which reagents are appropriate to carry out the conversion shown?
Answers
A reagent us a chemical substance applied in a chemical reaction to bring about a change in the chemical reaction process. The reagent that is appropriate to carry out the conversion is Ethanol (CH3CH2OH).
Organic Reactions are reactions taking place in organic compounds and they can take various forms such as electrophilic addition reaction or nucleophilic substitution reactions.
From the assumed diagram below, the reaction takes place in an unimolecular nucleophilic reaction SN1 mechanism in which a racemic mixture produce an organic compound and an enantiomer.
For the reaction to take place, the best organic reagent to us is known as ethanol (CH3CH2OH). This is because the organic reagent is a solvent that acts as a Nucleophile.
In the reaction, bromine (Br) is the leaving group, after it detaches from the racemic compound, it forms a carbonation in which the Ethanol CH3CH2OH attacks at the carbonation site.
Therefore, we can conclude that the Reagent necessary to carry out the conversion is Ethanol (CH3CH2OH)

To calculate half life, divide original value by 2.
1.
FOUR HALF LIVES = divide original value by 2, 4 times.

20 ÷ 2 = 10
10 ÷ 2 = 5
5 ÷ 2 = 2.5g
2. AFTER TEN DAYS (TWO HALF LIVES)
140 ÷ 2 = 70
70÷ 2 = 35g
AFTER TWENTY DAYS (FOUR HALF LIVES)

A mixture of hydrogen, nitrogen, and water vapor has a total pressure of 864 mmHg. The partial pressure of hydrogen is 220 mmHg and that of nitrogen is 410 mmHg. What is the partial pressure of water vapor?
Answers
Answer:
As per Dalton's law of Partial pressure,
The total pressure of a mixture of gases is equal to sum of partial pressure of individual components of the mixture.
So,P=P_H+P_N+P_WP=P
H
+P
N
+P
W
\implies 864\ mm=220\ mm+410\ mm+P_W\implies⟹864 mm=220 mm+410 mm+P
W
⟹ P_W=864-630=234P
W
=864−630=234 mm of Hg.
Explanation:
"The partial pressure of water vapor is 234 mm Hg."
What is partial pressure?
The force that a gas exerts is known as partial pressure. The total pressure of a mixture of gases is equal to the sum of their partial pressures.
Partial pressure can be calculated by using the formula: [tex]P_{Total} =P_{N} +P_{H} +P_{H}[/tex]
Puts the value of given data in above equation.
[tex]Px_{W} =864-410-220\\\\= 234 mm Hg[/tex]

If the Moon orbited Earth twice as fast, how many high tides would occur in one day?
Answers
Four high tides would occur in one day, if the moon orbited Earth twice as fast.
What are high tides?The tide when the water is at its greatest elevation.
At the moment, high tides occur twice a day. So if the moon orbits the earth twice as fast, high tides will occur twice as many, which means four times a day.
High tides occur 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high.
The best-known effect of the moon is its gravitational pull on Earth's oceans, which results in two high tides and two low tides every day.
But if the moon were half the distance from Earth as it is now, the tides would be eight times higher.

Answers
Answer:
Plate tetonics theory is the idea that different tectonic plates, are constantly moving and changing the surface of our Earth. They can move in three ways, convergent, divergent, and transform. Seafloor Spreading is like an example of divergent movement. When the plates diverge from each other it can create various changes such as creating a new sea floor. You can use seafloor spreading as an example of the plate tetonics theory.

How does density affect sinking and floating in water?
Answers
Answer:
Density is a measure of how heavy something is compared to its size.
If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.
Density is a characteristic property of a substance and doesn’t depend on the amount of substance.
Explanation:
If you compared the weight of wood and an equal amount, or volume, of water the sample of wood would weigh less than the sample of water. This means that wood is less dense than water. Since wood is less dense than water, wood floats in water, no matter how big or small the piece of wood is.
A student might want to know why a boat made out of steel can float when steel is more dense than water. This is not an easy question and requires a different approach than what students have seen so far. We do not necessarily recommend the following explanation for 5th graders but here is the idea:
An object floats when it displaces a volume of water that has a mass equal to the mass of the object. So if a material like steel is shaped into a boat and made larger and larger, it will displace more and more water. When it is large enough to displace a volume of water that has a mass equal to the mass of the boat, the boat will float.

15.24. Calcium hydroxide, also known as slaked lime, is used in industrial processes in which low concentrations of base are required. Only 0.16 g of Ca(OH)2 dissolves in 100 mL of water at 25°C. What is the concentration of hydroxide ions in 250 mL of a solution containing the maximum amount of dissolved calcium hydroxide?
Answers
The concentration of the hydroxide ions, OH¯ in 250 mL of the solution containing the maximum amount of dissolved calcium hydroxide is 0.01728 M
We'll begin by calculating the number of mole of in 0.16 g of Ca(OH)₂. This can be obtained as follow:
Mass of Ca(OH)₂ = 0.16 g
Molar mass of Ca(OH)₂ = 40 + 2[16 + 1] = 74 g/mol
Mole of Ca(OH)₂ =?Mole = mass / molar mass
Mole of Ca(OH)₂ = 0.16 / 74
Mole of Ca(OH)₂ = 0.00216 mole Next, we shall determine the molarity of the stock solution of Ca(OH)₂.Mole of Ca(OH)₂ = 0.00216 mole
Volume = 100 mL = 100 / 1000 = 0.1 L
Molarity of Ca(OH)₂ =?Molarity = mole / Volume
Molarity of Ca(OH)₂ = 0.00216 / 0.1
Molarity of Ca(OH)₂ = 0.0216 MNext, we shall determine the molarity of the diluted solution. This can be obtained as follow:Volume of stock solution (V₁) = 100 mL
Molarity of stock solution (M₁) = 0.0216 M
Volume of diluted solution (V₂) = 250 mL
Molarity of diluted solution (M₂) =?M₁V₁ = M₂V₂0.0216 × 100 = M₂ × 250
2.16 = M₂ × 250
Divide both side by 250
M₂ = 2.16 / 250
M₂ = 0.00864 MThus, the molarity of the diluted solution is 0.00864 M
Finally, we shall determine the concentration of the hydroxide ions, OH¯ in the diluted solution. This can be obtained as follow:Ca(OH)₂(aq) —> Ca²⁺(aq) + 2OH¯(aq)
From the balanced equation above,
1 mole of Ca(OH)₂ contains 2 moles of OH¯
Therefore,
0.00864 M Ca(OH)₂ will contain = 2 × 0.00864 = 0.01728 M OH¯
Thus, the concentration of the hydroxide ions, OH¯ in 250 mL of the solution containing the maximum amount of dissolved calcium hydroxide is 0.01728 M
