Answer: A
Explanation:
The heat contained in the car was transferred to the car primarily by the process of radiation.
Radiation is the emission of electromagnetic wave energy that originates from a source and travels via a space medium with the speed of light. When it is sunny during the day, all life forms and inanimate objects are exposed to radiation. Since a car has metallic properties, it has the ability to store and contain the heat for a longer period of time through the process known as radiation.

what
your events made Gautam Buddha to
go in search of the truth?
Answer:
The Buddha (also known as Siddhartha Gotama or Siddhārtha Gautama[note 3] or Buddha Shakyamuni) was a philosopher, mendicant, meditator, spiritual teacher, and religious leader who lived in Ancient India (c. 5th to 4th century BCE).[5][6][7][note 4] He is revered as the founder of the world religion of Buddhism, and worshipped by most Buddhist schools as the Enlightened One who has transcended Karma and escaped the cycle of birth and rebirth.[8][9][10] He taught for around 45 years and built a large following, both monastic and lay.[11] His teaching is based on his insight into duḥkha (typically translated as "suffering") and the end of dukkha – the state called Nibbāna or Nirvana.
The Buddha was born into an aristocratic family in the Shakya clan but eventually renounced lay life. According to Buddhist tradition, after several years of mendicancy, meditation, and asceticism, he awakened to understand the mechanism which keeps people trapped in the cycle of rebirth. The Buddha then traveled throughout the Ganges plain teaching and building a religious community. The Buddha taught a middle way between sensual indulgence and the severe asceticism found in the Indian śramaṇa movement.[12] He taught a spiritual path that included ethical training and meditative practices such as jhana and mindfulness. The Buddha also critiqued the practices of Brahmin priests, such as animal sacrifice.
A couple of centuries after his death he came to be known by the title Buddha, which means "Awakened One" or "Enlightened One".[13] Gautama's teachings were compiled by the Buddhist community in the Suttas, which contain his discourses, and the Vinaya, his codes for monastic practice. These were passed down in Middle-Indo Aryan dialects through an oral tradition.[14][15] Later generations composed additional texts, such as systematic treatises known as Abhidharma, biographies of the Buddha, collections of stories about the Buddha's past lives known as Jataka tales, and additional discourses, i.e, the Mahayana sutras.

What mass of Cu(s) is electroplated by running 19.5 A of current through a Cu2 (aq) solution for 4.00 h
Answer:
92.46 g
Explanation:
The reaction is
[tex]Cu^{2+}+2e^-\rightarrow Cu[/tex]
I = Current = 19.5 A
t = 4 hours = [tex]4\times 60\times 60=14400\ \text{s}[/tex]
F = Faraday constant = 96485.33 C/mol
Molar mass of copper = 63.546 g/mol
Charge is given by
[tex]Q=It\\\Rightarrow Q=19.5\times 14400\\\Rightarrow Q=280800\ \text{C}[/tex]
Moles of electrons is given by
[tex]\dfrac{Q}{F}=\dfrac{280800}{96485.33}\\ =2.91\ \text{mol}[/tex]
Moles of copper is
[tex]\dfrac{1}{2}\times \dfrac{Q}{F}=\dfrac{1}{2}\times 2.91\\ =1.455\ \text{mol}[/tex]
Mass of copper would be
[tex]\text{Moles}\times \text{Molar mass of copper}=1.455\times 63.546\\ =92.46\ \text{g}[/tex]
The mass of copper electroplated is 92.46 g.
Under what conditions can a supersaturated solution be formed?
A- cool the solution back down to room temperature very carefully
B- cool the solution back down to room temperature haphazardly
C- leave the solution undisturbed as it is cooling
D- heat a solvent above room temperature
E- cool a solvent below room temperature
Answer:
E. Cool a solvent below room temperature
Explanation:
When a solution that has had more solute dissolved at a higher temperature is now cooled, it becomes supersaturated at the lower temperature. Because that supersaturated solution holds more solute than is stable at the lower temperature, crystals start to form.
To solve this we must be knowing each and every concept related to supersaturated solution. Therefore, the correct option is option E among all the given options.
What is supersaturated solution?The excess solute solution that the solvent can dissolve is known as a supersaturated solution. The substance that may dissolve in a solution, such as salts but not limited to salts, is referred to as a solution if we are unsure of what a solute or solvent is.
A solution becomes supersaturated at a lower temperature when it is cooled after having additional solute incorporated at a higher temperature. Crystals begin to form because the supersaturated solution contains more solute than would be stable just at lower temperature.
Therefore, the correct option is option E among all the given options.

