2. Based on what you know about waves and light, do you think that light can be
modeled as a wave? Explain why or why not.

Answers

Answer 1

Answer:

Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM - you have light. ... So, Maxwell's equations do say that light is a wave.

3. A sample of neon gas has a volume of 1.2 L at 28.5°C. What will the volume be at 125°C it the
pressure remains constant?

Answers

Answer:

1.58L

Explanation:

Given parameters:

Initial volume  = 1.2L

Initial temperature  = 28.5°C  = 28.5 + 273  = 301.5K

Final temperature  = 125°C  = 125 + 273  = 398K

Unknown:

New volume  = ?

Solution:

Volume and temperature relationship is resolved using the Charles's law.

The law states that "the volume of a fixed mass of a gas varies directly as its absolute temperature if the the pressure is constant".

So;

       [tex]\frac{V1}{T1}[/tex]    = [tex]\frac{V2}{T2}[/tex]  

V1 is the initial volume

T1 is the initial temperature

V2 is the new volume

T2 is the new temperature

             [tex]\frac{1.2}{301.5}[/tex]    = [tex]\frac{V2}{398}[/tex]    

              301.5V2  = 477.6

                       V2  = 1.58L

Answers

Answer:

2.86L

Explanation:

Given parameters:

V1  = 2.1L

T1  = 200°C  = 200 + 273  = 473K

T 2  = 370°C  = 370 + 273  = 643K

Unknown:

V2  = ?

Solution:

Since pressure is constant, we apply the Charles's law;

           [tex]\frac{V1}{T1}[/tex]   =  [tex]\frac{V2}{T2}[/tex]  

V is volume

T is the temperature

1 is the initial state

2 is the new state

                [tex]\frac{2.1}{473}[/tex]    = [tex]\frac{V2}{643}[/tex]  

                 V2  = 2.86L

The complete combustion of acetic acid, HC2H3O2(I) to form water, H2O(I), and CO2(g), at constant pressure releases 871.7 kJ of heat per mol of acetic acid.
Write a balanced thermochemical equation if 5.0g of acetic acid will be used in the reaction.
HC2H3O2(I) + O2 --- H2O(I) + CO2(g) H= -871.7 kJ

Answers

Answer:

HC2H3O2(I) + O2(g) ---> H2O(I) + CO2(g) ΔH= -72.35 kJ

Explanation:

We know that 5.0 g of acetic acid will contain, 5.0g/60 g/mol = 0.083 moles of acetic acid

Now from the reaction equation;

1 mole of acetic acid evolved -871.7 KJ of heat

0.083 moles of acetic acid will evolve 0.083 * -871.7 = -72.35 KJ

For 5.0 g of acetic acid, we can write;

HC2H3O2(I) + O2(g) ---> H2O(I) + CO2(g) ΔH= -72.35 kJ

How to calculate the number of molecules in 18g of H2O

Answers

We, know molecular mass of water is, M = 16 g/mol .

Given mass of water, m = 18 g.

We know, number of moles is given by :

[tex]n = \dfrac{18\ g}{16 \ g/mol}\\\\n = 1.125\ moles[/tex]

Now, 1 mole of any compound contains 6.022 × 10²³ molecules.

So, number of moles in 1.125 moles of water is 1.125 × 6.022 × 10²³ =

6.77 × 10²³ molecules.

Hence, this is the required solution.

over the opening. The bottle with the balloon is then placed in very hot water and the balloon inflated. Why
did the balloon inflate?

Answers

Answer:

hot air rises and expanded the balloon

Explanation:

thats it.

The hot air rises and expanded the ballon. This is as the air in the bottle cools down, the molecules of the air slow down and take up less space because they move closer together. The air then moves out of the balloon and back into the bottle, causing the balloon to deflate.

Answers

Answer:

4

Explanation:

The following equation, which depicts the combustion of propane, is given in this question as follows:

C3H8 + 02 → CO2 + H2O

However, this equation is not yet BALANCED because the number of atoms of each element is not the same on the reactant and product side. To balance the equation, we make use of COEFFICIENT to ensure that the number of atoms of each element on both side correlates.

The balanced equation is as follows:

C3H8 + 502 → 3CO2 + 4H2O

Therefore, the coefficient for water (H2O) after balancing the equation is 4.

The study of chemicals is called chemistry.

The correct answer is D.

The equation is not yet BALANCED because the number of atoms of each element is not the same on the reactant and product sides.

To balance the equation, we make use of COEFFICIENT to ensure that the number of atoms of each element on both sides correlates.

After balancing the equation is as follows:

[tex]C_3H_8 + 50_2 → 3CO_2 + 4H_2O[/tex]

Hence, the correct answer is 4 which shows the balanced water.

Predicting the future based solely on the position of the planets is an example of pseudoscience.

Pseudoscience is a body of knowledge that is not based on the scientific method but on some unverifiable/unprovable claims.

Predictions about the future can only be valid if it is based on the scientific method, not just about the position of the planet. The scientific method involves observation, hypothesis formulation, testing of the hypothesis through repeatable experiments, and arriving at conclusion.

The proton number of barium (Ba) is 56. It is in Group II of the periidic table how many electrons would you expect a barium atom to contain in its outer energy level?

Answers

Answer:

A barium atom would be expected to contain 2 electrons in its outer energy level.

Explanation:

The columns of the periodic table are called groups. There are eighteen groups, numbered from 1 to 18.

The elements of each group have the same number of electrons in their last atomic shell, which is why they have similar chemical properties, because the chemical properties of chemical elements are strongly related to the electrons located in the last atomic shell.

That is, in a group, the chemical properties are very similar, because all the elements of the group have the same number of electrons in their last or last shells.

A barium atom would be expected to contain 2 electrons in its outer energy level.

Assuming constant pressure, what should the new volume of the balloon be?

Round your answer to one decimal place.

Answers

Answer:

1125.75 cm³

Explanation:

We are given;

Initial volume; V1 = 673 cm³

Initial temperature; T1 = 275 K

Final temperature; T2 = 460 K

From Charles law, we can find the new volume from;

V1/T1 = V2/T2

V2 = (V1 × T2)/T1

V2 = (673 × 460)/275

V2 = 1125.75 cm³

Explanation:

The Aufbau's principle describes that electrons fill lower energy levels first before occupying higher energy levels.

It states that "sublevels with with lower energies are filled up before those with higher energies".

An object has a volume of 825 cm3 and a density of 13.6 g/cm3. Find its
mass

Answers

answer: 11,200 g

step by step explanation:

D= M/V
M= DV
M= (13.6 g/cm^3) (825cm^3)
M= 11,200 g

The mass of an object is the product of its volume and density. The mass of a the object with a volume of 825 cm³ and a density of 13.6 g/cm³ is 11220 g.

What is density ?

Density of substance is the measure of its mass per unit volume. It describes how closely its particles are packed. Density depends on the bond type, temperature and pressure.

Volume of the object is the space occupied by its particles. Volume can be expressed in L, ml, cm³, dm³ etc. Only solids and liquids has a definite volume and the volume of gases is that of the container.

Give that, volume of the object = 825  cm³

density =  13.6 g/cm³

Mass = volume × density

m = 825  cm³ ×  13.6 g/cm³ = 11220 g

Therefore, the mass of the object is 11220 g.
