of TiCl4 would require x mol of H2O

1 = 2

6.5 = x

x = 6.5 * 2 / 1 = 13.0 mol

b. How many moles of HCl are formed when 8.44 moles of TiCl4 react?

From the equation of the reaction;

1 mol of TiCl4 reacts to form 4 mol of HCl

8.44 mol of TiCl4 reacts to form x mol of HCl

1 = 4

8.44 = x

x = 8.44 * 4 / 1 = 33.76 mol

A sample of oxygen gas has a volume of 150 mL when its pressure is 0.587 atm at 155 K. If the pressure and temperature are increased to STP, what will the new gas volume be?​

Answers

Answer:

V₂ = 155.17 mL

Explanation:

Given data:

Initial volume = 150 mL

Initial pressure = 0.587 atm

Initial temperature = 155 K

Final temperature = 273.15 K

Final volume = ?

Final pressure = 1 atm

Formula:  

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

Solution:

V₂ = P₁V₁ T₂/ T₁ P₂  

V₂ = 0.587 atm × 150 mL × 273.15 K / 155 K × 1 atm

V₂ = 24050.86 atm .mL. K / 155 K.atm

V₂ = 155.17 mL

how molecules react to an increase in temperature.

Answers

Answer:

An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).
