Answer : The  question is to write the elements alphabetically and seperating them with commas.

So in this case for your question of Fireworks , KNO_{3},

The answer will be K, N, O.

You have to just differentiate the elements and write them according to the alphabetical order.

<u>Answer:</u> The elements present are potassium, nitrogen and oxygen.

<u>Explanation:</u>

Elements are defined as the substances in which same type of atoms are present. <u>For Example:</u> Sodium, Chlorine etc.

The chemical formula of the compound used in fireworks is KNO_3

The chemical name for the compound is potassium nitrate.

This compound is formed by the combination of three elements. In 1 mole of potassium nitrate, 1 mole of potassium atom, 1 mole of nitrogen atom and 3 moles of oxygen atoms are present.

Hence, the elements present are potassium, nitrogen and oxygen.

A mixture of He , Ar , and Xe has a total pressure of 3.00 atm . The partial pressure of He is 0.200 atm , and the partial press
yaroslaw [1]

The partial pressure of Xe is 2.60atm

The sum of the partial pressures is equal to the total pressure. Ptotal = P1 + P2 + P3... .To calculate the partial pressure of one of the components of a mixture, subtract the sum of known partial pressures of the other components from the total pressure.

Given the values of

PHe=0.20 atm

PAr=0.20 atm

Ptotal=3.00 atm

We need to find  PXe

Solution: Determine the sum of the partial pressures of helium and argon, then subtract the sum from the total pressure.

PHe+PAr =0.20 atm + 0.20=0.400 atm

PXe=3.00atm−0.400=2.60 atm

Each gas that makes up a mixture of gases has a partial pressure, which is the notional pressure of that gas as if it alone filled the original combination's complete volume at the same temperature.

According to Dalton's Law, a perfect gas mixture's total pressure equals the sum of its constituent gases' individual partial pressures.

The thermodynamic activity of a gas's molecules is gauged by its partial pressure.

Gases react, disperse, and dissolve based on their partial pressures rather than the concentrations they have in liquids or other gas combinations.

This general characteristic of gases holds true in biological chemical interactions involving gases.

Hence the partial pressure of Xe is 2.60atm

If you want to optimize environmental impact, the ores should be sifted at the site before transporting.

<h3>What is an ore?</h3>

An ore refers to the raw material from which a material is made. Usually, ores are obtained in the raw state from the earth. Metal ores are very important in the manufacturing industry.

In order to reduce the environmental impact of the manufacturing of ores in the metallurgical industry, the ores should be sifted at the site before transporting.
