Answer #1

Salts with an alkali metal cation are soluble. --> true, alkali metals are pretty soluble

Salts with a nitrate anion are soluble. --> true, nitrate ions are very solubles

Most ionic compounds with chloride and bromide anions are soluble. --> False, depend son type of cation, specially transition metals will not do

Salts with the ammonium ion are soluble. --> True, ammonium ion is very soluble

The guidelines A–D all are valid. --> false, choose C

Net Ionic Equations In many chemical reactions of two or more compounds, ions are present in the solution that do not participate in the reaction. These ions, known as spectator ions, can be removed from the chemical equation describing the reaction. A chemical equation that has the spectator ions removed is known as a net ionic equation. Reactions between ionic compounds often result in the precipitation of an insoluble compound. Spectator ions and precipitation products of a chemical reaction can...

Which of th following are true regarding ions and ionic compounds? A) Ions form ionic bonds by sharing electrons. Metals tend to loose electrons and form positively charged ions (cations). B)Ionic compounds are formed from interactions between a atleast one metal ion (cation) and non-metal ion (anion). C)Negatively charged ions (anions) have a negative charge because they have lost one or more valence electron to become more stable. D) Positively charged ions (cations) have a positve charge because they have...
