Considering the principles of KMT, which scenario would result in an increase of particles effective collisions at STP None of the above None of the above In a balloon In a balloon A container with large volume A container with large volume A container with small volume

Answers

Answer 1

Answer:

A container with small volume

Explanation:

The question is obviously incomplete because the image attachments are missing.

However, it is necessary to note that, the effective collisions depends on the volume of the gas.

The lesser the gas volume, the greater the effective collision between particles at STP.

Hence from the KMT, the scenario having the least volume of gas will have the greatest magnitude of effective collisions.

Where exactly is an orbital? I understand they are a volume where we expect to find electrons 90% of the time but I don't understand where their shapes are and fit on an atom, and the different forms of orbitals confuse me a little. Can someone explain me where they are with the help of an image? Pardon me if my question isn't very clear

Answers

Answer:

95% of the time (or any other percentage you choose), the electron will be found within a fairly easily defined region of space quite close to the nucleus. Such a region of space is called an orbital. You can think of an orbital as being the region of space in which the electron lives

Boyd takes additional measurements of the mass of product formed in a reaction. He uses a balance that has smaller graduations than the first balance he used.
What is Boyd most likely trying to change?

Options:
He is trying to increase his accuracy but not his precision.
He is trying to increase his precision but not his accuracy.
He is trying to decrease his precision and increase his accuracy.
He is trying to increase his precision and decrease his accuracy.

Answers

Answer:

The correct option is A: "He is trying to increase his accuracy but not his precision"

Explanation:

Accuracy of measurement is when the value of the measurement is close to the actual value of that measurement while precision is when the experiment is repeated using the same instrument but obtaining different values.

When Boyd changed the weighing balance in his experiment to a smaller one, the smaller weighing balance has better accuracy (smaller graduations) than the initially used one because the smaller weighing balance will provide a value close to the actual value of the mass of the product. If he had, however, repeated the experiment without changing the weighing balance, he would have sought to increase his precision.

From the description above, it can be said that Boyd was trying to increase his accuracy but not his precision

The correct option is A: "He is trying to increase his accuracy but not his precision"

Write the balanced symbol equation for the electrolysis of aluminium oxide to produce aluminium, and the reduction of iron oxide with carbon to produce iron.


Then use that to calculate the atom economy for each.

Answers

Answer:

Electrolysis of Al₂O₃: 4Al³⁺ (s) + 6O²⁺ (g) → 4Al (s) + 3O₂ (g)

Reduction of Elemental Fe: 2Fe₂O₃ (s) + 3C (s) → 4Fe (s) + 3CO₂ (g)

Atom Economy for Electrolysis of Al₂O₃: 52.9227%

Atom Economy for Reduction of Fe₂O₃: 62.8534%

Explanation:

Step 1: Define Compounds

Aluminum Oxide - Al₂O₃

Iron Oxide - Fe₂O₃

Step 2: RxN

Al₂O₃ (s) → Al (s) + O₂ (g)

Fe₂O₃ (s) + C (s) → Fe (s) + CO₂ (g)

Step 3: Balance RxN

2Al₂O₃ (s) → 4Al (s) + 3O₂ (g)

We need the same number of O on both sides (6 is the LCM)We will also need to balance the number of Al on both sides due to the change of O (4 reactant/product)

This is ONLY the decomposition reaction for Aluminum oxide, NOT the electrolysis.

2Fe₂O₃ (s) + 3C (s) → 4Fe (s) + 3CO₂ (g)

We need the same number of O on both sides (6 is the LCM)We will also need to balance the number of Fe on both sides due to the change of O (4 reactant/product)We will also need to balance the number of C on both sides due to the change of O (3 reactant/product)

This is the final single-replacement reaction for the reduction of Iron Oxide to Iron.

Step 4: Electrolysis of Al₂O₃

We will have to use oxidation-reduction reactions (half-reactions). Let's break up the reaction into it's elements.

Al³⁺ + ? → Al

To make the ion Al³⁺ turn into its neutral atom, we will need to add 3e⁻ to balance the half reaction

Al³⁺ + 3e⁻ → Al

O²⁻ → O₂ + ?

Oxygen is a diatomic element, and in it's natural state is bonded to itself. We need to balance the half reaction

2O²⁻ → O₂ + ?

We need to figure out how much electrons the ion O²⁻ loses to turn into its neutral atom. We see that we will need to lose 4e⁻

2O²⁻ → O₂ + 4e⁻

Our half reactions:

Al³⁺ + 3e⁻ → Al

2O²⁻ → O₂ + 4e⁻

We now need balance the entire half reaction. Our LCM is 12

4 (Al³⁺ + 3e⁻ → Al) = 4Al³⁺ + 12e⁻ → 4Al

3 (2O²⁻ → O₂ + 4e⁻) = 6O²⁻ → 3O₂ + 12e⁻

Add the 2 half reactions

4Al³⁺ + 12e⁻ + 6O²⁺ → 4Al + 3O₂ + 12e⁻

Cancel out spectator ions/e⁻ to get our final half reaction

4Al³⁺ (s) + 6O²⁺ (g) → 4Al (s) + 3O₂ (g)

Step 5: Atom Economy

According to GCSE and my own deciphering, your equation for Atom Economy is essentially calculating for something similar to percent yield (but not quite).

