What is nucleophilic substitution reaction?
One nucleophile substitutes another in a family of organic reactions known as nucleophilic substitution reactions.
SN1 stands for nucleophilic substitution reaction. Leaving group, a nucleophile, electrophile and a solvent are present. The first step is the slowest because a bond is being broken to form carbocation by the attack of hydrogen ion from the HI acid. Then carbocation rearrangement takes place. Attack of iodide ion to form product 2-Iodo-2,3-dimethylbutane.
Therefore, the major organic product of the reaction shown is 2-Iodo-2,3-dimethylbutane.

Incorporate the meaning distance and displacement in the poem tagalog or English not necessarily the exact definition halimbawa: Itong mga dayuhan bago nakarating sa ating Bayan ay naglakbay ng ilang milya mula kanluran papuntang timog silangan
Answer:
Displacement.
Explanation:
The example i.e. these foreigners before arriving in our Town traveled several miles from west to southeast represents displacement not distance because in this example direction of the objects are given. We know that distance is a scalar quantity which is expressed from its magnitude only while on the other hand, displacement is a vector quantity which can be fully explained through magnitude as well as direction of the object. in this example, west to southeast represents direction of the objects so we can say that it refers to the displacement.

A 3.4 g sample of an unknown monoprotic organic acid composed of C,H, and O is burned in air to produce 8.58 grams of carbon dioxide and 1.50 grams of water vapor. It was also determined that 279 mL of 0.1 M KOH was needed to titrate the acid completely.
Answer:
[tex]C_7H_6O_2[/tex]
Explanation:
Hello there!
In this case, we can divide the problem in three stages: (1) determine the empirical formula with the combustion analysis, (2) compute the molar mass of acid via the moles of the acid in the neutralization and (3) determine the molecular formula.
(1) In this case, since 8.58 g of carbon dioxide are released, we can first compute the moles of carbon in the compound:
[tex]n_C=8.58gCO_2*\frac{1molCO_2}{44.01gCO_2}*\frac{1molC}{1molCO_2}=0.195molC[/tex]
And the moles of hydrogen due to the produced 1.50 grams of water:
[tex]n_H=1.50gH_2O*\frac{1molH_2O}{18.02gH_2O}*\frac{2molH}{1molH_2O} =0.166molH[/tex]
Next, to compute the mass and moles of oxygen, we need to use the initial 3.4 g of the acid:
[tex]m_O=3.4g-0.195molC*\frac{12.01gC}{1molC}-0.166molH*\frac{1.01gH}{1molH} =0.89gO\\\\n_O=0.89gO*\frac{1molO}{16.0gO}=0.0556molO[/tex]
Thus, the subscripts in the empirical formula are:
[tex]C=\frac{0.195}{0.0556}=3.5 \\\\H=\frac{0.166}{0.0556}=3\\\\O=\frac{0.0556}{0.0556}=1\\\\C_7H_6O_2[/tex]
As they cannot be fractions.
(2) In this case, since the acid is monoprotic, we can compute the moles by multiplying the concentration and volume of KOH:
[tex]n_{KOH}=0.279L*0.1mol/L\\\\n_{KOH}=0.0279mol[/tex]
Which are equal to the moles of the acid:
[tex]n_{acid}=0.0279mol[/tex]
And the molar mass:
[tex]MM_{acid}=\frac{3.4g}{0.0279mol} =121.86g/mol[/tex]
(3) Finally, since the molar mass of the empirical formula is:
7*12.01 + 6*1.01 + 2*16.00 = 122.13 g/mol
Thus, since the ratio of molar masses is 122.86/122.13 = 1, we infer that the empirical formula equals the molecular one:
[tex]C_7H_6O_2[/tex]

Explanation:
Hello there!
In this case, for the reaction by which water is decomposed to molecular hydrogen and oxygen:
[tex]H_2O\rightarrow H_2+O_2[/tex]
It is necessary to perform the inspection balance process since there is a dissimilar number of atoms of oxygen on both sides; therefore, by putting a 2 on water we balance oxygen:
[tex]2H_2O\rightarrow H_2+O_2[/tex]
But now, there are four hydrogens on the left; therefore, we put a 2 on hydrogen to finally balance it:
[tex]2H_2O\rightarrow 2H_2+O_2[/tex]
And obviously, the coefficient in oxygen is an unwritten 1.

Which layer of the sun is shown extending into space in the picture above?
Answer:
Corona
Explanation:
The outermost layer of the sun's atmosphere is called the corona, meaning “crown.” The corona is formed of thin wisps of gas that extend outward into space for millions of miles. It is much less bright than the photosphere, so we can only see it if the rest of the sun is blotted out, for example during a solar eclipse.

Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given atoms}}{\text {avogadro's number}}[/tex]
1. [tex]\text{Number of moles of Cl}==\frac{2.393\times 10^{24}}{6.023\times 10^{23}}=3.973moles[/tex]
1 mol of Cl weighs = 35.5 g
Thus 3.973 mol of Cl weighs = [tex]\frac{35.5}{1}\times 3.973=140.9g[/tex]
2. [tex]\text{Number of moles of O}==\frac{2.393\times 10^{24}}{6.023\times 10^{23}}=3.973moles[/tex]
1 mol of O weighs = 16 g
Thus 3.973 mol of O weighs = [tex]\frac{16}{1}\times 3.973=63.58g[/tex]
Why is it necessary to know the temperature of the reactants and the products of a reaction in order to determine change in the Gibbs free energy of the reaction
Answer:
Free Energy (G) can either increase or decrease for a reaction when the temperature increases. It depends on the entropy (S) change. The change in a quantity is represented by the Greek letter delta. ... Hence, when the temperature increases the numeric value of the free energy becomes larger.
Explanation:
The change in Gibbs free energy (ΔG) of a chemical reaction depends on the initial and final states of the reactants and products, as well as on the temperature and pressure conditions of the reaction.
What is Gibb's free energy?The Gibbs free energy of a reaction tells us whether a reaction is spontaneous or not under given conditions, with negative ΔG values indicating a spontaneous reaction and positive ΔG values indicating a non-spontaneous reaction.
The temperature of the reactants and products is important in determining the Gibbs free energy change because the Gibbs free energy change is related to the enthalpy change (ΔH) and the entropy change (ΔS) of the reaction through the equation:
ΔG = ΔH - TΔS
where T is the temperature in Kelvin.
Thus, the temperature of the reactants and products must be known in order to calculate the Gibbs free energy change of a reaction accurately.

At a certain temperature 3.24 moles of co2 gas at 2.15atm takes up a volume of 35.28 what is the temperature in celsius
Answer:
The temperature is 12.35 C.
Explanation:
An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
P * V = n * R * T
In this case:
P= 2.15 atmV= 35.28 Ln= 3.24 molesR= 0.082 [tex]\frac{atm*L}{mol*K}[/tex]T= ?Replacing:
2.15 atm* 35.28 L= 3.24 moles* 0.082[tex]\frac{atm*L}{mol*K}[/tex] * T
Solving:
[tex]T=\frac{2.15 atm* 35.28 L}{3.24 moles* 0.082\frac{atm*L}{mol*K}}[/tex]
T=285.5 K= 12.35 C (being 273.15 K= 0 C)
The temperature is 12.35 C.
The relation between the moles, volume, temperature, and pressure is given by the ideal gas equation. The temperature of a gas is 12.35 celsius.
What is the ideal gas law?The ideal gas law is the hypothetical gas law that depicts the relation between pressure, volume, moles of the compound, and the temperature of the gas.
The ideal gas equation is given as,
[tex]\rm PV = nRT[/tex]
Given,
Pressure (P) = 2.15 atm
Volume (V) = 35.28 L
Number of moles (n) = 3.24 mol
Gas constant (R) = 0.082
Temperature (T) = ?
Substituting values in the above equation, the temperature is calculated as:
[tex]\begin{aligned} \rm T &= \rm \dfrac{PV}{nR}\\\\&= \dfrac{2.15\times 35.28}{3.24 \times 0.082}\\\\&= 286.23 \;\rm K\end{aligned}[/tex]
Therefore, 12.35 degrees Celsius is the temperature of the gas.

In the Neighborhood
Ahn vigorously scrubbed windows, a tedious necessity for her family's new Vietnamese restaurant. They had turned the building from homely to gorgeous, but everything had to be absolutely perfect: unique decorations, skillful employees, and fabulous traditional food. Then customers would adore the place, making the business a success.
Ahn shifted her vision to look outside the restaurant as a girl about her age, with abundant red hair, strolled up the street. Ahn’s family had recently moved to this neighborhood, so she had few friends.
The girl paused to study the sign announcing their opening and then looked directly at Ahn with a friendly smile. Ahn smiled back shyly and lifted a hand, accidentally waving with the cleaning cloth. The girl laughed at her amusement and waved back in acknowledgment.
Ahn hesitated, not accustomed to initiating friendship, but she felt courageous, so on a whim she opened the door. "Hello," she said, adding the first thing that entered her head, "do you like Vietnamese food?"
"I don't know, but I like to try new things,” the girl remarked, and then she introduced herself as Gabriela.
Ahn could not think of additional conversation until she had a sudden idea. "Please wait here," she requested, "and I'll be right back." She ran into the adjoining kitchen and explained her idea to her father. He was sympathetic, so seconds later Ahn presented a small package to Gabriela. "Some Vietnamese candy for you to try,” she explained. “If you enjoy it, I hope you'll return to the restaurant sometime, or even visit after school when I'll be here preparing for the dinner service."
"Excellent, I'll see you around soon.” Gabriela headed down the street, glancing back with a cheerful wave. Ahn spent the remainder of the afternoon hoping Gabriela really would return and not think Ahn’s gift was weird.
The following day, Ahn assembled bouquets of artificial flowers, orchids that would never wilt. She was admiring her accomplishment when she heard unexpected tapping and turned to see Gabriela beckoning to her with a plate covered with transparent plastic wrap. Ahn grinned with enthusiasm and opened the door with a cordial greeting.
Gabriela presented the plate and said, "I brought biscuits made from my grandmother's recipe to thank you for the delicious candy.”
"Come in, and we can have some biscuits right now," Ahn stammered, happy inside.
Gabriela entered and rotated to scan the room with its picturesque landscape mural. "Thanks, they really are wonderful, and I'm fascinated to see your restaurant."
As they snacked on the treats, Ahn fumbled for conversation and considered an offer. "Are you good with vocabulary?” she inquired. "I intend to design a publicity pamphlet for the restaurant, and I could use some assistance."
"Certainly!" Gabriela said, adding, "I'm delighted you moved into the neighborhood and thrilled I have a new friend."
Ahn grinned, now positive that the restaurant would make a wondrous impression on the community, that customers would be plentiful, and that she was going to enjoy life here immensely
