If 24 g rams of ozone, 03, was collected how many moles were collected?

Answers

Answer 1

Hey there!

Molar mass of O3 = 47.9982 g/mol

therefore:

1 mole O₃ ---------------------  47.9982 g

moles O₃ ---------------------- 24 g

moles O₃ = 24 x 1 /  47.9982

moles O₃ = 24 / 47.9982

moles O₃ = 0.500 moles

Hope this helps!

If 0.484J of heat is added to 0.1372g of water, how much will the temperature increase?

0.263 °C
0.927 °c
0.843 °C
0.460 °C

Answers

Answer:

ΔT = 0.843 °C

Explanation:

Given data:

Heat added = 0.484 J

Mass of water = 0.1372 g

Temperature increase = ΔT = ?

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Specific heat capacity of water is 4.184 j/g.°C

Now we will put the values in formula.

0.484 j = 0.1372 g × 4.184 j/g.°C× ΔT

0.484 j = 0.574j/°C× ΔT

ΔT = 0.484 j / 0.574j/°C

ΔT = 0.843 °C

How can electronegativity be used to explain the reaction we see in terms of the numbers and types of bonded being formed in lithium?

Answers

Explanation:

Lithium is an electropositive element that readily loses electrons.

Oxygen is electronegative and it will readily accept electrons.

 Due to this significant electronegativity differences between the two species they form electrovalent or ionic bonds between them.

  2atoms of Li lose two electrons:

      Li  →  Li²⁺ + e⁻

             Lithium isoelectronic with helium

 For oxygen;

      O + 2e⁻   →  O²⁻

                          Oxygen is isoelectronic with Neon

Two ions of the lithium combines with the oxygen to form the bond;

                   4Li + O₂  →  2Li₂O

The electrostatic attraction between the two ions forms the ionic bond

1. What is volume displacement? Why would you use this method?

2. What is density? What happens to things that are denser? What happens if they are less dense?

Answers

Answer:

1. The volume of displaced fluid is equivalent to the volume of an object fully immersed in a fluid or to that fraction of the volume below the surface of an object partially submerged in a liquid. The weight of the displaced portion of the fluid is equivalent to the magnitude of the buoyant force.

Why would you use this method?

So it can be used to accurately measure the volume of the human body and other oddly shaped objects by measuring the volume of fluid displaced when the object is submerged.

2. Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.

What happens to things that are denser?

Students should realize that if an object weighs more than an equal volume of water, it is more dense and will sink, and if it weighs less than an equal volume of water, it is less dense and will float.

What happens if they are less dense?

The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.

what is the density of aluminum if you have a piece of aluminum that is 10.5cm x 10.5cm x 0.1cm and has a mass of 29.8 grams?​

Answers

Answer:

2.7g/cm³

Explanation:

Given parameters:

Dimension of the aluminum  = 10.5cm x 10.5cm x 0.1cm

Mass of the aluminum  = 29.8g

Unknown:

Density  = ?

Solution:

Density of a substance is its mass per unit volume;

  Mathematically;

       Density  = [tex]\frac{mass}{volume}[/tex]

Volume of the aluminum  = 10.5cm x 10.5cm x 0.1cm = 11.025cm³

  So, insert the parameters and solve;

  Density  = [tex]\frac{29.8}{11.025}[/tex]   = 2.7g/cm³

1 You place a 28.95-g piece of gold in a 10-ml graduated cylinder. The level of the water rises 1.50 mL. What is the density of gold?​

Answers

Answer:

What mass of silver will raise the level of the water in the graduated cylinder 1.50 mL? (Ans) 28.95 g / 1.50 mL = 19.3 g/mL (The gold's density)

19.3 gm/ml³ is the density of gold  .

What do you mean by the density of the substance?

Density, mass of a unit volume of a material substance. Density of a substance tells how close the particles of a substance are packed.

The formula for density is D = M/V, where d is density, M is mass, and V is volume.

Density is commonly expressed in units of grams per cubic centimeter.

The SI unit of density is kilogram per cubic meter (kg/m3).

It is also represented  in the c g s unit of grams per cubic centimeter (g/cm3).

To calculate density of gold (here):

Given,

Mass of gold=28.95 gm

Volume of water=1.50 mL

Density=?

Density =Mass/Volume

Density=28.95/1.50

Density=19.3 gm/ml³

Hence, 19.3 gm/ml³ is the density of gold .

Isopentyl acetate is the molecule largely responsible for the aroma and taste of bananas. It is made up of carbon, hydrogen, and oxygen. Combustion of a 3.256-g sample of isopentyl acetate produces 7.706 g CO2 and 3.156 g H2O. Using these results, what is the correct empirical formula for isopentyl acetate?

Answers

Answer:

Explanation:

7.706 g of CO₂ will contain 12 x 7.706 / 44 g of C

= 2.1 g of C .

This will be contained in 3.256 g of isopentyl acetate

3.156 g of H₂O will contain 2 x 3.156 / 18 g of H

= .351 g of H

This will be contained in 3.256 g of isopentyl acetate

Rest will be oxygen

amount of oxygen in 3.256 g of isopentyl acetate

= 3.256 - ( 2.1 + .351 )

= .805 g

ratio of C , H , O in isopentyl acetate

= 2.1 g : .351 g : .805 g

2.1 / 12 : .351 / 1 : 0.805 / 16 ratio of moles

= .175 : .351 : .05  ratio of moles

= 3.5 : 7.02: 1

= 7 : 14 : 2

The diagram below shows what happens to an atom of uranium-235 when bombarded by a neutron. Which isotope is represented by X in the diagram?

Answers

Answer:

X represents barium - 141 nucleus.

Written as: (141, 56) Ba

Explanation:

In nuclear fission reaction, due to the fact that the process produces more neutrons, a nuclear chain reaction can possibly occurr. Now, a chain reaction is a one whereby the material that begins the reaction will also be one of the products and it can start another reaction.

Now, for the nuclear chain reaction for the fission of uranium-235, its nucleus absorbs a neutron after which it splits into a krypton - 92 nucleus and a barium - 141 nucleus. Thereafter it releases three more neutrons.

Thus, X is the image represents barium - 141 nucleus.

when it is 60, the degree is 10°

when it is 90, the degree is 15° and so on...

Answer:

T₂ = 695.33 K

Explanation:

Given data:

Initial volume = 150 mL

Initial temperature = 25°C (25+273 = 298 K)

Final temperature = ?

Final volume = 350 mL

Solution:

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

T₂ = V₂T₁ /V₁

T₂ = 350 mL × 298 K / 150 mL

T₂ = 104300 mL.K / 150 mL

T₂ = 695.33 K
