6.023 ×[tex]10^{23}[/tex]  individual carbon atoms are there in one mole of carbon.

Mass of a 1 [tex]C_{12}[/tex] atom= 12 amu

1 amu = 1.66 ×[tex]10^{-27}[/tex] gm

∴ 12 amu =1.99 ×[tex]10^{-21}[/tex] gm

∴Mass of a 1 [tex]C_{12}[/tex] atom=1.99 ×[tex]10^{-21}[/tex] gm

Mass of C in 1 mole = 12 gm

∴Total number of atoms of carbons in 1 mole = 12 ÷ 1.99 ×[tex]10^{-21}[/tex]

∴Total number of atoms of carbons in 1 mole= 6.023 ×[tex]10^{23}[/tex]  atoms

6.023 ×[tex]10^{23}[/tex]  individual carbon atoms are there in one mole of carbon.

The number 6.023 ×[tex]10^{23}[/tex]  is known as Avogadro's number, which represents the number of individual atoms present in a one mole of substance with respect to [tex]C_{12}[/tex] atoms.

Answer:

B. Nuclear fusion is the joining of two or more nuclei into one nucleus.

The best definition of nuclear fusion : Nuclear fusion is the joining of two or more nuclei into one nucleus.

Nuclear reaction, change in the identity or characteristics of an atomic nucleus, induced by bombarding it with an energetic particle.

The bombarding particle may be an alpha particle, a gamma-ray photon, a neutron, a proton, or a heavy ion.

Nuclear Fusion reactions power the Sun and other stars.

In a fusion reaction, two light nuclei merge to form a single heavier nucleus.

The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.

Answer:

This answer assumes that the strated "16.0g of iron" was meant to be 16.0 grams of iron(III) oxide.

Explanation:

To start, the thermite equation must be balanced.

I find:

1Fe2O3 + 2Al = 1Al2O3 + 2Fe

This tells us we need 2 moles of Al for every 1 mole of Fe2O3.  

Now calculate the moles of each reactant:

Moles Fe2O3:  16.0 g/159.7 g/mole = 0.100 moles Fe2O3

Moles Al:  8.1 /26.98 g/mole = 0.300 moles Al

The balanced equation says that in order to react all of the Fe2O3 we'd need twice that amount (in moles) of the Al.  (0.100 moles Fe2O3)*(2) = 0.200 moles Al.

Which of the two reactants is the limiting reagent?

We have more than enough moles of Al to react with 0.10 moles of Fe2O3.  (We have 0.300 moles Al and all we need is 0.200 moles to react with the 0.10 moles of Fe2O3.  Fe2O3 is the limiting reagent.

Calculate the maximum mass of iron of iron that could be formed using these quantities of reactants.

The balanced equation tells us that we will obtain 2 moles of Fe for every 1 mole of Fe2O3 consumed.  Since Fe2O3 is the limiting reagent, we will assume that it completely reacts.  That means 0.1 moles of Fe2O3 is reacted.  Since we expect twice that many moles of Fe, we should obtain 0.200 moles of Fe.  At 55.85 g/mole, we should obtain:

(0.200 moles Fe)*(55.85 g Fe/mole Fe) = 11.2 grams Fe

Answer: Both are highly reactive.

Explanation:

A is fluorine, which only needs to gain one more electron to have a full valence shell. Thus, it is reactive.

D is sodium, which only needs to lose one electron to have a full valence shell. Thus, it is also reactive.

The mass, in grams, of sodium chloride needed would be 27.29 grams.

The number of moles of a substance is mathematically given as:

Mole = mass/molar mass.

Thus, mass = mole x molar mass.

In this case, 0.467 moles of NaCl is needed. The mass of 0.467 moles of NaCl can then be calculated as:

Mass = 0.467 x 58.44 = 27.29 grams.

Answer:

Ionic bonding happens when an atom of an element gives one or more of its electrons to the other element's atom..it usually takes place between metal and non metal atoms...like in NaCl, Na gives its valence electron to chlorine and completes its own octet. Chlorine accepts the electron and completes its own octet too...but now both the atoms have an opposing charge and hence they attract each other to form an IONIC bond.

Ionic bonds are the strongest of the bonds...here complete transfer of electrons takes place unlike covalent bonds.

Answer:

Ni atoms are contained in 1.25gram is 1.28e22 atoms.

Explanation:

Ni atoms are contained in 1.25gram is 1.28e22 atoms.

We have a Nickel(Ni)  atom . The atomic number of Ni is 28 .It is a silvery-white metal with a slight golden tinge. Ni belongs to the transitional metal series.

The electronic configuration of Ni = Ar4d⁸35²

Nickel is slowly oxidized by air at room temperature.

Nickel is a ferromagnetic element at approximately room temperature.

To answer the problem , we first need to divide by the molar mass of Ni to get the moles of Ni. And then we will multiply by Avogadro's number to find the number of Ni atoms.

Molar mass of Ni = 58.7gm

Given mass of Ni = 1.25gm

Avogadro’s No. = 6.022 × 10²³ atom/mole

                    Moles of Ni = Given mass/Molecular mass

                                          = 1.25/58.7 = 0.0213

                    Moles of Ni = 0.0213

Now ,

       Number of Ni atom = Avogadro’s number × Moles

So that,

                No. of Ni atom = 6.022 × 10²³× 0.0213

                                            = 0.128 ×10²³  atoms

                                           = 1.28 × 10²² atoms

                                           = 1.28e22

So there are 1.28 × 10²² individual Ni atoms are contained in 1.25 grams of Ni.

Explanation:

Thomson's experimental data does support the Rutherford model.

The atom consists of matter that may be split without releasing electrical charges.

It's also the smallest unit of matter with chemical element features. As a result, the atom is the fundamental unit of science.

Rutherford was the one who first published the nuclear model of the atom. According to his atomic model, an atom's volume is largely empty,

The center of the atom houses the nucleus, which is made up of protons and neutrons, and its electrons follow certain pathways as they orbit it.

When compared to Rutherford's discoveries, the study of certain other scientists, like Dalton, Neil Bohr, and JJ Thomson, is mostly consistent.

For instance, Dalton's atomic theory assumed that atoms interact to create compounds and are nearly the same size.

Rutherford's theory states that atoms have a finite amount of electrons that may be shared to form compounds.

Rutherford's discoveries, which gave rise to the concept of shells, are also consistent with the Bohr model, which holds that electrons orbit the nucleus in certain shells.

Despite the fact that Rutherford's model was the best atomic model, it nevertheless drew from a number of prior studies and was compatible with their findings.

Hence Thomson's experimental data does support the Rutherford model.

The identity of the noble gas is the sample is Krypton

From the question, we are to determine the identity of the noble gas in the sample

From the ideal gas equation, we have that

PV = nRT

∴ n = PV / RT

Where P is the pressure

V is the volume

n is the number of moles

R is the gas constant

and T is the temperature

From the given information,

P = 678 mmHg = 0.892105 atm

V = 363 mL = 0.363 L

R = 0.08206 L.atm/mol.K

T = 35 °C = 35 + 273.15 K = 308.15 K

Putting the parameters into the equation, we get

n = (0.892105 × 0.363)/ (0.08206 × 308.15)

n = 0.0128 moles

Now, we will determine the Atomic mass of the sample

Using the formula,

Atomic = Mass / Number of moles

Atomic mass of the substance = 1.07 / 0.0128

Atomic mass of the substance = 83.6 amu

The noble gas with the closest atomic mass to this value is Krypton.

Molar mass of Krypton = 83.798 amu

Hence, the identity of the noble gas is the sample is Krypton