At constant pressure for which of the reactions shown below should Delta H be greater than Delta E°?
1.2 SO2(g) + O2(g) - 2 SO3(g)
II. C5H12(9) + 8 O2(g) - 5 CO2(g) + 6 H20(1)
III. H2(g) + Br2(g) → 2 HBr(9),
IV. N204(9) - 2 NO2(g)
Answer: [tex]N_2O_4(g)\rightarrow 2NO_2(g)[/tex] has higher value of [tex]\Delta H[/tex] than [tex]\Delta E[/tex]
Explanation:
The realtion between enthalpy change and internal energy change is:
[tex]\Delta H=\Delta E+\Delta n_gRT[/tex]
where,
= enthalpy of the reaction
= internal energy of the reaction
[tex]\Delta n_g[/tex] = change in the gaseous moles of the reaction = Moles of product - Moles of reactant
R = gas constant
T = temperature
1. [tex]2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)[/tex]
[tex]\Delta n_g[/tex] = 2-3 = -1
2. [tex]C_5H_{12}(g)+8O_2(g)\rightarrow 5CO_2(g)+6H_2O(l)[/tex]
[tex]\Delta n_g[/tex] = 5-9 = -4
3. [tex]H_2(g)+Br_2(g)\rightarrow 2HBr(g)[/tex]
[tex]\Delta n_g[/tex] = 2-2 = 0
4. [tex]N_2O_4(g)\rightarrow 2NO_2(g)[/tex]
[tex]\Delta n_g[/tex] = 2-1 = 1
Thus reaction . [tex]N_2O_4(g)\rightarrow 2NO_2(g)[/tex] has higher value of [tex]\Delta H[/tex] than [tex]\Delta E[/tex]
At constant pressure the given reaction that shows ΔH would be greater than ΔE is;
IV); N₂0₄(g) → 2NO₂(g)
In chemistry, he meaning of ΔH and ΔE are;
- ΔH means the change in enthalpy, which is heat content.
- ΔE means the change in energy of a system.
Now, for a closed system the relationship between ΔH and ΔE is given by;
ΔH = ΔE + PΔV
where PΔV = ΔnRT
Thus; ΔH = ΔE + ΔnRT
where Δn = number of moles of product in the gaseous state - number of moles of reactants.
Thus, if Δn is negative, then ΔE would be greater than ΔH but if Δn is positive, then ΔH would be greater than ΔE
I) 2SO₂(g) + O₂(g) ⇒ 2SO₃(g)
number of moles of product = 2
number of moles of reactants = 2 + 1 = 3
Δn = 2 - 3
Δn = -1 and so ΔE would be greater than ΔH
II) C₅H₁₂(g) + 8O₂(g) ⇒ 5CO₂(g) + 6H₂0(l)
number of moles of product = 5 (6 is not used because water is in liquid and not gas)
number of moles of reactants = 8 + 1 = 9
Δn = 5 - 9
Δn = -4 and so ΔE would be greater than ΔH
III) H₂(g) + Br₂(g) → 2HBr(g)
number of moles of product = 2
number of moles of reactants = 1 + 1 = 2
Δn = 2 - 2
Δn = 0 and so ΔE would be equal to ΔH
IV) N₂0₄(g) → 2NO₂(g)
number of moles of product = 2
number of moles of reactants = 1
Δn = 2 - 1
Δn = +1 and so ΔH would be greater than ΔE

A student measures out exactly 0.0970 g of salicylic acid and carries out an aspirin synthesis using salicylic acid, acetic anhydride, heat, and an acid catalyst. Salicylic acid is the limiting reagent in this reaction, which yields 0.1030 g of aspirin. What is the percent yield for the reaction?
Answer: 106.19%
Explanation:
percent yield = actual/theo * 100%
our theoretical yield is the limiting reagent and then we have our actual given
.1030/.0970* 100% = 106.19%
The percent yield of prepared aspirin is 102.84%.
What is percent yield?Percent yield is defined as the ratio of actual yield to the theoretical yield multiplied by 100. If the actual and theoretical yield are same then the percent yield is 100%.If actual yield is less than the theoretical yield then the percent yield is less than 100%.Reason of this condition arising is the incompletion of reaction or loss of sample during recovery process.
In cases where percent yield is over 100% it indicates that more sample is recovered than the predicted amount.This condition arises when there are other simultaneous reactions taking place leading to the formation of product. It can also arise if there is incomplete removal of impurities from the sample .
By using the formula of percent yield , yield of aspirin is calculated as,
0.1030/0.1264 ×100=81.48%.
Thus, the percent yield of aspirin is 81.48%.
