Fusion releases less energy than fission

fusion most commonly combines heavy isotopes of hydrogen into helium.

Explanation:

Nuclear fusion is a form of reaction that involves the combination of two light nuclei to form one that is heavier in mass.

The other form is nuclear fission which is the splitting of heavier nuclei either spontaneously or when bombarded with other nuclei.

Nuclear fusion reactions in the core of stars powers the universe.
The reactions produces a huge amount of energy of a greater and massive order than fission reaction.
Small nuclei are involved in nuclear fusion and not the large ones.
Nuclear fusion degenerates into series of chain reactions that are extremely difficult to control.

2C4H10 + 13 02 -- 8 CO2 + 10H20

Anika [276]

Answer:

Option 1. 0.55 mol of C₄H₁₀

Explanation:

The reaction is:

2C₄H₁₀ + 13O₂ → 8 CO₂ + 10H₂O

This is a combustion reaction where carbon dioxide and water are produced.

We convert mass of produced water to moles → 50 g / 18 g/mol = 2.78 moles of water.

The stoichometry states that:

10 moles of water are made by 2 moles of C₄H₁₀

Therefore 2.78 moles of water will be made by (2.78 . 2) / 10 = 0.55 mol of C₄H₁₀

In a closed container with a fixed volume, when the temperature of a gas doubles, the pressure of the gas is?

nevsk [136]

Answer:

The pressure of the gas is:

<u>Doubled</u>

<u></u>

Explanation:

Byole's Law = Pressure of fixed amount of gas is inversely proportional to Volume at constant temperature.

PV = k = constant

P1V1 = P2V2

<u>Charle's Law: </u> The volume of ideal gas at fixed pressure is directly proportional to Pressure.

V/T = constant

V1/T1 = V2/T2

On combinig the charles and byole's law , we get:

$\frac{P_{1}V_{1}}{T_{1}}=\frac{P_{2}V_{2}}{T_{2}}$

Now , According to question :

V2 = V1

T2 = 2(T1)

We have to find the relation between the pressure :

insert the value in the equation

$\frac{P_{1}V_{1}}{T_{1}}=\frac{P_{2}V_{2}}{T_{2}}$

$\frac{P_{1}V_{1}}{T_{1}}=\frac{P_{2}V_{1}}{2T_{1}}$

V1 and V1 & T1 and T1 cancels each other,

So we get

P2 = 2 P1

So the new pressure is double of the original pressure

Question 1

OLga [1]

Answer: 7 atm

Explanation:

According to Dalton's Law, the total pressure is the sum of all the individual gas pressures

Hence, Ptotal = P1 + P2 + P3

Since, Gas A = 2 atm

Gas B = 1 atm

Gas B = 4 atm

Ptotal = (2 + 1 + 4) atm

Ptotal= 7 atm

Thus, the total pressure of the gas mixture is 7 atmosphere.

<h3>Further explanation </h3>

The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.

Usually radioactive elements have an unstable atomic nucleus.

General formulas used in decay:

$\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{t/t\frac{1}{2} }}}$

T = duration of decay

t 1/2 = half-life

N₀ = the number of initial radioactive atoms

Nt = the number of radioactive atoms left after decaying during T time

Nt=25 g

No=100 g

t1/2=5770 years

$\tt 25=100\dfrac{1}{2}^{T/5770}\\\\\dfrac{1}{4}=\dfrac{1}{2}^{T/5770}\\\\2=T/5770\rightarrowT=11540~years$

The (triangle)Hrxn of formation of carbon dioxide is negative. Which statement is true? The reaction is endothermic. The reactio

ANEK [815]

The negative ion reactions that consist of the formation of carbon dioxide in the atmosphere is generally an exothermic reaction. By definition, an exothermic reaction takes place when the chemical process eventually releases heat as its by-product. It is in contrast in endothermic process wherein heat is absorbed.
