If the photon has a frequency of   3.16 × 10 ⁷ Hz, then the energy of the the photon as per Planck's law would be 1.978× 10⁻²⁶ Joules

It can be understood in terms of the distance between any two similar successive points across any wave.

C = λν

As given in the problem we have to calculate the energy of the light if the frequency of light is  3.16 × 10 ⁷ Hz

The energy of the photon = h ν

                                           = 6.26 × 10⁻³⁴ × 3.16 × 10 ⁷

                                           = 1.978× 10⁻²⁶ Joules

Thus, If the photon has a frequency of   3.16 × 10 ⁷ Hz, then the energy of the the photon as per Planck's law would be 1.978× 10⁻²⁶ Joules.

To answer this question, we have to use the dilution rule, that is represented by the following equation:

Where C1 and C2 are the initial and final concentrations and V1 and V2 are the initial and final volumes.

Solve the equation for V2 to find the final volume:

The final volume of the solutions has to be 195mL. Since we already have 65mL, we need to add 130mL of water to have 195mL in total.

It means that the correct answer is 130mL.

The gas that  behaves most like an ideal gas at the conditions indicated is H2(g) molecules at 10-3 atm and 200°C

Recall that a gas is said to show an ideal behavior when the pressure of thee gas is low and the temperature of the gas is high. Recall that, at a high temperature and a low pressure, the interaction that exists between the molecules of the gas is decreased as such the molecules of the gas would tend to move faster.

We can see that the hydrogen gas has a lower pressure at the same temperature hence the interaction that is know to exists between the molecules of the gas is minimal.

The empirical formula for a compound composed of 9.93% carbon, 58.6% chlorine, and 31.4% fluorine is CCl₂F₂.

To write the empirical formula, let us assume that total mass of the compound is 100 g, then-

Mass of carbon = 9.93 g

Mass of chlorine = 58.6 g

Mass of fluorine = 31.4 g

We know that,

Molar mass of Carbon = 12.0 g/mol

Molar mass of Chlorine = 35.5 g/mol

Molar mass of Fluorine = 18.9 g/mol

Now, we will calculate the number of moles of each using the formula -

Number of moles = Given mass

                                 Molar mass

Moles of Carbon =   9.93 g     = 0.82 mol

                               12.01 g/mol

Moles of Chlorine =    58.6 g     = 1.65 mol

                                 35.5 g/mol

Moles of fluorine =    31.4 g     = 1.66 mol

                                18.9 g/mol

Now, divide each value with the smallest amount of mole we got,

carbon = 0.82 = 1

               0.82

chlorine = 1.65 =  2

                 0.82

fluorine = 1.66 = 2

                0.82

Therefore, the empirical formula of the compound can be written as - CCl₂F₂

Answer:

D) Nondisjunction

Explanation:

Nondisjunction happens when a chromosome pair doesn't separate during meiosis. A result is one of the gamates has to any chromosome, while others have much less.

Taking into account the definition of enthalpy of a chemical reaction, 2.345 moles of CH₃OH are required to give off 1501 kJ of heat

The enthalpy of a chemical reaction as the heat absorbed or released in a chemical reaction when chemicals are transformed into a chemical reaction at constant pressure.

The enthalpy is an extensive property, that is, it depends on the amount of matter present.

In this case, the balanced reaction is:

2 CH₃OH (l) + 3 O₂ (g) → 2 CO₂ (g) + 4 H₂O(g)

and the enthalpy reaction ∆H° has a value of -1280 kJ/mol.

This equation indicates that when 2 moles of CH₃OH reacts with 3 moles of O₂, 1280 kJ of heat is released.

If it is required to give off 1501 kJ of heat, you can apply the following rule of three: If 1280 kJ of heat is released by 2 moles of CH₃OH, 1501 kJ of heat is released by how many moles of CH₃OH?

amount of moles= (1501 kJ× 2 moles of CH₃OH)÷ 1280 kJ

amount of moles= 2.345 moles of CH₃OH

In summary, the amount of moles required are 2.345 moles.

Step 1

The reaction must be completed and balanced as follows:

4 FeS2 + 11 O2 => 2 Fe2O3 + 8 SO2

Step 2

Information provided:

26.62 moles of FeS2

59.44 moles of O2

-------------------------

Step 3

The limiting and the excess reactant

Procedure: by stoichiometry,

4 FeS2 + 11 O2 => 2 Fe2O3 + 8 SO2

4 moles FeS2 ------------ 11 moles O2

26.62 moles FeS2 ------------ X

X = 26.62 moles FeS2 x 11 moles O2/4 moles FeS2

X = 73.20 moles

For 26.62 moles of FeS2, 73.20 moles of O2 are needed, but there are only 59.44 moles so the limiting reactant is O2, and the excess reactant is FeS2.

Answer:

The limiting reactant = O2

The excess reactant = FeS2

The chemical element which magnesium would combine with in order to attain a subscript of 3 is nitrogen which result in the formation magnesium nitride ( Mg₃N₂ )

Magnesium is a metallic element which belongs to group 2 and and has a valence electron of 2. This means that in an electrovalent combination, magnesium loses 2 valence electrons to nitrogen to become Mg2+ ion. To complete this bonding, nitrogen which has 5 valence electrons accepts 3 of Mg2+ ions in addition with with its two N3− ions to form magnesium nitride. When this happens, magnesium then attains a subscript of 3.

Magnesium nitride is an electovalent or ionic compound and the bond which exist in it is Ionic bond. It is used in the synthesis of ceramic substances.

The question requires us to calculate the number of moles that corresponds to 5.01 x 10^22 atoms of magnesium.

To solve this question, we'll need to use the Avogadro constant. This number, defined as 6.02 x 10^23, relates the number of constituent particles (molecules, atoms or ions, for example) in a sample with the amount of substance in that sample. We can use it by saying that 1 mol of a substance corresponds to 6.02 x 10^23 constituent particles of this substance.

Then, using the information above, we can calculate the number of moles in 5.01 x 10^22 atoms of magnesium (Mg):

6.02 x 10^23 atoms of Mg --------------- 1 mol of Mg

5.01 x 10^22 atoms of Mg ---------------- x

Solving for x, we'll have:

Therefore, 5.01 x 10^22 atoms of magnesium corresponds to 0.0832 mol of this element.
