Question

complete the table below.

some binary molecular compounds

name | chemical formula
sulfur tetroxide |
sulfur dioxide |
disulfur heptoxide |
disulfur trioxide |

Explanation:

To determine the chemical formulas of binary molecular compounds, we use prefixes to indicate the number of atoms of each element. The prefixes are: mono- (1), di- (2), tri- (3), tetra- (4), penta- (5), hexa- (6), hepta- (7), octa- (8), nona- (9), deca- (10). The first element is named first, followed by the second element with an -ide ending.

Step 1: Sulfur Tetroxide

The prefix "tetra-" means 4. So, sulfur (S) has 1 atom and oxygen (O) has 4 atoms.
Formula: $SO_4$

Step 2: Sulfur Dioxide

The prefix "di-" means 2. So, sulfur (S) has 1 atom and oxygen (O) has 2 atoms.
Formula: $SO_2$

Step 3: Disulfur Heptoxide

The prefix "di-" means 2 for sulfur, and "hepta-" means 7 for oxygen.
Formula: $S_2O_7$

Step 4: Disulfur Trioxide

The prefix "di-" means 2 for sulfur, and "tri-" means 3 for oxygen.
Formula: $S_2O_3$

Answer:

name	chemical formula
sulfur dioxide	$SO_2$
disulfur heptoxide	$S_2O_7$
disulfur trioxide	$S_2O_3$
