The theory of what an atom looks like has evolved over time. From the ancient Greeks, to Dalton, to Rutherford—no idea was exact

ly the same. However, as more information is gathered, new ideas can build on the old. Sometimes new ideas can completely replace the old ones. Even today, there may be new advances that have changed our understanding of the atom that are not reflected in this course.
Answer one of the following prompts to begin your discussion:

You claim that the atomic model should not be continually changed. What reasoning would you give someone to help them understand your claim?
You claim that a new atomic model should always build on an old one. What reasoning would you give someone to help them understand your claim?
You claim that a new atomic model should completely replace an old one. What reasoning would you give someone to help them understand your claim?
You claim that the continuous evolution of the atomic model is beneficial, but you think it should be a mix of the old and the new. What reasoning would you give someone to help them understand your claim?

To being my discussion, I claim that a new atomic model should always build on an old one with the following reasons of mine. That is option B.

<h3>What is an atomic model?</h3>

An atomic model is a model that describes how the interior of an atom looks like. This first atomic model was developed by William Thomson.

To start my discussion, I claim that a new atomic model should always build on an old one with the following reasons of mine:

  • The modern scientists exploited the ideas of the ancient scientists to arrive at a better atomic model.

  • This method is proven the the works of Bohr in the Bohr atomic model which relied on quantum mechanics, built upon the Rutherford model to explain the orbits of electrons.

Answer:

15. Velocity = 3 X 10^8

     Distance = 1580 m

time = distance / velocity

<em>t = 1580 / 3 * 10^8</em>

<em>t =  1580 * 10^-8 / 3 </em>

<em>t = 158 * 10^-7/3</em>

<u>t = 5.26 * 10^-8 seconds  </u>

16. Converting the distance to 'm'

Given distance (in miles), multiplying by 1.609 to convert to  km and also multiplying by 1000 to convert to 'm'

s= 4.8 * 1.609 * 10^7 * 1000

v = 3 * 10^8

t =  4.8 * 1609  * 10^7 / 3 * 10^8

t = 1.6 * 1609 * 10^-1

t = 2574.4 * 10^ -1

t = 2.5744 * 10^-4 s

17. Mass in 1 tsp of medicine = 5 mL at a density of 25 mg/mL

Mass in 1 tsp of medicine = 5 * 25 = 125 mg

Mass prescribed by the doctor  = 375 mg

Number of table spoons required = Mass prescribed / Mass in 1 tsp

N = 375/125 = 3 table spoons of the medicine

18. Density of medicine = 400g/ 5mL = 80g / mL

Medicine required = 1500 g

Volume of medicine required = Medicine Required / Density of medicine

Volume = 1500 / 80 = 18.75 mL of medicine is required

Hence, the volume of the suspension should be at least 18.75 mL

19. Volume of 10 drops = 1 mL

Volume of 5 drops = 1/2 mL

The faucet is leaking 5 drops or 1/2 mL water per minute

Number of minutes in a day = 60 * 24  = 1440 minutes in a day

Water leaked in 1440 minutes = 1440 * 1/2 = 720

0.720 L (720 mL) Water leaked from the faucet in a day

14. A cylinder at 48.0 atm pressure and 17.0°C releases 35.0 mL of carbon dioxide gas into a
grin007 [14]

59.78175 kPa is the pressure inside the container when a cylinder at 48.0 atm pressure and 17.0°C releases 35.0 mL of carbon dioxide gas into a 4.00 L container at 24.0°C.

<h3>What is an ideal gas equation?</h3>

An ideal gas equation states the relationship between the moles of the substance, temperature, pressure, and volume. The ideal gas equation is given as, PV=nRT

Given data:

P_1=48.0 atm

V_1=3T_1=17.0°C

P_2=?

V_2=4.00 L

T_2=24.0°C

\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}

\frac{48.0 atm X 35.0 mL}{17.0} = \frac{P_2X 4000 ml L}{24.0}

P_2= 0.59 atm = 59.78175 kPa

Hence, 59.78175 kPa is the pressure inside the container when a cylinder at 48.0 atm pressure and 17.0°C releases 35.0 mL of carbon dioxide gas into a 4.00 L container at 24.0°C.
