The best and most correct answer among the choices provided by your question is the second choice or letter B "<span>The K + ion and the negative end of the water molecule."

</span>First you may remember a tip: 

<span>Like dissolves like. This means </span>

<span>polar solvents will get polar and ionic substances dissolved and </span>

<span>non-polar solvents will dissolve non-polar substances. </span>

<span>In KI Potassium K is +vely charged and Iodie I is _negatively charged. </span>

<span>In water H-O-H, Hydrogen is +vely charged and Oxygen is -negatively charged. </span>

<span>Polar ends of water attract opposite ions of KI (or any other ionic or polar substance) thus the ionic compound will dissociate and will be dissolved.</span>


I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer is: D. The I⁻ ion and the positive end of a water molecule.

Dissociation of potassium iodide in water:

KI(aq) → K⁺(aq) + I⁻(aq).

Solvation is the interaction of solvent (water) with molecules or ions (in this example K⁺ and I⁻) in a solute.

Anion I⁻ has negative charge, so positive end (hydrogen atoms) of a water molecul attracts them.

Solvent (usually a liquid, but can also be a solid or a gas) is a substance that dissolves a solute.

Answer: 4KO_2+2CO_2\rightarrow 2K_2CO_3+3O_2

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical equation for reaction of potassium superoxide  with carbon dioxide to produce oxygen and potassium carbonate will be:

4KO_2+2CO_2\rightarrow 2K_2CO_3+3O_2

Nataly [62]

Explanation:

The force of gravity acting on an object is given by :

W = F = mg

Where W is the weight of an object

The force of gravity on house is 300,000 N. The force of gravity pulling down on your house would be exactly twice as much if your house has twice as much as mass because force of gravity is directly depends on mass.

80 POINTS!!! ALL PLATO USERS: asap!!!
Crank

This year course engages students in becoming skilled readers of prose written in a variety of periods, disciplines, and

rhetorical contexts and in becoming skilled writers who compose for a variety of purposes. More immediately, the course

prepares the students to perform satisfactorily on the A.P. Examination in Language and Composition given in the spring.

Both their writing and their reading should make students aware of the interactions among a writer’s purposes, audience

expectations, and subjects as well as the way generic conventions and the resources of language contribute to effectiveness

in writing. Students will learn and practice the expository, analytical, and argumentative writing that forms the basis of

academic and professional writing; they will learn to read complex texts with understanding and to write prose of

sufficient richness and complexity to communicate effectively with mature readers. Readings will be selected primarily,

but not exclusively, from American writers. Students who enroll in the class will take the AP examination.
