In which type of reaction do ions in two compounds switch places?
Reactions of the type AB + CD --> AD + BC are known as double displacement (sometimes double replacement) reactions.A and C are cations, B and D are anions, if these generic compounds are written in standard form.The cations and anions can be mono- or polyatomic.
What is the common name for potassium permanganate?
Yes. Sodium permanganate is an ionic compound comprising mono-atomic sodium cations and polyatomic permanganate anions.
Why are ionic solids brittle?
The reason why ionic compounds are brittle is because the ions in the compound are already held rigidly in place in a lattice due to the strong electrostatic forces of attraction in between the cations and the anions as well as the repulsion in the ions with like charges . However, if a large enough force is applied along a certain plane, this causes the ions to shift along that layer, displacing that layer with respect to the next, and there will hence be a repulsion between like charges within the ionic compound. This repulsion will shatter the crystal lattice of the ionic compound..
What is the structures of ionic crystal type AB?
since AB is an ionic crystel,it contaINS A+& B- IONS. Here B- ions are at the corners of a cube and at the edge centres. Each corner actually occupies 1\8 of B- ions &edge centre occupies 1\4 of B- ions. so the total no of B- ions in the crystal lattice is ( 1\8*8 + 1\4*12)=4 . While A+ ions are in the face centre & body centre of the crystal . so the total no of A+ ions in the crystal lattice =(1\2*6)+1=4.that is stoichiometrically ratio of A+ & B- ions is 4:4=1:1.Thus the stoichiometric formula of the compound is AB
The reason ionic compounds are brittle is because?
B) a strong repulsive force is created when cations suddenly align. I hate Plato >:o
Which of the following are always larger than the neutral atoms from which they are formed.. A. positive ions B. negative ions C. cations D. none of the above?
B. Negative ions. ( anions ) They have taken electron(s) into their valance shell and have increased their size this way.
Depolarization would occur.....a-sodium cations leave the cell b-potassium cations leave the cell c--chloride anions enter the cell d-calcium cations enter the cell?
In a polarized cell membrane there are an excess of sodium cations outside the cell and a relative abundance of potassium cations inside the cell. When a cell depolarizes, sodium ions rush into the cell causing the interior surface of the cell membrane to become slightly more positive, i.e. depolarized. When this happens it triggers potassium channels to open allowing potassium ions to flow out repolarizing the cell. While not completely correct, the best answer of your choices here would be b - potassium cations leave the cell.
In a solution a weak acid produces A a mixture of molecules and ions B all ions C all molecules D anions but no hydronium ions?
Answer A is correct: mixture of ions and moleculesH3O+ and B- and remaining part of UNdissociated HBIn which B- is symbolising any anion remaining from a protlysed part of an acid, e.g. HCl -> Cl-

What element forms cations?
The elements from group 1-13 or IA-IIIA (including all of the B groups) tend to form cations.Related Information:A cation is an element or molecule with a positive charge. This means that the element or molecule has lost one of its original electrons, making it less negative and therefore more positive.So elements that have an affinity to give away their electrons tend to form cations. In order for elements to want to give away their electrons the process must be favorable... The most favorable process is when an element ends up with a full valence octet. Elements with more than half their valence electrons end up with a full octet by gaining more electrons whereas elements with fewer than half their valence electrons end up with a full octet by losing their outermost valence electrons therefore becoming cations.
