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 chemical formula of an ionic compound shows?
A. Co2 B. N2O C. NaCI D. C6H12O6
In which type of reaction do ions in two compounds switch places?
This type of reaction is called a double displacement reaction or a metathesis reaction. In these reactions, the positive and negative ions in two compounds exchange partners, resulting in the formation of two new compounds.
What is the common name for potassium permanganate?
Yes. Sodium permanganate is an ionic compound comprising mono-atomic sodium cations and polyatomic permanganate anions.
What is the structures of AB2 type ionic crystal?
AB2 type ionic crystal has a structure where cations of A occupy the corners of the unit cell and cations of B occupy the face-centered positions. An example of this structure is fluorite (CaF2) where calcium ions occupy the corners and fluorine ions occupy the face-centered positions.
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. Negative ions are formed when neutral atoms gain electrons, increasing their size due to the additional electron(s) while positive ions or cations are formed when neutral atoms lose electrons, reducing their size.
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.

What is the general format for a double-replacement reaction?
In a double-replacement reaction, the cations and anions of two ionic compounds switch places to form two new compounds. The general format is AB + CD -> AD + CB, where A and B are cations, and C and D are anions.
The chemical formula of an ionic compound shows?
A. Co2 B. N2O C. NaCI D. C6H12O6
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-

In ionic compounds what are the sum of the charges of all the cations and anions?
The positive and negative charges are equal in magnitude (absolute value).
MgO has the stacking sequence of .AcBaCb. n.What is the coordination geometry around O2- anions in the lattice A- Tetrahedral B- Square planar C- Octahedral D- Trigonal Prismatic E- Linear F- Trigona?
C- Octahedral. In the .AcBaCb. stacking sequence, the oxygen anions are surrounded by 6 magnesium cations in an octahedral coordination geometry.
IN which set do all elements tend to form anions in binary ionic compounds Question 3 options N S I Ca B K K Ga Pb Fe Hg Na?
In binary ionic compounds, elements that tend to form anions are typically nonmetals. From the given options, sulfur (S) and iodine (I) are nonmetals that commonly form anions (S²⁻ and I⁻, respectively) when they react with metals. Other elements listed, such as calcium (Ca), potassium (K), and iron (Fe), are metals that tend to form cations rather than anions.
What is the common name for potassium permanganate?
Yes. Sodium permanganate is an ionic compound comprising mono-atomic sodium cations and polyatomic permanganate anions.
A Base that completely ionizes in water is said to be A Strong B Weak C Neutral or D pH?
A. Strong. In a strong base, all of the molecules ionize in water to produce hydroxide ions (OH-) and cations. This results in a high concentration of hydroxide ions in the solution, leading to a high pH.
