Write the formula for the following compounds: Example: potassium oxide + K1+ 02 31. magnesium sulfide 36. sulfur triiodide 32. cesium nitrate 37. hexene 33. lead (IV) oxide 38. sulfur hexafluoride 34. barium nitride 39. carbon tetrachloride 35. calcium bromide 40. propane

Answer 1

31. Magnesium sulfide: \(MgS\) 36. Sulfur triiodide: \(SI_3\) 32. Cesium nitrate: \(CsNO_3\) 37. Hexene: \(C_6H_{12}\) 33. Lead (IV) oxide: \(PbO_2\) 38. Sulfur hexafluoride: \(SF_6\) 34. Barium nitride: \(Ba_3N_2\) 39. Carbon tetrachloride: \(CCl_4\) 35. Calcium bromide: \(CaBr_2\) 40. Propane: \(C_3H_8\)

Answer 2

## Step 1 The first step in writing the formula for a compound is to identify the cation (positive ion) and the anion (negative ion). The cation is always written first in the formula. ## Step 2 Next, we need to balance the charges of the cation and anion to create a neutral compound. This is done by adjusting the subscripts of the cation and anion until the total positive charge equals the total negative charge. ## Step 3 Finally, we write the formula of the compound by combining the cation and anion with their respective subscripts.