[tex]Atom \hspace{3} Economy \hspace{3} = \hspace{3} \frac{Molar \hspace{3} Mass \hspace{3} of \hspace{3} Product}{Molar \hspace{3} Mass \hspace{3} of \hspace{3} All \hspace{3} Reactants} \cdot 100 \%[/tex]

4Al³⁺ (s) + 6O²⁺ (g) → 4Al (s) + 3O₂ (g)

Molar Mass of Al - 26.98 g/mol

Molar Mass of O - 16.00 g/mol

Reactants: 4(26.98 g/mol) + 6(16.00 g/mol) = 203.92 g/mol

Products (Al as end product): 4(26.98 g/mol) = 107.92 g/mol

[tex]Atom \hspace{3} Economy \hspace{3} = \hspace{3} \frac{107.92 \hspace{3} g/mol}{203.92 \hspace{3} g/mol} \cdot 100 \%=52.9227 \%[/tex]

2Fe₂O₃ (s) + 3C (s) → 4Fe (s) + 3CO₂ (g)

Molar Mass of Fe - 55.85 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of C - 12.01 g/mol

Reactants: 4(55.85 g/mol) + 6(16.00 g/mol) + 3(12.01 g/mol) = 355.43 g/mol

Products (Fe as end product): 4(55.85 g/mol) = 223.4 g/mol

[tex]Atom \hspace{3} Economy \hspace{3} = \hspace{3} \frac{223.4 \hspace{3} g/mol}{355.43 \hspace{3} g/mol} \cdot 100 \%=62.8534\%[/tex]

Ou are subliming camphor and you note that pure camphor is condensing nicely on the cold finger. You check on the process several minutes later and you see that the amount of camphor on the cold finger has not changed appreciably since the last time you looked at it. However, there is still plenty of impure camphor left at the bottom of the flask. What do you suppose is the reason and what do you need to do.

Answers

Answer:

The reaction is endothermic

Increase temperature of the flask

Explanation:

Sublimation is a phenomenon in which a substance changes directly from solid to gas,without passing through the liquid phase.

Camphor is a sublime substance. The sublimation of camphor is an endothermic reaction. This implies that energy is absorbed in the process.

For an endothermic reaction, the equilibrium position is shifted towards the right hand side by increasing the temperature of the system. Hence, if the flask is heated, more camphor will condense within a shorter time interval.

A guava with a mass of 0.200 kg has a weight of 1.96N

HOW TO CALCULATE WEIGHT:

The weight of an object is its mass with respect to gravity. That is, the weight of an object, which is a force measured in Newton (N) can be calculated as follows:

F = mass (m) × acceleration due to gravity (a)

The mass of the guava in this question is given as 0.200kg, hence, the weight is calculated as follows:

F = 0.200g × 9.8m/s²

F = 1.96N

Hence, a guava with a mass of 0.200 kg has a weight of 1.96N.

A 1.00-L flask is filled with 1.00 moles of H2 and 2.00 moles of I2. The value of the equilibrium constant for the reaction of hydrogen and iodine reacting to form hydrogen iodide is 50.5 under the given conditions. What are the equilibrium concentrations of H2 , I2 , and HI in moles/L? H2 (g) + I2 (g) ⇌ 2HI(g)

Answers

Answer:

[tex] C_{H_{2}} = 0.07 M [/tex]

[tex] C_{I_{2}} = 1.07 M [/tex]

[tex] C_{HI} = 1.86 M [/tex]

Explanation:

The reaction is:

H₂(g) + I₂(g) ⇄ 2HI(g)

Initially, we have the following concentrations of H₂ and I₂:

[tex] C_{H_{2}} = \frac{n}{V} = \frac{1 mol}{1.00 L} = 1 mol/L [/tex]

[tex] C_{I_{2}} = \frac{n}{V} = \frac{2 mol}{1.00 L} = 2 mol/L [/tex]

Then, in the equilibrium we have:

H₂(g) + I₂(g) ⇄ 2HI(g)

1-x       2-x         2x

[tex] Kc = \frac{[HI]^{2}}{[H_{2}][I_{2}]} = \frac{(2x)^{2}}{(1-x)(2-x)} [/tex]

[tex] 50.5*(1-x)(2-x) - (2x)^{2} = 0 [/tex]

By solving the above equation for x we have:

x₁ = 2.32 and x₂= 0.93

Hence, the concentrations of H₂, I₂ and HI are:

[tex] C_{H_{2}} = 1-x = 1 - 0.93 M = 0.07 M [/tex]

[tex] C_{I_{2}} = 2-x =  2 - 0.93 M = 1.07 M [/tex]

[tex] C_{HI} = 2*x = 2*0.93 M = 1.86 M [/tex]

The index of refraction for plastic, when speed of light in plastic is 1.5.

How do we calculate refraction index?

Refraction index of any substance will be calculated by using the below equation:

n = c/v, where

c = speed of light in vaccum = 3×10⁸ m/s

v = speed of light in plastic = 2×10⁸ m/sec

On putting values in the above equation, we get

n = 3×10⁸ / 2×10⁸ = 1.5

Hence the refractive index of plastic is 1.5.
