Because there is only one stable ionic compound made up of potassium and chlorine, and that is KCl. So calling is "mono chloride" or similar would be redundant assuming you understand basic chemistry (i.e. knowing oxidation numbers of K is +1 and Cl is -1). When compounds can exist in multiple forms in nature like CO and CO2 you will preferably indicate it through the nomenclature, calling one a monoxide and the other a dioxide.
The mass/volume percent of solution is 8.69% (m/v).
The change in pressure in a sealed 10.0L vessel is 5.28 atm
<u><em>calculation</em></u>
The pressure is calculated using the ideal gas equation
That is P=n RT
where;
P (pressure)= ?
v( volume) = 10.0 L
n( number of moles) which is calculated as below
<em>write the equation for decomposition of NH₄NO₂</em>
NH₄NO₂ → N₂ +2H₂O
<em>Find the moles of NH₄NO₂</em>
moles = molarity x volume in liters
= 2.40 l x 0.900 M =2.16 moles
<em>Use the mole ratio to determine the moles of N₂</em>
that is from equation above NH₄NO₂:N₂ is 1:1 therefore the moles of N₂ is also =2.16 moles
R(gas constant) =0.0821 l.atm/mol.K
T(temperature) = 25° c into kelvin = 25 +273 =298 K
make p the subject of the formula by diving both side by V
P = nRT/V
p ={ (2.16 moles x 0.0821 L.atm/mol.K x 298 K) /10.0 L} = 5.28 atm.

Explanation:
The kinetic molecular theory of gases depicts the characteristics and behavior of the gases in function of its particles (atoms or molecules).
As stated per the kinetic theory, a gas is consituted by a large amount of tiny particles in rapid random motion.
As result of this rapid continous motion, a huge number of particles are colliding at any moment against the walls of the vessel that contains the gas. The <em>gas pressure</em>, then, is the result of the force that the particles of gas exert over the walls of the container.
As per definition, the net force of may particles divided by the area gives the pressure: P = F / A.
So, the pressure is the force per unit area, which permits you to complete the sentence:
<em>Gas pressure results from the force exerted by a gas per </em><em><u>unit area.</u></em>

Answer in explanation below!
Explanation:
Box 1 : Eukarya - this is the domain of organisms that have cells enclosed within a nuclear envelope
Box 2: Protista - any eukaryotic organism that is not an animal, plant or fungus
Box 3: Fungi - they can be single celled ( unicellular ) or multicellular
Box 4: Eubacteria - they are prokaryotic microorganisms
I hope this helps, good luck!
