The frequency of the wave is 1.33 * 10^15 Hz.

We know that a wave has both the magnitude and the direction of the wave. In this case, we can see that the electron is said to have the speed of light and we need to find the frequency of the electron.

From the wave formula;

c = λf

c = speed of light

λ = wavelength

f = frequency

c = 3 * 10^8 m/s

λ = 225 * 10^-9 m

f = ???

f = c/ λ

f =  3 * 10^8 m/s/225 * 10^-9 m

f = 1.33 * 10^15 Hz

A polymer mixture p that has number-average and weight-average molecular weights of 120,000 and 300,000 and then Number average molecular weight is 110,000 g/mol

a) The number average molecular weight (NAM) is calculate using the mole numbers of each component. In this case, we will multiple each component molecular weight by the number of moles of each one. After that we will sum them and finally to divide by the total number of moles.

NAM = (Na*MA + Nb*MB)/(Nt)

NAM = (1 mol *120000 g/mol + 1*100000 g/mol ) /(2 mol)

NAM = 110000 g/mol

The number average molecular weight for the polymer P is 110,000 g/mol

We have a polymer P made up of two monodisperse fractions.

A with molecular weight of MA = 120000 g/mol and B with MB =100000 g/mol.  

The batch contains an equal mole fraction of each component A and B.  

Let's suppose a total number (Nt) of mols 2 moles. Equal fraction means XA = 0.5 and XB =0.5

Nt = 2 mol

Na = 2*0.5 = 1 mol

Nb = 2*0.5 = 1 mol.

So, we have 1 mol of A, 1 mol of B and 2 moles in total.

Any atom can differ in the amount of any of the three particles in each of them.

If the number of protons is different, the atoms are of two different elements. The number of neutrons in atoms of different elements can be the same and the number of neutrons in two atoms of the same element can be different.

The number of protons in the atoms of each element is fixed to its atomic number. The atomic mass can be the same across atoms of different elements but the atomic number is the same. It is therefore accurate to say that atoms of different elements can be identified solely by the number of protons.

Figure 1 shows the melting points and the boiling points of four substances, A, B, C and D. The substance is liquid over the greatest temperature range is C.

Hence, Option 3 is correct answer.

The Melting point (MP) of a substance is defined as the temperature at which a solid melts and change from a solid state to a liquid state may coexist in equilibrium. Melting point is a physical property.

Example of melting point: Sodium chloride (NaCl) is an ionic compound. Sodium chloride (NaCl) is made up of strong ionic bonds and it melts at only high temperatures that is 801°C.

Boiling point is defined as the particular temperature where the liquid-gas phase change occurs and the vapor pressure of a liquid equals the external pressure surrounding the liquid.

1. A

2. B

3. C

4. D

Differences in the melting point and pKa values between the maleic (Z- or cis-isomer) and fumaric (E- or trans-isomer) acid stem from differing in the orientation of carboxylic groups around the double bond.

Fumaric acid has a much higher melting point (287 degrees Celsius) than maleic acid (135 degrees Celsius). This is because maleic acid forms an intramolecular H-bond between the two carboxylic groups (due to their proximity to one another), which means that it cannot form such a bond with other molecules, weakening the intermolecular interactions and lowering the melting point.
Fumaric acid has pKa values of 3.03 and 4.44, while the values for maleic acid are 1.9 and 6.07. This means that the maleic acid will much more easily lose the first proton, but then lose the other one with more difficulty. This is again due to the proximity of the two carboxylic groups. The first proton is easily lost because upon its leave, the remaining one is bound through an additional H-bond to the other carboxylic group, making it more difficult to remove.

The molar volume of gas is 20.48 liter/mol.

We need to know about molar volume to solve this problem. The molar volume is defined as how much volume is in one mole of the substance. It can be calculated by this equation

Vm = V / n

where Vm is molar volume, V is the volume of the substance and n is the total amount of substance in moles.

From the question above, the given parameters are

n = 5.47 moles

V = 112 L

By substituting the given parameter, we can calculate the molar volume

Vm = V / n

Vm = 112 / 5.47

Vm = 20.48 L/mol

Hence, the molar volume of gas is 20.48 liter/mol.

A monolayer is containing 3.18×10-6 g of oleic acid has an area of 20.0 cm2, thus the thickness of the monolayer is calculated as    1.777 × 10⁻⁷ cm

Using,

Density = Mass / Volume

It is given that:

Area = 20.0 cm²

Density = 0.895 g/mL

Mass = 3.18 × 10⁻⁶ g

Then, applying the density formula as:

0.895 g/mL = 3.18 × 10⁻⁶ g / Volume (ml)

Volume = 3.55 × 10⁻⁶ mL

Since, 1 mL = cm³

So, Volume = 3.55 × 10⁻⁶ cm³

Thickness of monolayer = ?

An acid is able to produce ions in the aqueous solution because polar H-A bond break due to the attraction between H atoms and the O atoms of water.

In Chemistry, a substance that produces hydrogen ions along with a conjugate base is called acid.

After dissolving in water, the constituents of acid break apart forming hydrogen ions or H+ ions which react with water molecules to form hydronium ions i.e. H3O+. Thus making the solution more acidic.

The general formula of an acid shows that it contains a halogen atom, an oxygen atom and hydrogen atoms.

For example, the dissociation of H2SO4 in water produces H+ ions and SO4- ions.
