This molecule undergoes a substitution reaction through an SN1 pathway when warmed and stirred with HBr. Draw the two substitution products of this reaction. Show the correct stereochemistry by using wedges and dashes at all chiral centers. In part two, select the term that correctly describes the relationship between the products.

Answer:

The similarity is that they both follow the laws of physics.

In both cases, the motion is opposed by the medium where the object presses through the medium and forces it to part and flow around the object. This creates friction.

If an object is smooth and pointed like a bomb, the friction is minimised. If it is rough with pockets or vertical flat surfaces, the friction is maximised. A parachute presents a round hollow cup face to the flow, maximising friction. This is due to a hole in the top of the parachute.

The difference is the power source. In the vertical direction it is generated by gravity, the force created by the planet. This force is opposed not only by friction but also the difference between the density of the object and the medium surrounding it. If there is a large difference then the acceleration will be large and a high percentage of g.

For example we have a density of 1000 kg/meters cubed and air has a density of 1 Kg per meters cubed, the difference is 999, so we fall at an acceleration of 999/1000 x g. minus the effects of friction.

In the horizontal direction, gravity still opposes the movement creating friction in the vertical direction such as dragging a heavy object on the floor behind you. Force needs to be created horizontally to oppose the friction and to create an acceleration. A balance is soon reached where the acceleration stops and the object is dragged at a constant velocity.

Answer:

48.8%

Explanation:

The reaction has a 1:1 mole ratio so;

Number of moles of benzoic acid reacted = mass/molar mass = 3.8 g/122.12 g/mol = 0.03 moles

So;

0.03 moles of methyl benzoate is formed in the reaction

Mass of methyl benzoate formed = 0.03 moles * 136.15 g/mol = 4.1 g

percent yield = actual yield/theoretical yield * 100/1

percent yield = 2.0 g/4.1 g * 100 = 48.8%

Answer:

2.49 M

Explanation:

Step 1: Given data

Step 2: Calculate the moles AlCl₃ (solute)

The molar mass of AlCl₃ is 133.34 g/mol.

150. g × 1 mol/133.34 g = 1.12 mol

Step 3: Calculate the molar concentration of AlCl₃

Molarity is equal to the moles of solute divided by the liters of solution.

M = 1.12 mol/0.450 L = 2.49 M

a. True

Explanation:

Hello there!

In this case, since the dose-response method is crucial concept in toxicology as it exhibits the result of exposures to toxic chemical compounds with changes in body functions or health, this statement is a. True , as this analysis is understood by means of the relationship -the higher the dose, the more severe the response-, and of course, it is based on observed data from controlled experiments in animal, human clinical, or cell studies, in the light of the determination of the toxicity of the analyzed chemical.

Answer:

Incorrect

Explanation:

Given that,

The mass of a boulder, m = 22 kg

We need to find the weight of the student in pounds.

We know that,

1 pound = 454 g

or

1 g = (1/454 pounds)

22 kg = 0.022  grams

So,

0.022 grams = [tex]\dfrac{0.022}{454}\ pounds[/tex]

= 0.000048 pounds

The student says the weight is 0.048 pounds. It means he was incorrect.

Answer:

A convex lens bends light rays inward, which results in the object being perceived as larger or closer.

Explanation:

The light ray refracted from an object may look different based on how they bends light and at what angle. Convex lens bends light inwards and the refracted light appear closer and bigger whereas, a concave lens makes light ray away and smaller.

Refraction is the optical phenomenon by which a light ray bends in its direction when passing from one medium to the other. For instance light ray bends when it pass from air to water or air to glass and vice versa.

The measure of bending of light in a medium  is called refractive index of that medium. Refraction makes the object appear to be closer sometimes such as in water when light bends in direction.

When light refracts from convex lens, the bending is inwards and the object is perceived to be closer and larger. Whereas, a concave lens make the bending outwards where the object appeared to be smaller and far.

Answer:

The answer to your question is given below

Explanation:

We'll begin by converting 500 cm³ to L. This can be obtained as follow:

1000 cm³ = 1 L

Therefore,

500 cm³ = 500 cm³× 1 L / 1000 cm³

500 cm³ = 0.5 L

Next, we shall determine the number of mole of Na₂CO₃ in the solution. This can be obtained as follow:

Volume = 0.5 L

Molarity = 2 M

Mole of Na₂CO₃ =?

Molarity = mole /Volume

2 = Mole of Na₂CO₃ / 0.5

Cross multiply

Mole of Na₂CO₃ = 2 × 0.5

Mole of Na₂CO₃ = 1 mole

Finally, we shall determine the mass of 1 mole of Na₂CO₃. This can be obtained as follow:

Mole of Na₂CO₃ = 1 mole

Molar mass of Na₂CO₃ = (23×2) + 12 + (16×3)

= 46 + 12 + 48

= 106 g/mol

Mass of Na₂CO₃ =?

Mass = mole × molar mass

Mass of Na₂CO₃ = 1 × 106

Mass of Na₂CO₃ = 106 g

Thus, to prepare the solution, weigh 106 g of Na₂CO₃ and dissolve in 500 cm³ (i.e 0.5 L) of water.

Answer:

0.012 mole of electron

Explanation:

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

Time (t) = 90.6 minutes

Current (I) = 213.8 mA

Number of mole of electrons =?

Next, we shall convert 90.6 mins to seconds. This can be obtained as follow:

1 min = 60 s

Therefore,

90.6 mins = 90.6 × 60

90.6 mins = 5436 s

Next, we shall convert 213.8 mA to A. This can be obtained as follow:

1000 mA = 1 A

Therefore,

213.8 mA = 213.8 mA × 1 A / 1000 mA

213.8 mA = 0.2138 A

Next, we shall determine the quantity of electricity used in the process. This can be obtained as follow:

Time (t) = 5436 s

Current (I) = 0.2138 A

Quantity of electricity (Q) =?

Q = it

Q = 0.2138 × 5436

Q = 1162.2168 C

Next, the equation for the reaction.

Au⁺ + e —> Au

From the balanced equation above,

1 mole of electron was transferred.

Recall:

1 faraday = 96500 C = 1 e

Thus,

96500 C of electricity is needed to transfer 1 mole of electron.

Finally, we shall determine the number of mole electrons transferred by the application of 1162.2168 C of electricity. This can be obtained as follow:

96500 C of electricity is needed to transfer 1 mole of electron.

Therefore,

1162.2168 C of electricity will transfer = 1162.2168 / 96500 = 0.012 mole of electron

Thus, 0.012 mole of electron was transferred in the process.

Following are the calculation to the moles of electrons that transferred in the process:

Answer:

25.155 gram

Explanation:

HCl(aq.) + NaOH(aq.) ⇒ NaCl + H2O

According the above equation equal number of moles of reactant are producing same number of moles of products.

Now, no. mole of HCl = 15.7/(1+35.5) = 0.43 moles

no. of moles of NaOH = 27/(23+16+1) = 0.675 moles

Since  the  amount  of  sodium  hydroxide  exceeds  the  amount  of  hydrochloric  acid,  the maximum amount of each substance participating in the reaction is HClν ν  0.43 moles .Therefore, the maximum amount of NaCl  that can be produced is as follow

= (23+35.5)×0.43 = 25.155 gram
