Answers

Answer 1

The energy released is approximately 2.22 * 10^17 J, which is the correct option among the given choices.

This is a question about nuclear fusion, which is the process of combining two atomic nuclei to form a heavier nucleus. During this process, a significant amount of energy is released. The equation given in the question is for the fusion of two deuterium nuclei (^2H) to form helium-3 (^3He) and a neutron (^1n): ^2H + ^2H → ^3He + ^1n
3.00 metric tons = 3.00 x 1000 kg = 3000 kg
1 a mu = 1.66054 x 10^-27 kg
4.028 amu x 1.66054 x 10^-27 kg/a mu = 6.6828 x 10^-27 kg
The number of moles of ^2H2 gas in 3000 kg is:
n = mass/molecular weight
n = 3000 kg/6.6828 x 10^-27 kg/mol
n = 4.4905 x 10^29 mol
^2H + ^2H → ^3He + ^1n
Energy released = 2.0265 x 10^12 J
This is the energy released when 3.00 metric tons of ^2H2 gas undergoes nuclear fusion. In scientific notation, this is:
2.0265 x 10^12 J.

What mass of oxygen reacts during the incomplete combustion of 18.0 g of propane?

Answers

Answer:

Explanation:

From your balanced equation in the first part, you can see that 2 moles propane  need 7 moles O2

Find the number of moles of propane in 18 gm

   mole wt of propane = ~  12 * 3 + 8 *1 = 44 gm/mole

      18 gm /  44 gm/mole  =  9/22 gm/mole  propane

            we need 7/2 of this as O2 moles    7/2 * 9/22 = 1.432moles of O2

 O2   mole weight =~ 32

       1.432 moles * 32 gm/mole = 45.82 gm O2

Taking into account the definition of molarity,  the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution is 37.5 [tex]\frac{moles}{liters}[/tex].

Definition of molarity

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

[tex]Molarity=\frac{number of moles}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liters}[/tex].

This case

In this case, you have:

number of moles= 30 molesvolume= 0.80 L

Replacing in the definition of molarity:

[tex]Molarity=\frac{30 moles }{0.80 L}[/tex]

Solving:

Molarity= 37.5 [tex]\frac{moles}{liters}[/tex]

Finally, the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution is 37.5 [tex]\frac{moles}{liters}[/tex].

Δ[tex]T_{f}[/tex] is change in the freezing point of the solvent . [tex]K_{f}[/tex] of benzene = 5.12°C/mm is molality of the solution

Answers

The answer is 58.4 g of H₃PO₄

Given that mass of Ca₃(PO₄)₂ is 153g

mass of H₂SO₄ is 87.6g

We need to calculate the mass of H₃PO₄

So the balanced chemical reaction is

Ca₃(PO₄)₂  +  3H₂SO₄  ⇒   3CaSO₄  +  2H₃PO₄

Let us calculate the molar mass of the reactants

Ca₃(PO₄)₂ = (3 x 40) + (2 x 31) + (8 x 16)

= 120 + 62 + 128

= 310 g

H₂SO₄ = (1 x 2) + (32 x 1) + (16 x 4)

= 2 + 32 + 64

= 98 g

Now let us calculate the limiting reactant

The Theoretical Yield =  Ca₃(PO₄)₂ / H₂SO₄

= 310 / 3(98)

= 1.05

The Experimental yield

Ca₃(PO₄)₂ / H₂SO₄

= 153 / 87.6 = 1.74

Because the observed percentage was more than the predicted proportion, H2SO4 is the limiting reactant.

Let us Calculate the molar mass of H₃PO₄

H₃PO₄ = (1 x 3) + (31 x 1) + (16 x 4)

= 3 + 31 + 64

= 98 g

Now Calculate the mass of H₃PO₄

3(98) g of H₂SO₄ ------------------ 2(98) g of H₃PO₄

87.6 g of H₂SO₄ ------------------  x

x = ( 87.6 x 2 x 98) / (3 x 98)

x = 17169.6 / 294

Nitrogen gas reacts with oxygen gas to form dinitrogen tetroxide. When the equation is written and balanced, the sum of the coefficients is 3.

Nitrogen gas reacts with oxygen gas to form dinitrogen tetroxide

By catalytically oxidizing ammonia, nitrogen tetroxide is produced; steam is employed as a diluent to lower the combustion temperature. The ammonia is converted into nitric oxide in the initial step:

 4 NH3 + 5O2   →    6 H2O  + 4 NO

The gases are further cooled and the majority of the water is condensed; the created nitric oxide is then converted to nitrogen dioxide, which is dimerized into nitrogen tetroxide:

2 NO + O2 →2 NO2

2 NO2 ⇌ N2O4

Dinitrogen tetroxide

Dinitrogen tetroxide is the chemical molecule N2O4, also known as nitrogen tetroxide (NTO) and occasionally amyl (typically among ex-USSR/Russian rocket engineers). It is a helpful reagent in the synthesis of chemicals. It and nitrogen dioxide combine to form an equilibrium combination. It has a 92.011 g/mol molar mass.

Electrolysis is the technique of causing a chemical change in a substance by passing an electric current through it. The substance either loses or gets an electron during the chemical transition (oxidation or reduction). The procedure is carried out in an electrolytic cell, a device made up of positive and negative electrodes that are kept apart and submerged in a solution with ions that are both positively and negatively charged. The chemical that needs to be converted might either be dissolved in the solution or could form the electrode.

What is Inert Gas?

Under a given set of conditions, an inert gas is a gas that does not undergo chemical reactions.The noble gases (helium, neon, argon, krypton, xenon, and radon) were previously known as "inert gases" due to their perceived lack of involvement in any biochemical processes.Because inert gases are non-reactive, they do not affect equilibrium partial pressures and thus do not affect volume.An inert gas does not react with the reactants or products; it does not change the concentration of the products and reactants. Furthermore, because the volume is constant, the concentrations are unaffected. As a result, this does not affect equilibrium.

The equilibrium position won't change if an inert gas is added. A volume change won't change the equilibrium position if the total moles of gas in the products and reactants are the same. When the volume is reduced, the process changes to create fewer moles of gas.
