Charge can be transferred from one object to another in three way conduction, polarization, and friction

Whenever electrons are transferred between objects, neutral matter becomes charged and three ways this can occur are referred to as conduction, polarization, and friction conduction means when there is direct contact between materials that differ in their ability to give up or accept electrons when two different materials are rubbed together, there is a transfer of electrons from one material to the other material and this causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer)

Here given object is water + balloon; balloon + wall; tape then you rub a balloon against your clothes and it sticks to the wall, you are adding a surplus of electrons (negative charges) to the surface of the balloon the wall is now more positively charged than the balloon and we tested the conductivity of deionized water positively charged

The sequence of amino acid residues in a protein is considered primary structure and is always read from the N-terminal end of protein.

The food we eat chiefly consists of three nutrients namely carbohydrates, proteins and fats.

Proteins are the most abundant among the bio molecules present in the living organisms.

The word protein is derived from Greek word, “proteios” which means primary or of prime importance.

The proteins are the polymers of amino acids.

The structure of amino acid consists of a carbon atom surrounded by four functional groups i.e, Carboxyl(COOH) group, the Amino(NH2) group, hydrogen(H) and an alkyl group(R).

In a protein, amino acids are linked to each other by peptide bonds which are formed between the COOH group of one amino acid and the NH2 group of another amino acid, as shown in the adjoining image.

In primary structure, the amino acids are joined to each other in a linear manner without any branching, as shown in the given diagram.

A chemical reaction's rate and the concentrations of the reactants involved are correlated by an expression known as the rate law, commonly referred to as the rate equation or rate law equation.

A frequent way for determining rate laws is the concept of beginning rates. The method includes determining the starting rate of a reaction, as the name initial rate method would imply. To observe how the reaction rate varies, the measurement is repeated for several sets of beginning concentration conditions.

Molecular formula of a molecule is C₂H₂.

Empirical formula gives the proportion of the elements present in a compound.

The proportion od carbon and hydrogen is 1 : 1.

n(C) : n(Cl) = 1 : 1

n(C) = n(H) = n; amount of substance of carbon and hydrogen is the same in a molecule

M(molecule) = 26 g/mol; molar mass of a molecule

M(C) = 12 g/mol; molar mass of carbon

M(H) = 1 g/mol; molar mass of hydrogen

M(molecule) = n × M(C) + n × M(H)

M(molecule) = n × 12 g/mol + n × 1 g/mol

26 g/mol = n × 13 g/mol

n = n(C) = n(H) = 2

Frequency, wavelength and speed of light are connected to each other by the formula

c= f * w

where c is the speed of light

f is the frequency of light

w is the wavelength

We are required to find the frequency of light at different wavelengths as provided in the question

We would use the speed of light as 3 x 10^8 m/s

Case 1:

when the wavelength is 200 nm

a nm is a unit of the scale 10^-9m

Using the formula,

c= f *w

3 x 10^8 = f x 200 x 10^-9

f = 3 x 10^8/200  x 100^-9

  = 1.5 x 10^17 Hz

Case 2:

when the wavelength is 30pm

a pm is a unit of the scale 10^-12m

c = f *w

3 x 10^8 = f  x 30 x 10^-12

f = 3 x 10^8 / 30 x 10^-12

f= 10^19Hz

Case 3:

when the wavelength is 10km

a km is a unit of the scale 10^3m

c = f *w

3 x 10^ 8 = f x 10 x 10^3

f =3 x 10^8 / 10x 10^3

f = 3 x 10^4 Hz

Hence the frequencies are 1.5 x 10^17 Hz, 10^19Hz,3 x 10^4 Hz

When Methane thiol, CH₃SH, reacts with O₂, 25.8 grams of Sulfur dioxide, SO₂ is formed and limiting reactant is Oxygen, O₂.

The balanced chemical reaction is:

CH₃SH(g) + 3 O₂(g) → 2 H₂O(g) + CO₂(g) + SO₂(g)

             Molecular weights:       Actual/given mass:

CH₃SH = 48.11 g/mol                    27.3 g      

O₂         = 32.01 g/mol                    38.6 g  

H₂O      = 18.01 g/mol            

CO₂      = 44.01 g/mol                  

SO₂       = 64.06 g/mol

Number of moles =    Given mass    

                                  Molecular mass

So,

moles of methane thiol = 27.3 ÷ 48.11= 0.56 moles

moles of oxygen = 32.01÷38.6 = 0.82 moles

From the reaction,

1 mole of CH₃SH reacts with 3 moles of O₂  to give 1 mole of SO₂

Thus, 0.56 moles of CH₃SH reacts to form 1 × 0.56 = 0.56 moles of SO₂

Mass of SO₂ produced is 0.56 × 64.06 g = 35.86 g

moles of SO₂ = 35.86 ÷ 64.06 = 0.55 moles

So,
