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.

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%.

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%.

Californians consume the most turkey per capita of any state, while not being one of the top five. It's Missouri. It comes in at five. Minnesota is the state that produces the most turkeys, followed by North Carolina, Arkansas, and Virginia.

Turkey, or the Republic of Turkey, is a transcontinental nation with the majority of its territory in Western Asia's Anatolia Peninsula and a tiny section in Southeast Europe's Balkan Peninsula.

The official name of Turkey is now Türkiye. The United Nations has officially accepted the adjustment requested by the Turkish government that the nation be referred to by its Turkish name.

Turkey is well-known for a variety of both oriental and European aspects, including the magnificent Hagia Sophia and traditional Turkish tea. Additionally, well-known are its carpets, hammams, bazaars, travel hotspots like Cappadocia and Istanbul, and sweets like baklava and Turkish delight.

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

The correct formula : BeSO₄

Chemical formula shows the composition number of the constituent atoms

Polyatomic ion consists of 2 or more ions

The equal charge of the two ions will cancel each other out, while the different charges of the two ions will be crossed each other

Be²⁺ (monatomic ion) has a positive charge of +2, while SO₄²⁻ (polyatomic ion) has a negative -2 charge, so that the two charges with the same magnitude but with different charges cancel each other out so that the compound form is BeSO4

Answer:

The correct answer is 10.939 mol ≅ 10.94 mol

Explanation:

According to Avogadro's gases law, the number of moles of an ideal gas (n) at constant pressure and temperature, is directly proportional to the volume (V).

For the initial gas (1), we have:

n₁= 1.59 mol

V₁= 641 mL= 0.641 L

For the final gas (2), we have:

V₂: 4.41 L

The relation between 1 and 2 is given by:

n₁/V₁ = n₂/V₂

We calculate n₂ as follows:

n₂= (n₁/V₁) x V₂ = (1.59 mol/0.641 L) x 4.41 L = 10.939 mol ≅ 10.94 mol

The number of moles is 10.94 mol.

The calculation is as follows:

The following formula should be used:

[tex]n_1\div V_1 = n_2\div V_2\\\\n_2= (n_2\div V_1) \times V_2\\\\ = (1.59 mol\div 0.641 L) \times 4.41 L[/tex]

= 10.939 mol

= 10.94 mol

Therefore we can conclude that the number of moles is 10.94 mol.

Percent yield is the compare of the amount of product obtained from a reaction with the amount you calculated

General formula:

Percent yield = (Actual yield / theoretical yield )x 100%
