The answer choice which represents an aspect of the kinetic-molecular theory and can be used to explain compressibility of plasma is; Particles move independently of one another and are widely spaced.

<h3>What is the kinetic-molecular theory?</h3>

The kinetic-molecular theory in discuss postulates about the states of matter.

Also, it is built upon the idea that matter is composed of tiny particles that are constantly in motion.

Hence, the theory is explanatory of the observable properties and behaviours of solids, liquids and gases and hence, explains the compressibility of plasma.

Remarks;

  • Particles move independently of one another and are widely spaced.
  • Particle kinetic energy increases with increasing temperature.
  • Particles exert no attractive or repulsive force on one another.
  • Particles always move even when they have fixed positions.

Answer:

Explanation:

THE QUESTION SHOULD BE

Write the equilibrium constant expression, Kc, for the following reaction: If either the numerator or denominator is 1, please enter 1 CaCO3(s).

CaCO3(s) <=> Ca2+(aq) + CO32-(aq)

Write the mathematical form of the concentration of the products, then divide it by the concentration of the reactants as follows

Kc =[Ca2+]^1 . [CO32-]^1 / [CaCO3]^1

Answer: 1.  C. polar covalent: electrons shared between silicon and sulfur but attracted more to the sulfur

2. B)  NH_3

3. B) Fluorine

Explanation:

1. A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms.

Electronegativity difference = electronegativity of sulphur- electronegativity of silicon = 2.5 -1.8 = 0.7

Thus as electronegativity difference is less than 1.7 , the cond is polar covalent and as electronegativity of sulphur is more , the electrons will be more towards sulphur.

2. A molecular compound is usually composed of two or more nonmetal elements. Example: NH_3

Ionic compound is formed by the transfer of electrons from metals to non metals. Example: Mg_3N_2 , AlCl_3 and LiBr

3.  For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here K is having an oxidation state of +1 and as the compound formed is KZ, the oxidation state of non metallic element Z should be -1. Thus the element Z is flourine which exists as diatomic gas F_2

a block of iron has the dimensions of 3.00 cm x 3.00 cm x 3.00 cm. it has a mass of 213 g. what is its density? a. 638 g/cm3 b.
Juliette [100K]
Volume = 3 cm × 3cm × 3cm
             =  27 cm ³

Mass  =  213 g

Density  =  \frac{MASS}{VOLUME}
 
              = <span>\frac{213 g}{27 cm ^{3} }
</span> 
<span>              =  7.89 g / cm³

Thus answer is D.</span>
