How do you write the formula of ammonium carbonate by criss-cross method?
To write the formula of ammonium carbonate using the criss-cross method, you first write the symbols of the ions (NH4+) and (CO3^2-) side by side. Then, you criss-cross the numerical values from the charges of the ions to give you the formula NH42CO3.
What is the molecular formula of ammonium sulphate by crcriss cross method?
The molecular formula of ammonium sulfate is (NH4)2SO4. This is derived using the criss-cross method, which involves crossing the numerical charges of the ions to determine the subscript for each element in the compound.
What is the cris cross method of sodium chloride?
The criss-cross method is a technique used to determine the chemical formula of ionic compounds like sodium chloride. It involves swapping the numerical charges of the elements to create a balanced formula. For sodium chloride, the sodium ion (Na+) has a charge of +1, and the chloride ion (Cl-) has a charge of -1, so the formula becomes NaCl.
What is the chemical formula of potassium sulphate in criss-cross method?
The chemical formula of potassium sulfate using the criss-cross method is K2SO4. This method involves swapping the numerical values of the charges on the ions to determine the subscripts in the compound.
Molecular formula of water using criss cross method?
The molecular formula of water is H2O. This means that each water molecule contains two hydrogen atoms and one oxygen atom. The criss cross method is typically used for ionic compounds to determine the ratio of ions in the compound.

What is the answer for magnesium and carbonate using criss cross method?
The formula for magnesium carbonate using the criss-cross method is MgCO3. This is because the charge on magnesium is 2+ and the charge on carbonate is 2-, so when the charges are criss-crossed, the subscripts become 1 for Mg and 1 for CO3, resulting in MgCO3.

Why does this criss cross method give is a valid formula for an ionic compound?
The criss cross method helps determine the correct subscripts for ions in an ionic compound by ensuring that the charges balance out to zero. This method works because the total positive charge from the cation(s) must equal the total negative charge from the anion(s) to form a neutral compound. By swapping the numerical values of the charges on each ion to serve as subscripts in the compound formula, this balance is achieved.
What is the criss cross method of potasium?
The oxidation number of potassium is +1.
What is the formula for magnesium sulphite?
The chemical formula for magnesium sulfate is: MgSO4
How do you do the criss cross method?
The Criss Cross Method is used to find the general formula for ionic compounds. For monatomic ions, you simply take the absolute value of the ionic charge for the positively charge ion and make it the subscript for the negatively charged ion and vice versa. Example: Al +3 and Cl -1 The 3 becomes the subscript for the chloride ion and the 1 becomes understood for aluminum, to form aluminum chloride: AlCl3 Ionic compounds that form from polyatomic ions can also make use of the criss cross method. The only additional step is to include parenthesis around the polyatomic ion if it has a subscript other than one. Example: Mg+2 and OH-1 The 2 becomes the subscript for the hydroxide ion, but a set of parenthesis is needed to indicate 2 of each the O and the H. The 1 becomes the understood subscript for Mg. Magnesium Hydroxide: Mg(OH)2
