What is the formula of the ionic compound expected to form between the elements Ba and O?

The ionic compound formed by reaction of the elements with atomic symbols K and O is named potassium oxide and has the formula unit K2O. (The lower case letters k and o are never proper atomic symbols!)


Suppose an element x is in group 2a and an element y is in group 7a the empirical formula for the compound between x and y?

The empirical formula for the compound between x and y would be xy. Since x is in group 2a and y is in group 7a, their charges would be 2+ and 7-, respectively. To balance the charges, one x would combine with three y to form the compound with the formula XY3.


If X is an element in Group 2A and Y is an element in Group 7A what would be correct about the compound that would form between X and Y?

They would form an ionic compound.


What is the compound that makes formula XY2?

The compound with the formula XY2 consists of one atom of element X and two atoms of element Y.


A compound has the formula X3YFor every 15 X atoms present in the compound how many Y atoms are there?

For every 15 X atoms in the compound X3Y, there would be 3 Y atoms. This is because the ratio of X to Y in the formula is 3:1, so for every 3 X atoms, there is 1 Y atom.


Is ca3p2 Ionic?

The solubility of calcium triphosphate in water is very low.


What is the empirical formula for the compound x3y12?

The empirical formula for the compound X3Y12 is X1Y4. This is determined by dividing the subscripts by the greatest common factor, which in this case is 3 for X and 12 for Y.


What is the formula for an ester?

X-OH + HOOC-Y = X-O-CO-Y + H2O alcohol + acid = ester + water so -O-CO- is an ester


The formula for a compound is represented x2y the oxidation number of y is 2 what is the oxidation number for x?

A molecule of a compound must be electrically neutral overall. There is only one y atom in the formula, so that the total contribution of charge from y is +2. There are two x atoms, and each of them must have an oxidation number of -1 for a total of -2 to neutralize the charge from y.


Compound X has the molecular formula C3H6 and Compound Y has the molecular formula C6H12. How are the two compounds related?

Compounds X (C3H6) and Y (C6H12) are related as structural isomers, specifically as a homologous series of alkenes. Compound Y can be seen as a dimer of Compound X, consisting of two units of C3H6. Both compounds share similar chemical properties due to their related structures, but they differ in molecular size and potential reactivity.
