Why are prefixes not used in naming ionic compounds?
two ions can combine in only one combination
What kinds of positive and negative ions always combine in one to one ratio?
Ions that have the same (for lack of a better word) absolute value of charge. Meaning 1+ and 1- ions will combine in a 1:1 ration (Na+ + Cl- --> NaCl), as will 2+ ions with 2- ions (Mg2+ + SO42- --> MgSO4) and 3+ ions with 3- ions (Al3+ + N3- --> AlN)
Lowest whole number ratio of ions in an ionic compound is a?
The lowest whole number ratio of ions in an ionic compound is determined by the ratio of positive to negative ions that combine to form a neutral compound. This ratio is typically expressed in the simplest whole number form, known as the empirical formula.
Which is formula for the compound made when magnesium ions and chloride ions are mixed?
When magnesium ions (Mg2+) and chloride ions (Cl-) are mixed, they combine in a 1:2 ratio to form magnesium chloride, which has the chemical formula MgCl2.
The ions Cr3 plus and O2- combine to form the ionic compound chromium oxide. In what proportions do these ions combine to produce a neutral compound?
The Cr3+ ion has a +3 charge, while the O2- ion has a -2 charge. To form a neutral compound, we need two O2- ions to balance the charge of one Cr3+ ion. Therefore, the ions combine in a 1:2 ratio to produce the ionic compound chromium oxide (Cr2O3).

In what ratio do calcium and hydroxide ions combine?
Calcium and hydroxide ions combine in a 1:2 ratio, where one calcium ion (Ca^2+) combines with two hydroxide ions (OH^-) to form calcium hydroxide (Ca(OH)2).
Why are prefixes not needed in naming iconic compound?
Ions combine in only one ratio. -APEX

How many moles of Cl- ions are needed to completely combine with 0.25 moles of Mg 2 ions?
Mg2+ + 2 Cl- are in 1 : 2 ratio (of ions) so also 0.25 : 0.50 mole ratio

What is the ratio of Femc003-1.jpg ions to Omc003-2.jpg ions in a neutral compound?
To determine the ratio of Femc003-1.jpg ions to Omc003-2.jpg ions in a neutral compound, you would need to consider the charges of the respective ions. Typically, ions in a neutral compound combine in ratios that balance their charges to achieve overall neutrality. If, for example, Femc003-1.jpg has a charge of +3 and Omc003-2.jpg has a charge of -2, the ratio would be 2:3 to balance the charges.
Do all ionic compounds have the same ratio of ions?
No. The ratio depends on the charges of the ions.
Substances that release ions that combine with hydrogen ions?
A base.
Will the hydrogen ion always combine with a water molecule?
No, hydrogen ions can combine with other molecules or ions besides water. For example, hydrogen ions can combine with hydroxide ions to form water, or they can bond with substances like ammonia or carbonates.
