Mariana [72]

Answer:

See explanation

Explanation:

An intrinsic property is a property that is internal, that is, it characterizes the substance under study. The possession of an intrinsic property depends on the nature of the substance. An intrinsic property does not depend on amount of substance but on the nature of the substance.

Examples of intrinsic properties include; Density. Solubility, Melting Point, Freezing Point, Boiling Point, Conductivity etc.

Intrinsic properties really represent the matter that is being studied. For instance, the boiling point of water will always be 100°c. No other liquid can boil exactly at that temperature. Hence, this intrinsic property can always be used to identify an unknown liquid as water.

The students were right, studying intrinsic properties accurately represent the matter that is being studied.

Which one of the following compounds is not covalent?
denpristay [2]
KCI is not a covalent compound, it is an ionic compound. 
A covalent compound is one in which each of the atoms involved contribute a specific number of electrons for sharing in order to from stable compound while an ionic compound is a compound formed when one atom donates electron to the other atom in the compound, in order to attain stability.  The compounds given in options A, B and D shared electrons while in KCl, potassium donates an electron to chlorine.

Bas_tet [7]

Answer:

2.2508\times 10^{19} m meter the mean free path of hydrogen atoms in interstellar space.Explanation:

The mean free path equation is given as:

\lambda =\frac{1}{\sqrt{2}\pi d^2 n}

Where"

d = diameter of hydrogen atom in meters

n =  number of molecules per unit volume

We are given: d = 100 pm = 100\times 10^{-12}= 10^{-10} m

n = 1 m^{-3}

\lambda =\frac{1}{\sqrt{2}\pi (10^{-10} m)^2\times 1 m^{-3}}

\lambda =2.2508\times 10^{19} m

2.2508\times 10^{19} m meter the mean free path of hydrogen atoms in interstellar space.
