To name the following ionic compounds, we need to determine the charges of the ions and use proper naming conventions. Here's how you can figure it out:

a. Li2O: To name this compound, identify the ions involved. Li is the symbol for lithium, and O is the symbol for oxygen. Since Li is a Group 1 element, it typically has a charge of +1. Oxygen, being in Group 16, typically has a charge of -2. To balance the charges and form a neutral compound, two Li ions are needed for every O ion. Therefore, the name of this compound is Lithium Oxide.

b. NaClO: In this compound, Na is the symbol for sodium, Cl is the symbol for chlorine, and O is the symbol for oxygen. Sodium, being in Group 1, typically has a charge of +1. Chlorine typically has a charge of -1. To balance the charges in the compound, one Na ion is needed for every ClO ion. The ClO ion is called hypochlorite, so the name of this compound is Sodium Hypochlorite.

c. Sr(CN)2: Here, Sr is the symbol for strontium, C is the symbol for carbon, and N is the symbol for nitrogen. Strontium, being in Group 2, typically has a charge of +2. Carbon and nitrogen form a polyatomic ion called cyanide (CN-), which has a charge of -1. To balance the charges, two CN ions are needed for every Sr ion. Therefore, the name of this compound is Strontium Cyanide.

d. Cr(OH)3: In this compound, Cr is the symbol for chromium, O is the symbol for oxygen, and H is the symbol for hydrogen. Chromium can have multiple charges, so we need to determine which one it has in this case. Oxygen typically has a charge of -2, and hydrogen typically has a charge of +1. To balance the charges, three OH ions (hydroxide) are needed for every Cr ion. Therefore, the name of this compound is Chromium Hydroxide.

e. Fe(CO3)3: Here, Fe is the symbol for iron, C is the symbol for carbon, and O is the symbol for oxygen. Iron can have multiple charges, so we need to determine which one it has in this case. Carbon and oxygen form a polyatomic ion called carbonate (CO3^2-), which has a charge of -2. To balance the charges, three CO3 ions are needed for every Fe ion. Therefore, the name of this compound is Iron (III) Carbonate.

f. Co(NO3)2: In this compound, Co is the symbol for cobalt, N is the symbol for nitrogen, and O is the symbol for oxygen. Cobalt can have multiple charges, so we need to determine which one it has in this case. Nitrogen and oxygen form a polyatomic ion called nitrate (NO3-), which has a charge of -1. To balance the charges, two NO3 ions are needed for every Co ion. Therefore, the name of this compound is Cobalt Nitrate.

g. (NH4)2SO3: Here, NH4 is the symbol for ammonium, and S is the symbol for sulfur. Ammonium is a polyatomic ion with a charge of +1. Sulfur can have multiple charges, so we need to determine which one it has in this case. Oxygen typically has a charge of -2. To balance the charges, two NH4 ions are needed for every SO3 ion. Therefore, the name of this compound is Ammonium Sulfite.

h. NaH2PO4: In this compound, Na is the symbol for sodium, H is the symbol for hydrogen, P is the symbol for phosphorus, and O is the symbol for oxygen. Sodium typically has a charge of +1. Hydrogen and phosphate (PO4^3-) form a polyatomic ion called dihydrogen phosphate (H2PO4-), which has a charge of -1. To balance the charges, one Na ion is needed for every H2PO4 ion. Therefore, the name of this compound is Sodium Dihydrogen Phosphate.

i. KMnO4: Here, K is the symbol for potassium, Mn is the symbol for manganese, and O is the symbol for oxygen. Potassium, being in Group 1, typically has a charge of +1. Manganese can have multiple charges, so we need to determine which one it has in this case. Oxygen typically has a charge of -2. To balance the charges, one Mn ion is needed for every four O ions. Therefore, the name of this compound is Potassium Permanganate.

j. Ag2Cr2O7: In this compound, Ag is the symbol for silver, Cr is the symbol for chromium, and O is the symbol for oxygen. Silver can have multiple charges, so we need to determine which one it has in this case. Chromium can have multiple charges as well. To balance the charges, two Ag ions are needed for every Cr2O7 ion. The Cr2O7 ion is called dichromate, so the name of this compound is Silver Dichromate.
