The occurrence of elements properties in which it repeats every after the eight elements named a periodicity.

Periodicity would be the reappearance of identical features in an element's behavior when it is organized in atomic number-increasing at frequent intervals.

The repeating of a comparable electronic configuration of an element's atoms in its outermost electron shell after such a predetermined regular interval that's what causes periodicity in its properties.

The elements were organized by chemist John A. R. Newland in order of increasing their atomic weight. He gave it the name "the principle of Octaves" and described how a particular collection of qualities recurs every eight places.

The component missing from the process of photosynthesis is carbon dioxide. Carbon dioxide is an essential component of photosynthesis as it is used by plants to create glucose, which is the primary energy source for plants.

Carbon dioxide (CO2) is a colorless, odorless gas that is produced when carbon-containing compounds are burned. It is one of the most abundant trace gases that make up the Earth’s atmosphere. Carbon dioxide is important in the Earth’s natural cycle of life as plants use it to produce food through photosynthesis, while animals and humans exhale it as a waste product. In the atmosphere, carbon dioxide acts as a greenhouse gas and helps regulate the Earth’s temperature.

Carbon dioxide is taken in by the leaves of the plant and then combined with water and energy from sunlight to form glucose. Without carbon dioxide, photosynthesis would not be possible.

The pH of the final solution will be less than 7, but closer to 7 if the initial concentration of sodium acetate is high and the concentration of HCl is low.

The pH of a solution after a reaction with a strong acid like HCl will depend on the concentration of the acid and the concentration of the acetate ions (CH3COO-) in the sodium acetate solution. Sodium acetate (CH3COONa) is a weak base, and when it reacts with HCl, it forms acetic acid (CH3COOH) and sodium chloride (NaCl). The equation for this reaction is: CH3COONa + HCl → CH3COOH + NaClThe pH of a solution is a measure of the concentration of hydronium ions (H3O+) in the solution, so the pH of the solution after the reaction will depend on the concentration of H3O+ ions and the concentration of acetate ions. If the reaction is done in aqueous solution, the acetic acid formed will dissociate to form H3O+ and acetate ions. The acetate ions will neutralize some of the H3O+ ions, thus decreasing the overall acidity of the solution. The pH of the final solution will be less than 7, but closer to 7 if the initial concentration of sodium acetate is high and the concentration of HCl is low. It's important to note that without knowing the initial concentration of sodium acetate and the volume of the solutions it is not possible to determine the final pH.

The remaining mass of hydrogen that is present in the reaction is 0.20 grams.

The balanced chemical reaction can be depicted as follows:

2H2+O2---->2H2O

1 mole of Oxygen reacts with 2 moles of Hydrogen in order to produce two moles of water i.e., H2O.

0.15 moles of O2  reacts with 2 * 0.15 = 0.30 moles of H2

The moles of H2 are given i.e., 0.40 moles.

So remaining = 0.40 moles - 0.30 moles = 0.10 moles

Thus, the mass of H2 can be calculated by multiplying the number of moles with the molar mass that is expressed as follows:

Mass = moles * molar mass

Molar mass of H2= 2 g/mol

Mass of H2 remained in the reaction = 0.10 moles * 2 g/mole = 0.20 grams.

Organic substances that possess both amino and carboxylic acid functional groups are known as amino acids. Although hundreds of amino acids occur in nature, the alpha-amino acids that constitute proteins are by far the most significant. The genetic coding contains only 22 alpha amino acids. Amino acids are chemicals that make proteins when they combine. The building blocks of life are amino acids and proteins. Amino acids are left over after proteins are digested or broken down. To support the body, the human body utilizes amino acids to build proteins: Food should be broken down.

As the pH is given as 7.4 and pK of His is given as 6.00. There will occur a positive charge on His when it's pH < pK therefore, it is neutral at the given pH.

As the pK value of Lys is 10.53 that is greater than the pH of 7.40. Therefore, charge on Lys is positive.

As the pK value of Asp is 3.65 which is less than the pH value of 7.40. Hence, Asp has a negative charge.

1.50g of hydrofluoric acid is produced if 3.00 g of hydrogen reacts with excess fluorine with a 25 percent yield.

The balanced equation for the reaction of hydrogen (H2) and fluorine (F2) to form hydrofluoric acid (HF) is:

H2 + F2 -> 2HF

To calculate the amount of HF produced, we'll use the concept of theoretical yield and percent yield.

The theoretical yield is the maximum amount of product that can be formed based on the amount of reactants used.

Here, we're given that 3.00 g of hydrogen is used, so to find the theoretical yield of HF, we'll use the molar ratio of hydrogen to hydrofluoric acid in the balanced equation.

1 mol of H2 produces 2 mol of HF

So, 3.00 g of H2 produces 2*3.00g = 6.00g of HF

Percent yield is the ratio of the actual yield to the theoretical yield multiplied by 100%.

It's given that the yield is 25%.

So the actual yield of hydrofluoric acid will be:

Actual yield = (Theoretical yield) x (percent yield/100)

Actual yield = 6.00g x (25/100)

Actual yield = 1.50g

So, 1.50g of hydrofluoric acid is produced if 3.00 g of hydrogen reacts with excess fluorine with a 25 percent yield.

An Empirical formula is defined as the simplest whole number ratio of different atoms present in the molecule of a compound.

given,

mass of the unknown compound= 10.150 g

mass of phosphorus= 4.433 g

therefore, mass of oxygen

=mass of the unknown compound -  mass of phosphorus

=10.150-4.433 g

we know that

molar mass of oxygen = 16 g/mol

molar mass of phosphorus = 31 g/mol

number of moles of oxygen

=mass/molar mass

=5.717g/16gmol⁻¹

=0.357

number of moles of phosphorus

= mass/molar mass

Now, we will divide the moles by the smallest number of moles (0.143)

O= 0.357 / 0.143 =2.49≈ 2.5

P= 0.143 /0.143 = 1
