Why are polyatomic called radicals

Chemistry
1 answer:
Digiron [165]2 years ago
3 0
That’s because when a charged chemical species composes of two or more atoms (covalently bonded), they act as a single unit. the term radicals refers to free radicals that are with an unpaired electron and because not all of its electrons are found in pairs

A 1.78−L sample of hydrogen chloride (HCl) gas at 2.09 atm and 22°C is completely dissolved in 699 mL of water to form hydrochlo
patriot [66]

Answer:

M=0.960M

Explanation:

Hello,

In this case, it is firstly necessary to compute the dissolved moles of hydrogen chloride into the water as shown below:

n_{HCl}=\frac{PV}{RT}=\frac{2.09atm*1.78L}{0.082\frac{atm*L}{mol*K}*295.15K}=0.671molHCl

Thus, the molarity is computed as shown below:

M=\frac{0.671mol}{0.699L}=0.960M

Wherein no change in volume is considered, therefore the volume of the solution was the same volume of water.

Best regards.

Question 1:  Which of the following is true?

Answer:

            Figure II and Figure IV are both compounds.

Explanation:

                   Compound is a substance which is formed by chemical reaction of different elements.

Example:

              Water  =  H₂O  =  Which is made up of hydrogen and oxygen atoms.

              Carbon Dioxide  =  CO₂ =  Which is made up of carbon and oxygen                       atoms.

In given figures, Figure I and Figure III are not compounds because Figure I is containing a substance which is made up of same atoms like N₂, O₂, Cl₂ and Figure III is containing a substance which is made up of single monoatomic element like Ne, Kr, Xe gases.

Question 2:  Which of the following statement is true?

Answer:

            The Figure is the Molecule and a Compound

Explanation:

                    Molecules are formed when two or more, either same or different atoms join chemically. While, compound is any substance which formed when two different atoms join together chemically.

                    In given figure, it can be seen that the particles are made up of two atoms. Hence, it is said to be a molecule. Also, the atoms which are forming the molecule are different in color means, they are different atoms therefore, it is also called as compound.

Question 3:  Which of the following list includes only molecules?

Answer:

            Third List only include Molecules

Explanation:

                    Molecules are formed by the combination of two or more same or different atoms. In given options;

List 1 is containing a substance ( Mg ) which is existing in monoatomic form. It means we can exclude the first list.

List 2 is containing a substance ( Fe ) which is existing in monoatomic form. It means this list can also be excluded.

List 3 is containing all substances in molecular forms. Like NaCl made up of Na and Cl, N₂ made up of two nitrogen atoms and H₂O (water) made up of two hydrogen and one oxygen atoms.

List 4 is containing a substance ( He ) which is existing in monoatomic form. It means this list can also be excluded.

Iii. When the boat is fully loaded, it floats lower in the water than when it is empty. Explain
denis23 [38]

Answer:

The loaded ship will weigh more. Thus it will sink down farther in the water in order to displace that much more water so that it continues to float.
