Fission is the formation of two smaller atoms by the collision of the neutrons. The quantity of energy produced per gram is 7.23 × 10¹⁰ J/g.
What is nuclear fission?Nuclear fission is a process in which the neutron collides with the atom and results in the formation of two isotopes.
The nuclear fission reaction is shown as,
[tex]\rm ^{235}_{92}U + ^{1}_{0} n \rightarrow ^{144}_{54} Xe + ^{90}_{38}Sr + 2^{1}_{0}n[/tex]
Energy in joules is calculated by the Einstein's formula as:
[tex]\begin{aligned} \rm E &= \rm mc^{2}\\\\&= 3.139 \times 10^{-28} \times (2.99 \times 10^{8})^{2}\\\\&= 2.82 \times 10^{-11}\;\rm J\end{aligned}[/tex]
Energy per gram is calculated as:
[tex]\begin{aligned}& =\dfrac{ (2.82 \times 10^{-11})(6.022 \times 10^{26})}{235.043}\\\\&= 0.0722 \times 10^{12}\\\\&= 7.23 \times 10^{10} \;\rm J/g\end{aligned}[/tex]
Therefore, the energy per gram of the fission is [tex]7.23 \times 10^{10} \;\rm J/g.[/tex]

The hybridization of nitrogen in NH4NO3
Answers
Answer:
In chemistry, orbital hybridisation (or hybridization) is the concept of mixing atomic orbitals into new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) suitable for the pairing of electrons to form chemical bonds in valence bond theory. Hybrid orbitals are very useful in the explanation of molecular geometry and atomic bonding properties and are symmetrically disposed in space. Although sometimes taught together with the valence shell electron-pair repulsion (VSEPR) theory, valence bond and hybridisation are in fact not related to the VSEPR model.

C
, a saturated solution of potassium chloride will contain
34 g
of dissolved salt for every
100 g

As you know, a saturated solution is a solution that holds the maximum amount of dissolved salt. Adding more solid to a saturated solution will cause the solid to remain undissolved.
In your case, you can create a saturated solution of potassium chloride by dissolving
34 g
of salt in
100 g
of water at
20

After absorbing 0.500 kJ of energy, a 55.5 g sample of an unknown substance has a temperature increase of about 14 degrees Celsius. Identify the substance.
Group of answer choices:
A.) Gold
B.) Iron
C.) Silver
D.) The substance is not listed.
E.) Calcium
Answers
Identified substance which is present in the sample of 55.5g is calcium, because the calculated and actual specific heat is almost same.
What is the relation between specific heat and absorbed heat?Relation between the amount of absorbed heat and specific heat of any substance is shown by following equation:
Q = mcΔT, where
Q = absorbed heat = 0.500kJ = 500Jm = mass of unknown substance = 55.5 gc = specific heatΔT = change in temperature = 14 degrees CelsiusOn putting all these values on the above equation, we get
c = 500 / (55.5)(14) = 0.643 J/g. degrees Celsius
And this value is almost equal to the given specific heat value of calcium, so the given substance is calcium.
Hence the given unknown substance is calcium.

15) A 12.0 g sample of helium gas occupies a volume of 12.6 L at a certain temperature and
pressure. What volume does a 24.0 g sample of neon occupy at these conditions of
temperature and pressure?
Answers
The required volume of sample of neon occupy at these conditions of temperature and pressure is 25.2L.
How do we convert grams into moles?Mass (W) in grams of helium gas will be converted into moles (n) by using the below equation:
n = W/M, where
M = molar mass = 4g/mol
Initial moles of helium gas:n = 12g / 4g/mol = 3 mol
Final moles of neon gas:n = 24g / 4g/mol = 6 mol
And for this question as pressure and temperature for both the conditions is constant so ideal gas equation becomes:
V₁/n₁ = V₂/n₂, where
V₁ = initial volume = 12.6 L
n₁ = initial moles = 3 mol
V₂ = final volume = ?
n₂ = final moles = 6 mol
On putting these values, we get
V₂ = (12.6)(6) / (3) = 25.2 L
Hence required volume of neon gas is 25.2 L.

How many moles of Na2O are in 350 mL of 1.2 M solution?
Answers
Answer:
0.42 moles Na₂O
Explanation:
Molarity: 1.2 M
Volume (mL): 350 mL
Volume (L): 0.35 L
350 mL / 1,000 mL = 0.35 L Na₂O
Molarity (M) = moles / liters (L)
1.2 M Na₂O = ? moles / 0.35 L Na₂O
(1.2 M Na₂O) x (0.35 L Na₂O) = ? moles
? = 0.42 moles Na₂O
