What produces the large amount of energy released by a nuclear reaction?

1 answer:

3 0

Fusion power is the power generated by nuclear fusion processes. In fusion reactions, two light atomic nuclei fuse together to form a heavier nucleus. In doing so, they release a comparatively large amount of energy that arises from the binding energy, creating an increase in temperature of the reactants.

What is the temperature of 0.52 mol of gas at a pressure 131.722kpa and a volume of 11.8l

SpyIntel [72]

The temperatue is 0.4 K.

Answer:

Explanation:

As per the kinetic theory of gases, the product of pressure with volume will be equal to the product of concentration and volume. This law is formed by combination of Charle's law and Boyle's law.

Here n = 0.52 mo; P = 131.722 kpa, V = 11.81.

PV = nRT

Here n is the mole concentration, P is the pressure and V is the volume.

(131.722× 10³×11.8)=(0.52×8.314×T)

1.554 = 4.32 T

T = 1.554/4.32=0.4 K

T = 0.4 K.

Thus, the temperatue is 0.4 K.

In which species does sulfur have the highest oxidation number? s8 (elemental form of sulfur) h2s so2 h2so3 k2so4?

Mashutka [201]

There are rules to assigning conventional oxidation numbers to some elements. For those unspecified, you can solve them. This is how you solve it.

*S8. Since this is in elemental form, its oxidation number is assigned as 0.

*H2S. H is assigned with +1. Since the compound is neutral, the overall charge is 0. So,
2(+1) + x = 0
x = -2
The charge of S here is -2.

*SO₂. O is assigned with (-2). Using the same procedure,
x + 2(-2) = 0
x = +2
The charge of S here is +2.

*H₂SO₃.
2(+1) + x + 3(-2) = 0
x = +4.
The charge of S here is +4.

*K₂SO₄. K is assigned with +1.
2(+1) + x + 4(-2) = 0
x = +6
The charge of S here is +6.

The S with the highest oxidation number is the one in K₂SO₄.

For this device the liquid to be tested is drawn into the tube to a level above the top etched line. The time is then obtained f

N76 [4]

Answer:

The dynamic viscosity of the liquid is 0.727 kg/m*s

Explanation:

In the equation for that viscosimeter, ν = KR⁴t, the terms K and R are not dependent on the liquid that is being tested, unlike ν and t.

Using that equation and the data given in the problem, we can calculate the product of K and R⁴.

1.19*10⁻³m²/s = (KR⁴)* 1430 s

KR⁴=8,32*10⁻⁷m²/s²

We can now calculate the kinematic viscosity of the unknown liquid.

ν=8,32*10⁻⁷m²/s²*900s

ν=7.49*10⁻⁴m²/s

The relationship between the kinematic viscosity and the dynamic viscosity is given by the equation μ=ν * ρ, where μ is the dynamic viscosity and ρ is the density. Thus:

μ=7.49*10⁻⁴m²/s * 970 kg/m³

μ=0.727 kg/m*s

What is the difference between a solution and a heterogeneous mixture?

Len [333]

A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.

What volume of hydrogen gas, when combined with nitrogen gas,

Westkost [7]

The volume of Hydrogen gas : 24 L

<h3>Further explanation</h3>

Given

16 L Ammonia(NH₃)

Required

The volume of Hydrogen gas

Solution

Reaction

N₂ + 3H₂ ⇒ 2NH₃

Avogadro's hypothesis:

In the same T,P and V, the gas contains the same number of molecules

So the ratio of gas volume will be equal to the ratio of gas moles

V₁/n₁=V₂/n₂

From the equation, mol ratio of H₂ : NH₃ = 3 : 2, so volume of H₂ :

= 3/2 x volume of NH₃

= 3/2 x 16 L

= 24 L
