A compound has the formula X3YFor every 15 X atoms present in the compound how many Y atoms are there?
3
General formula of disaccharides?
Cx(H2 O)y
Is ca3p2 Ionic?
The solubility of calcium triphosphate in water is very low.
How do you calculate the mean ionic activity coefficient?
EAgCl,Ag = EoAgCl,Ag - 0.0257 In [y [HCl]] rearange the formula and put the y as ur subject which is basically the mean ionic activity coefficient u want
How do cations and anions form a compound that has no overall charge?
Cations have a negative charge and anions have a positive charge. Depending on their charges, x number of cations and y number of anions will join by force of attraction to form a balanced (chargewise) compound.An example:When an ionic compound is dissolved in water or is molten, the ions have the ability to move freely. When sodium chloride (NaCl) is dissolved in water, Na^+ and Cl^- can move around. When all the water evaporates, Na^+ and Cl^- ions will have been attracted to each other and will have formed a balanced ionic compound. If it's magnesium chloride (MgCl2), the Mg^2+ ion and two Cl^- ions will join by force of attraction and form a balanced ionic compound
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?
They would form an ionic compound.
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!)
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 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.
If a metal X with valency 3 combines with a non-metal Y with a valency 2, what will be the formula of the compound formed when X and Y combines?

What contains CHO in the ration of CH2O?
Carbohydrates such as GLUCOSE.The organic compound that contains C, H, and O in the ratio CH2O is the carbohydrate.glucose(C6H12O6)although this is not the general formula for sugarsthat would be: Cx(H2O)y
Which elements have compounds of the general formula XY?
Alkali metals (like Na and K) and halogens (like Cl and Br) have the general ionic formula format XY (X+ and Y- in solution)
