(A) The balanced reaction equation shows that 1 mole of PbI 2 is produced from 2 moles of NaI. Therefore, only 1 mole of NaI w ...

(B) NaNO 3 is an ionic substance that dissociates into two ions, Na+ and NO 3 −. ...

(A) MgCl 2 is ionic because it is the product of an active metal (Mg) combining with a very active nonmetal (Cl). ...

(B) The electronegativity difference between H and Cl is between 0.5 and 1.7. This indicates an unequal sharing of electrons, w ...

(C) Ethane, CH 3 –CH 3 (g), has symmetrically arranged C–H polar bonds so that the ethane molecule is nonpolar covalent. ...

(E) Cu(s) is a metal. ...

(D) When hydrated copper sulfate is heated, the crystal crumples as the water is forced out of the structure, and a white powde ...

(A) When an ionic substance dissolves in water, the ionic substance breaks up into the ions that make it up. This process is ca ...

(C) Phenolphthalein is used as an acid–base indicator because it turns pink in the presence of a base. ...

(B) A substance that can act as both an acid and a base depending on what it is in the presence of is said to be amphoteric. ...

(E) Hygroscopic materials have the ability to absorb moisture from the air. Some hygroscopic materials have such an ability to ...

(T, F) The assertion is true that the most active metals are found in the upper left corner of the Periodic Table because of th ...

(T, T, CE) The assertion is explained by the reason. The graphic display of this is: ...

(T, F) The assertion is true but the reasoning is false. Transition elements have incomplete inner energy levels that are being ...

(F, T) The assertion is false and the reason is true. A supersaturated solution is holding more than its normal solubility, and ...

(F, T) Equilibrium is a dynamic condition because of the reason stated. The assertion is false; the reason, true. ...

(F, T) Covalent bonds are stronger than ionic bonds, generally. ...

(T, T, CE) An equilibrium system must have a gaseous reactant or product for pressure to affect the equilibrium. Then increased ...

(T, T, CE) The assertion is explained by the reason; both are true. ...

(T, T, CE) Both the assertion and the reason are true; they explain that the element’s orbital designation places it in the fir ...
