if 100. ml of 0.100 m na2so4 is added to 200. ml of 0.150 m nabr, what is the concentration of na ions in the final solution? assume that the volumes are additive.

Answers

Answer 1

The concentration of sodium ion in the final solution containing 100 ml of 0.100 m Na₂SO₄ and 200 ml of 0.150 m NaBr is 0.167 M.

The concentration of Na₂SO₄ is given as 0.100 M. So it is clear that 0.100 mol of Na₂SO₄ is present in 1 L of solution.

One mole of Na₂SO₄ contains 2 moles of Na⁺ ions and one mole of SO₄²⁻ ion.

Therefore, the concentration of  Na⁺ ion can be calculated as follows:

Concentration of  Na⁺ ions (M₁) = 2×0.100 M

                                                   = 0.2 M

Volume of Na₂SO₄ (V₁) = 100 mL

Similarly, 0.150 M NaBr is taken, which implies that 0.150 moles of NaBr are present in 1 L of solution.

One mole of NaBr contains 1 mole of Na⁺ ions and one mole of Cl⁻ ion.

Therefore, the concentration of Na⁺ ion (M₂) = 0.150 M

Volume of NaCl (V₂) = 200 mL

It is known that, M₁V₁ + M₂V₂ = MV

Where V is the total volume of solution, that is 100 mL+200 mL = 300 mL and M is the concentration of Na⁺ ion in the final solution. Equating values of M₁, V₁, M₂, and V₂ in the above equation is as follows:

0.2 M×100 mL +0.150 M×200 mL = M×300 mL

⇒M=0.2 M × 100 mL + 0.150 M × 200 mL/ 300 mL

⇒M= 0.1666 M

⇒M=0.167 M

Hence, the concentration of Na⁺ ion in the final solution is 0.167 M.

Answer:

Type the correct answer in the box. Express the answer to two significant figures. Given: N2 + 3H2 → 2NH3 Use the bond energies to calculate the change in enthalpy for the reaction. The enthalpy change for the reaction is [ ]kilojoules.

Answers

By using the bond energies given (picture attached) the change in enthalpy for the reaction will be -78 KJ

Bond energy of N≡N = 942 KJ/mol

Bond energy of H-H = 432 KJ/mol

Bond energy of N-H = 386 KJ/mol

Enthalpy change of the reaction = ?

Enthalpy change is the amount of heat evolved or absorbed during a chemical process.

The balanced chemical equation for the given reaction

    N₂ + 3H₂  →  2NH₃

So,

    number of moles of N≡N bonds = 1

    number of moles of H-H bonds = 3

    number of moles of N-H bonds = 2(3) = 6

In the first step bond breakage occurs between N≡N and H-H, as bond breakage absorbed heat so we use the plus sign here. In the second step bond formation releases energy so we use the minus sign here.

Calculate the enthalpy of the reaction

    Enthalpy of reaction = (1 × BE of N≡N) + (3 × BE of H-H) - (6 × BE of N-H)

    BE = bond energy

Put the bond energy values

    Enthalphy of reaction = (1 × 942) KJ + (3 × 432) KJ - (6 × 386 ) KJ

    Enthalphy of reaction =  -78 KJ

How many electron pairs are present in a bond between two atoms is known as the bond order. A covalent bond between two atoms has a bond order of one for all single bonds, double bonds, triple bonds, quadruple bonds, and so forth.

O2 has a bond order of 2 and two unpaired electrons in its π* orbitals.

Over O2⁻, O2⁺ is more stable. Reason: O2+ has 15 electrons total, with one of those electrons in an antibonding orbital, according to the molecular orbital theory. There are 17 electrons in the case of O2 and 3 electrons are in antibonding orbitals. An unstable molecule results from having an excessive amount of electrons in antibonding orbitals.

Bond Order = (10 - 6) / 2

                    = 2

The O2 molecule is paramagnetic because it contains two unpaired electrons.

It possesses two unpaired electrons, and an octet can be completed with just two electrons. It doesn't have an unpaired electron because the other oxygen atom can share its two electrons with it. The molecule is described as being diamagnetic if there are no unpaired electrons. In a magnetic field, diamagnetic materials are repelled.

What is the mass number?

The total number of protons and neutrons in an atomic nucleus is known as the mass number, sometimes known as the atomic mass number or nucleon number. It is roughly equivalent to the atom's atomic mass expressed in an atomic mass unit.

It is calculated by adding the total amount of protons and neutrons. For instance, the atomic number of magnesium is 4, while the atomic number of lithium is 4, which is equal to the number of protons. Eight ( 4 + 4 ) is the mass number.

Because it indicates the mass of all the protons and neutrons in an element, the mass number of an element is designated as such. The atomic number and atomic mass of an element are often listed in periodic tables along with the chemical symbols for each element.

The minimum mass of ethane that could be left over by the chemical reaction is 5.33 grams.

What is ethane?

Ethane is a two-carbon alkane that which is a colorless and odorless gas. Ethane is isolated on the industrial scale from natural gas at standard temperature and pressure and as a by-product of petroleum refining.

Given mass of ethane = 15.33 grams

Mass of oxygen = 18.0 grams

We know, molar mass ethane = 30.07 g/mol

and Molar mass oxygen = 32.0 g/mol

2C2H6 + 7O2 → 4CO2 + 6H2O

Moles of ethane = 15.33 grams / 30.07 g/mol

Moles of ethane = 0.509 moles

Moles of oxygen = 18.0 grams / 32.0 g/mol

Moles of oxygen = 0.562 moles

For 2 moles ethane ,we would need 7 moles oxygen to produce 4 moles CO2 and 6 moles H2O

Oxygen is limiting reactant and it will be consumed completely.

0.562 / 3.5 = 0.160 moles

Remaining will be-  0.509 - 0.160 = 0.349 moles
