based on nuclear stability, what is the symbol for the most likely product nuclide when carbon-10 undergoes decay?

The component that will limit the reaction is:

a. HCl (Hydrochloric acid)

To determine the limiting reagent in the given chemical reaction, we need to compare the moles of each reactant to the stoichiometric ratio of the balanced equation.

Let's calculate the number of moles for each reactant:

For Zn:

Molar mass of Zn = 65.38 g/mol

Number of moles of Zn = mass / molar mass = 3.27 g / 65.38 g/mol ≈ 0.05 mol

For HCl:

Molar mass of HCl = 36.46 g/mol

Number of moles of HCl = mass / molar mass = 3.30 g / 36.46 g/mol ≈ 0.09 mol

According to the balanced equation, the stoichiometric ratio between Zn and HCl is 1:2. This means that for every 1 mole of Zn, we need 2 moles of HCl.

In this case, the number of moles of Zn (0.05 mol) is less than half of the number of moles of HCl (0.09 mol). Therefore, Zn is the limiting reagent, as it will be completely consumed before all the HCl can react.

So, the component that will limit the reaction is:

a. HCl (Hydrochloric acid)

Answer:

Rubidium (Rb).

Explanation:

From the question given above, the following data were obtained:

Electronic configuration => 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s¹

Name of element =?

To know the name of the element with the above electronic configuration, we shall determine the atomic number of the element. This can be obtained as follow:

Number of electrons = 2 + 2 + 6 + 2 + 6 + 2 + 10 + 6 + 1

Number of electrons = 37

Next, we shall determine the number of protons. This can be obtained as follow:

From the question given above, the element has no charge. Hence the element contains equal numbers of protons and electrons.

Number of electrons = 37

Number of protons = number of electrons = 37

Next, we shall determine the atomic number. This can be obtained as follow:

The atomic number of an element is simply defined as the number of protons present in the atom of the element. Thus,

Atomic number = proton number

Proton is = 37

Therefore,

Atomic number = 37

Finally, we shall determine the name of the element by comparing the atomic number of those in the periodic table.

Thus, the element with the above electronic configuration is Rubidium (Rb) since no two elements have the same atomic number

Answer:

B.) Na₂SO₄

Explanation:

Covalent bonds are bonds which involve electrons being shared between two atoms. These bonds only occur between nonmetals.

Ionic bonds are bonds which involve electrons being given or taken by two atoms. These bonds form between a metal and a nonmetal.

NH₃ contains nitrogen and hydrogen, two nonmetals. Therefore, this molecule only contains covalent bonds.

Na₂SO₄ has both covalent and ionic bonds. The covalent bonds are found within the polyatomic ion, SO₄²⁻. Sulfur and oxygen are both nonmetals, thus covalently combining. The ionic bond forms between the  Na⁺ and SO₄²⁻. Sodium (Na) is a metal which wishes to give up electrons to have a complete octet. SO₄²⁻ serves as the anion which it bonds with.

CH₃COOH contains hydrogen, carbon, and oxygen. All of these are nonmetals, thus the only bonds formed are covalent.

NaCl contains sodium, a metal, and chlorine, a nonmetal. Therefore, this compound is held together by an ionic bond.

Cu(NO₃)₂: water, CS₂: hexane, CH₃CH₂OH: water, CH₃(CH₂)₁₆CH₂OH: water, HCl: water, C₆H6: hexane.

Polar solvents dissolve ionic and polar compounds, while non-polar solvents dissolve nonpolar compounds. The ionic compound Cu(NO₃)₂ will dissolve in water because water is a polar solvent, and it can form ion-dipole bonds with the ions. CS₂ is a nonpolar compound; it will dissolve in hexane because hexane is a nonpolar solvent. CH₃CH₂OH is a polar molecule that can form hydrogen bonds with water molecules; thus, it is soluble in water.

CH₃(CH₂)₁₆CH₂OH is a long-chain alcohol that can also form hydrogen bonds with water molecules, making it soluble in water. HCl is an ionic compound that will dissolve in water, which is a polar solvent. C₆H₆ is a nonpolar compound that can dissolve in hexane. Therefore, the solvent that will dissolve each of the above compounds are as follows:

a. Cu(NO₃)₂: water

b. CS₂: hexane

c. CH₃CH₂OH: water

d. CH₃(CH₂)₁₆CH₂OH: water

e. HCl: water

f. C6H6: hexane.

C₂H₆, compound has a C-H bond with the lowest bond dissociation energy, hence option A is correct.

Toluene has the lowest bond dissociation energy because it undergoes hyper conjugation with the C-H protons.

The energy needed to break a bond and create two atomic or molecular fragments, each containing one of the original shared pair of electrons, is known as the bond dissociation energy.

As a result, an extremely stable bond has a high bond dissociation energy, meaning additional energy is required to break the binding.

Answer: oxidation reactions

Explanation:

During the formation of a coordination compound, the metal acts as a central atom or cation.

What is a  coordination compound?

A coordination compound is a complex formed by the attachment of one or more ligands to a central metal ion. Ligands are molecules or ions that donate electrons to the metal ion, creating coordinate bonds. These compounds often exhibit unique properties due to the coordination of ligands with the central metal ion.

In a coordination compound, the central atom or cation is typically a metal ion that acts as the core around which the ligands coordinate. The metal ion is responsible for accepting electron pairs from the ligands to form coordinate bonds.

These bonds are formed through the interaction between the lone pairs of electrons on the ligands and empty orbitals on the metal ion.

The metal ion's ability to accept and coordinate with ligands is due to its vacant d orbitals, which can accommodate the shared electron pairs from the ligands.

This coordination process results in the formation of a coordination complex, where the metal ion is surrounded by ligands. The coordination number of the metal ion corresponds to the number of ligands directly bonded to it.

Answer:

The acceleration of the car will increase drastically

Explanation:

Based on newtons second law of motion, the force applied on a body is directly proportional to the product of its mass and acceleration;

     Force  = mass x acceleration

Since the mass of the car is constant, an increase in force will cause an increase in acceleration.

A decrease in the force will impact a lesser acceleration on the motor car.

This way, the change in velocity of the body per unit of time will increase drastically.

As the volume was decreased and pressure increased to the given values, the new temperature of the ideal gas is 226.9°C.

Combined gas law put together both Boyle's Law, Charles's Law, and Gay-Lussac's Law. It states that "the ratio of the product of volume and pressure and the absolute temperature of a gas is equal to a constant.

It is expressed as;

P₁V₁/T₁ = P₂V₂/T₂

Given the data in the question;

To calculate the new temperature the gas, we subtsitute our given values into the expression above.

P₁V₁/T₁ = P₂V₂/T₂

P₁V₁T₂ = P₂V₂T₁

T₂ = P₂V₂T₁/P₁V₁

T₂ = ( 4.00atm × 1.50L × 305.15K ) / ( 1.04605atm × 3.50L )

T₂ = 1830.9LatmK / 3.661175Latm

T₂ = 500.085K

T₂ = 226.9°C

Therefore, as the volume was decreased and pressure increased to the given values, the new temperature of the ideal gas is 226.9°C.
