To write the formula for the compound disulfur heptoxide, you first need to identify the prefixes: "di-" indicates two sulfur (S) atoms, and "hepta-" indicates seven oxygen (O) atoms. Therefore, the formula is written as ( \text{S}_2\text{O}_7 ). This reflects the composition of the compound, with two sulfur atoms and seven oxygen atoms.
The chemical formula of sulfuric acid is H2SO4.
To write the formula for the compound formed from beryllium (Be) and iodine (I), you first determine the charges of each element. Beryllium has a +2 charge as it is an alkaline earth metal, while iodine has a -1 charge as a halogen. To balance the charges, you need two iodine ions for each beryllium ion. Thus, the formula for the compound is BeI₂.
H2O A compound formed when hydrogen gas burns with oxygen.
The compound lithium oxide is written as Li2O. This indicates that it is composed of two lithium atoms and one oxygen atom.
To write the chemical formula of a compound using the Stock system, you need to indicate the charge of each element using Roman numerals in parentheses after the element symbol. For example, iron(III) chloride would be written as FeCl3, where Fe has a +3 charge and Cl has a -1 charge. Be sure to balance the charges to create a neutral compound.
The chemical formula of sulfuric acid is H2SO4.
The formula for the compound of barium and fluoride is BaF2.
To write a formula for an insoluble compound, you need to determine the charges of the ions involved and balance them to create a neutral compound. This involves using the crisscross method to determine the subscripts for each ion in the formula.
The formula for the binary compound of calcium and oxygen is CaO. This compound is known as calcium oxide.
It is written as Na2CO3. It is a base compound.
The chemical formula for the ionic compound containing calcium and fluorine is CaF2.
The formula for lithium oxide is Li2O.
The formula for boron chloride is BCl3. This compound consists of one boron atom bonded to three chlorine atoms.
To write the formula of a covalent compound, you need to determine the elements involved and their valencies. Use prefixes to indicate the number of atoms of each element in the compound. For example, in carbon tetrachloride (CCl4), the prefix "tetra-" indicates four chlorine atoms. The formula is then written as CCl4.
