Which additional product balances the reaction H2SO4 + 2NaOH → Na2SO4 + ? 2H2O 2OH H2O2 H3O

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:

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.

Answer:

d) Oxygen molecules will spread through both jars because of the high molecular weight of oxygen.

Explanation:

Oxygen molecules will spread evenly throughout both jars because of weak intermolecular forces.

Intermolecular forces hold the molecules of matter together in a particular state of matter.

Gases have the weakest intermolecular forces between them. As such, the molecules of gases are isolated from each other and they move at very high velocities.

Due to weak intermolecular forces between the molecules of oxygen gas, when the valve between the two jars is opened, oxygen gas spreads evenly throughout the both jars.

What is the frequency of a photon that has a wavelength of 754 um? ​

Answer:

115.2ml of water should be added.

Explanation:

We start with 46.2ml of 1.396M sugar solution;

We want to end up with a 0.56M sugar solution;

Finding the number of moles in the sugar solution to begin with:

moles of sugar in solution initially = 46.2 × 1.396 = 64.4952

Vd = volume of desired solution (i.e. 0.56M solution)

w = volume of water added

Vd = (46.2 + w)

Using the mol = vol' × conc'n equation:

64.4952 = Vd × 0.56

Vd = 64.4952/0.56

Vd = 115.17

46.2 + w = 115.17

w = 115.17 - 46.2

w = 68.97ml

Explanation:

Is it right

Answer:

NaOH is the limiting reactant and MgCl2 is in excess.

Explanation:

let's calculate the mole of each reactant.

number of moles of MgCl2 = [tex]\frac{187}{1000} L* 0.103 mol / L =0.01926 mol\\[/tex]

number of moles of NaOH = [tex]\frac{33.58 }{1000}L * 0.839 mol/L =0.0282 mol[/tex]

as per the reaction , 1 mol of Magnesium choloride reacts with 2 moles of NaOH

hence 0.01926 needs 0.01926x2= 0.03852 moles of NaOH , but there are only 0.0282 moles of NaOH available .

The limiting reactant for the reaction between 187.0 mL solution of 0.103 M MgCl₂ and 33.58 mL solution of 0.839 M NaOH is NaOH

We'll begin by calculating the number of mole of MgCl₂ and NaOH present in the solution.

Volume = 187 mL = 187 / 1000 = 0.187 L

Molarity = 0.103 M

Mole = Molarity x Volume

Mole of MgCl₂ = 0.103 × 0.187

Volume = 33.58 mL = 33.58 / 1000 = 0.03358 L

Molarity = 0.839 M

Mole = Molarity x Volume

Mole of NaOH = 0.839 × 0.03358

Finally, we shall determine the limiting reactant. This can be obtained as follow:

MgCl₂ + 2NaOH —> Mg(OH)₂ + 2NaCl

From the balanced equation above,

2 moles of NaOH required 1 mole of MgCl₂.

Therefore, 0.028 mole of NaOH will require = [tex]\frac{0.0282}{2}\\[/tex] = 0.014 mole of MgCl₂

From the calculations made above, we can see that only 0.014 mole of MgCl₂ out of 0.019 mole reacted completely with 0.028 mole of NaOH.

Therefore, NaOH is the limiting reactant and MgCl₂ is the excess reactant.

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 potential and kinetic energy of a falling book is present. Kinetic energy is indeed the force driving motion, manifested in the motion of a particle, an object, or a collection of particles.

The correct answer is A

Kinetic energy is the term for the energy present in an object in motion. Examples of velocity include your movement as you walk down the street and the planet's rotation around the sun. The formula for kinetic energy is as follows: K.E. is equal to half of an object's mass times its square velocity, or m/v2.

The capacity of kinetic energy to perform work is perhaps its most significant quality. The force applied to that of an object when it is moving is referred to as work. This intimate relationship between work and energy makes them go together.
