The required volume of sample of neon occupy at these conditions of temperature and pressure is 25.2L.

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

n = 12g / 4g/mol = 3 mol

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.

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.

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]

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

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.

Answer:

1. Conduction

2. Convection

Explanation:

1. Conduction is the transfer of energy from one end of something to the other. Since the pad is heating up your back and no fluids or gasses are involved it is conduction.

2. Convection is the transfer of energy through air. Since the air is transferring its energy to the ice it is convection.

Answer:

6

Explanation:

Count the number of species that are bonded to chromium in this complex ion. There are four ammonia molecules and two chlorine atoms bonded to chromium. This yields a coordination number of 6.

The co-ordination number of chromium ion in complex [Cr(NH₃)₄Cl₂][tex]^+[/tex] is six as there are four ammonia molecules and 2 chlorine molecules bonded to chromium which gives total co-ordination number of 6.

An ion is defined as an atom or a molecule which has a net electrical charge. There are 2 types of ions :1) cation 2) anion . The cation is the positively charged ion and anion is the negatively charged ion . As they are oppositely charged they attract each resulting in the formation of ionic bond.

Ions consisting of single atom are mono-atomic ions while which consists of two or more ions are called as poly-atomic ions . They are created by chemical interactions . They are very reactive in their gaseous state and rapidly react with oppositely charged ions resulting in neutral molecules.
